how to find x of the (x+95) and (4x-10)
Answer:
x=35
Step-by-step explanation:
x+95=4x-10
Subtract x on both sides
95=3x-10
Add x on both sides
105 = 3x
x=35
Hope this helps plz hit the crown :D
Answer:
x = 35
Step-by-step explanation:
(x + 95) = (4x - 10) get rid of the parentheses
x + 95 = 4x - 10 put the x's together and put your constants together
105 = 3x divide 3 from both sides
35 = x

Aleena expands 2xx+3-5(x-2) as 2x2+3-5x-10. Has she expanded it correctly? Please identify the mistakes and write the correct way in which 2xx+3-5(x-2) should be expanded.
The given expression is :
2xx+3-5(x-2)
We know that, [tex]x{\cdot}x=x^2[/tex]
[tex]=2x^2+3-5(x-2)\\\\=2x^2+3+(-5)(x)+(-5)(-2)\\\\=2x^2+3-5x+10[/tex]
Aleena expands 2xx+3-5(x-2) as 2x²+3-5x-10. She is mistaken because the sign before 10 should be +10 instead of -10. Hence, the correct expanded form is 2x²+3-5x+10. Hence, this is the required solution.

Answer:
Statement F is true
Step-by-step explanation:
Let x represent number of yoga classes
Let y represent total cost
Let m represent the additional fee per yoga class
Let b represent the membership fee
y=mx+b
Notice that after every 2 classes, the price goes up by 7.5 so m=7.5/2
m=3.75
Thus the first statement is true
Note you can also find the membership fee if you plug this in with some points
y=mx+b
67.5=3.75(6)+b
b=45 so membership fee is $45
Solve for x and y. (5x+2) y 6x
Answer:
x=8
y=138
Step-by-step explanation:
5x+2+6x=90
11x+2=90
11x=88
x=8
y+5x+2=180
y+40+2=180
y+42=180
y= 138
I need help with this question can anyone help ?
Answer:
m < 1 = 72
Step-by-step explanation:
Since we know that line l and line m are parallel and that p is one of their transversals, it sets up a situation where we can identify which angles are congruent (equal) to one another according to their positions.
In this case, we can see that < 3 and < 1 are in the same matching corners created by the transversal. When angles are in the same matching corners they are called corresponding angles - and according to the Corresponding Angles Postulate, corresponding angles are congruent.
Therefore, m < 3 = m < 1, and since it's given that m < 3 = 72, we know that m < 1 = 72 too.
The width of a box is two-third of it's length and height is one-third of it's length.If the volume of the box is 384 cubic meter,find the dimensions of the box.
Answer:
Length = 12
Width = 8
Height = 4
Step-by-step explanation:
Let length of box = l
Width = 2/3 * l
Height = 1/3 * l
Volume of the box = 384 ft³
Volume = Length * width * height
Volume of box = l * 2/3 l * 1/3 l
384 = 2l³ / 9
384 * 9 = 2l³
3456 = 2l³
l³ = 3456 / 2
l³ = 1728
Take the Cube root of 1728
l = 12
Length = 12
Width = 2/3 * 12 = 8
Height = 1/3 * 12 = 4

find the inverse with respect to addition of -6
Given:
The number is -6.
To find:
The inverse with respect to addition of the given number.
Solution:
We need to find the additive inverse of -6, to get the inverse with respect to addition of -6.
We know that, the sum of a number and its additive inverse is 0.
Let the additive inverse of -6 be x. Then,
[tex]-6+x=0[/tex]
Adding 6 on both sides, we get
[tex]-6+x+6=0+6[/tex]
[tex]x=6[/tex]
Therefore, the inverse with respect to addition of -6 is 6.

A scientist add drops of liquid to a test tube. Each drop contains o.14mL. After 6 drops how much liquid has the scientist added?
Answer:
We conclude that after 6 drops how much liquid the scientist has added 0.84 mL.
Step-by-step explanation:
Given that the scientist adds drops of liquid to a test tube.
The amount of liquid in 1 drop = 0.14 mLIn order to determine the amount of liquid after 6 drops, all we need is to multiply 0.14 mL by 6.
i.e.
The amount of liquid in 6 drops = 0.14 × 6
= 0.84 mL
Therefore, we conclude that after 6 drops how much liquid the scientist has added 0.84 mL.

A June 2009 Harris Interactive poll asked people their opinions about the influence of advertising on the products they buy. Among the people aged 18 to 34 years, 45% view advertisements as being influential, whereas among the people aged 35 to 44 years, 37% view advertisements as being influential. Suppose that this survey included 655 people in the 18- to 34-year age group and 420 in the 35- to 44- year age group. At the 1% significance level, can you conclude that the proportion of all people aged 18 to 34 years who view advertisements as being influential in their purchases is greater than the proportion of all people aged 35 to 44 years who hold the same opinion
Answer:
We accept with 99 % of confidence that p₁ ( the proportion in the group aged 18 - 34 ) is bigger than p₂ (the proportion in the group aged 35-44)
Step-by-step explanation:
Group aged 18 - 34
Sample size n₁ = 655 sample size enough to apply a normal distribution aproximation for the test
p₁ = 0,45 and q₁ = 1 - p₁ q₁ = 0,55
p₁*n₁ = 0,45*655 = 294 q₁*n₁ = 0,55*655 = 360
both bigger than 5
p₁ = 45 % or p₁ = 0,45 then q₁ = 1 - 0,45 q₁ = 0,55
Group aged 35 - 44
Sample size n₂ = 420 sample size enough to apply a normal distribution aproximation for the test
p₂ = 37% p₂ = 0,37 and q₂ = 0,63
p₂*n₂ = 0, 37*420 = 155 q₁*n₁ = 0,63*420 = 264
Test Hypothesis
Null Hypothesis H₀ p₁ = p₂
Alternative Hypothesis Hₐ p₁ > p₂
Significance level α = 1% α = 0,01
Confidence Interval CI = 99 %
Then from z table we find critical z z (c ) = 3,1
Calculating z(s)
z(s) = ( p₁ - p₂ )/ √[ ( p₁*q₁)/n₁ ] + [ (p₂*q₂)/n₂ ]
z(s ) = (0,45 - 0,37 ) / √ 0,45*0,55)/655 + 0,37*0,63 /420
z(s) = 0,08 /0,03
z(s) = 2,66
Comparing z(s) and z(c)
z(s) < z(c)
Then z (s) is inside the acceptance region for H₀

Answer:
9 cm.
Step-by-step explanation:
First, let's form an equation. We'll represent the final depth of snow on Cherry Street with the variable d. We'll represent the hours with the variable h.
10 - 1/3h = d
Now, you already know what h equals so you can replace h with 3 for 3 hours.
10 - 1/3(3) = d
1/3 * 3 = 1.
10 - 1 = d
10 - 1 = 9
Now, we know what d equals.
10 - 1/3(3) = 9.
Do NOT forget the unit of measurement in your final answer, cm. In the photo, it looks as though it has already been provided.
The final answer is 9 cm.
Can some on check over my work pls
Not exactly correct.
y=mx+b Slope is m and y intercept is b.
So, here count the units for the slope. it goes barley to the 7th box. Now, count the units for the y intercept. It goes to the fourth box.
Thus, your equation is y=7x+4

Blake drives 448 miles on 16 gallons. How many miles does Blake drive on one gallon?
Answer:
28
Step-by-step explanation:
i just divided 448 and 16 and got that, om on that same question
here is how to divide that so you know on your own
Step 1:
Start by setting it up with the divisor 16 on the left side and the dividend 448 on the right side like this:
1 6 ⟌ 4 4 8
Step 2:
The divisor (16) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:
0
1 6 ⟌ 4 4 8
Step 3:
Multiply the divisor by the result in the previous step (16 x 0 = 0) and write that answer below the dividend.
0
1 6 ⟌ 4 4 8
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.
0
1 6 ⟌ 4 4 8
- 0
4
Step 5:
Move down the 2nd digit of the dividend (4) like this:
0
1 6 ⟌ 4 4 8
- 0
4 4
Step 6:
The divisor (16) goes into the bottom number (44), 2 time(s). Therefore, put 2 on top:
0 2
1 6 ⟌ 4 4 8
- 0
4 4
Step 7:
Multiply the divisor by the result in the previous step (16 x 2 = 32) and write that answer at the bottom:
0 2
1 6 ⟌ 4 4 8
- 0
4 4
3 2
Step 8:
Subtract the result in the previous step from the number written above it. (44 - 32 = 12) and write the answer at the bottom.
0 2
1 6 ⟌ 4 4 8
- 0
4 4
- 3 2
1 2
Step 9:
Move down the last digit of the dividend (8) like this:
0 2
1 6 ⟌ 4 4 8
- 0
4 4
- 3 2
1 2 8
Step 10:
The divisor (16) goes into the bottom number (128), 8 time(s). Therefore put 8 on top:
0 2 8
1 6 ⟌ 4 4 8
- 0
4 4
- 3 2
1 2 8
Step 11:
Multiply the divisor by the result in the previous step (16 x 8 = 128) and write the answer at the bottom:
0 2 8
1 6 ⟌ 4 4 8
- 0
4 4
- 3 2
1 2 8
1 2 8
Step 12:
Subtract the result in the previous step from the number written above it. (128 - 128 = 0) and write the answer at the bottom.
0 2 8
1 6 ⟌ 4 4 8
- 0
4 4
- 3 2
1 2 8
- 1 2 8
0
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 448 divided by 16 calculated using Long Division is:
28
0 Remaind
