Can someone please help me solve this question? 7-3r=r-4(2+r)
Answer:
There is no solution
Step-by-step explanation:
7−3r=r−4(2+r)
Step 1: Simplify both sides of the equation.
7−3r=r−4(2+r)
7+−3r=r+(−4)(2)+(−4)(r)(Distribute)
7+−3r=r+−8+−4r
−3r+7=(r+−4r)+(−8)(Combine Like Terms)
−3r+7=−3r+−8
−3r+7=−3r−8
Step 2: Add 3r to both sides.
−3r+7+3r=−3r−8+3r
7=−8
Step 3: Subtract 7 from both sides.
7−7=−8−7
0=−15

There are no solutions.
A line passes through the point (-5,-2) and (0,2) write the equation in point-slope form
Answer:
y=4/5x+2
Step-by-step explanation:
Answer:
y=0.8x+2
Step-by-step explanation:
First, you would figure out the slope using the following equation: (y2-y1)/(x2-x1)=slope.
So, (2--2)/(0--5)= 4/5, or 0.8. This would be the slope.
Then, you would figure out b by putting a data point from the given ones. I chose (0, 2).
2=0.8(0) + b --> 2=0 + b --> 2=b
So, the final equation is y=0.8x+2

Given the figure below find the values of x and z.
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
So first I would do...[tex]9x+39+12x-48=180[/tex] first because it'll give me the x value, so....
[tex]9x+39+12x-48=180\\21x-9=180\\21x=189\\x=9[/tex]
So now we know that the x equals 9 so we plug it in for (9x+39) because it's vertical to the other angle across from it and vertical angles are always congruent, so...
[tex]z=9(9)+39\\z=81+39\\z=120[/tex]
so now we know that x=9 and z=120.

Find the Highest Common Factor of 120 and 150.
Answer:
30
Step-by-step explanation:
120 divided by 30 is 4, and 150 divided by 30 is 5.
Answer: What is the greatest common factor of 120 and 150? The greatest common factor of 120 and 150 is 30, because 30 is the highest number that is divisible by both numbers.
Determine whether the given lines are parallel, perpendicular or neither.
2x + 3y = 1
3x – 2y = 1
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
These two equations are perpendicular it's pretty tough to figure it out with the only the equations like last time but if you graph it's more easier because it's visual.
So the equations solved for y is...
[tex]y=-\frac{2}{3} x+\frac{1}{3}[/tex]
[tex]y=\frac{3}{2}x-\frac{1}{2}[/tex]
Refer to the figure at the right. If
m22 = (a + 15)° and m23 = (a + 35)°, find the
value of a such that HĽ I HJ.
Answer:m∠1 = 145°
m∠2 = 35°
m∠3 = 35°
m∠4 = 145°
m∠5 = 145°
m∠6 = 35°
m∠7 = 35°
m∠8 = 145°
Step-by-step explanation:
The required value of a is 20°.
What are complementary angles?In geometry, complementary angles are defined as two angles whose sum is 90 degrees. In other words, two angles that add up to 90 degrees are known as complementary angles.
Now it is given that,
m22 = (a + 15)° and m23 = (a + 35)°
Let m22 and m33 be the angle between HL and HJ.
And since HL is perpendicular to HJ therefore they are complement ot each other.
Thus,
m22 + m23 = 90°
⇒ (a + 15)° + (a + 35)° = 90°
⇒ a° + 15° + a° + 35° = 90°
⇒ 2a° +50° = 90°
⇒ 2a° = 90° - 50°
⇒ 2a° = 40°
⇒ a° = 40°/2
⇒ a° = 20°
Thus, the required value of a is 20°.

the function f(x)=5(2)x represents number of bacteria, f(x), growing in a culture after x hours. How many bacteria are in the culture after 3 hours?
=============================================
Explanation:
Assuming the function is f(x) = 5(2)^x, then we replace every x with 3. Then we use the order of operations PEMDAS to simplify. Or we can use a calculator to simplify in one step.
f(x) = 5(2)^x
f(3) = 5(2)^3
f(3) = 5(8)
f(3) = 40

On Monday, Jayla raised $ 30 and Carlos raised $ 50. After that, Jayla raised $ 12 per day and Carlos raised $ 7 per day. After how many days will they have raised the same amount? They will raise the same amount after days. (Only type in the number for your final answer)
Answer:
4 days
Step-by-step explanation:
For Jayla:
[tex]Base\ Amount = \$30[/tex]
[tex]Additional = \$12[/tex] daily
For Carlos:
[tex]Base\ Amount = \$50[/tex]
[tex]Additional = \$7[/tex] daily
Represent the number of days with d
Jayla's expression can be represented using:
[tex]30 + 12*d[/tex]
Carlos' can be represented as:
[tex]50 + 7 * d[/tex]
Equate both expressions:
[tex]50 + 7 * d = 30 + 12 * d[/tex]
[tex]50 + 7d = 30 + 12d[/tex]
Collect Like Terms
[tex]12d - 7d = 50 - 30[/tex]
[tex]5d = 20[/tex]
Solve for d
[tex]d = 20/5[/tex]
[tex]d = 4[/tex]

The amount of available disk space on a digital video recorder changed from 81% to 9% after recording 12 episodes of a show. Each episode requires the same amount of disk space. Which statement is true? The change in available disk space is 6% per episode. The change in available disk space is −6% per episode. The change in available disk space is 7.5% per episode. The change in available disk space is −7.5% per episode.
Answer:
The change in available disk space is −6% per episode
Step-by-step explanation:
Given that :
Available disk space changed from 81% to 9% after recording 12 episodes of a show
Each episode requires the same amount of disk space
Change in disk space =
Final % = 9%
Initial percentage = 81%
Change = final value - initial value :
(9 - 81)% = -72%
72% reduction in disk space
Space taken up per episode :
Reduction in space / number of episodes
= -72% / 12
=- 6%
Help! marking branliest answer if gotten right!
Answer: x= 65
Step-by-step explanation:
Vertical angles are equal to each other. So, to solve, write the equation:
2x - 10 = 120
Add 10 to both sides
2x = 130
Divide both sides by 2
x = 65
A=pir^2 solve for pi
Given problem;
A = [tex]\pi[/tex] r²
Solve for π;
To solve for π implies that we make it the subject of the expression.
So;
A = π r²
Now multiply both sides by [tex]\frac{1}{r^{2} }[/tex]
So;
A x [tex]\frac{1}{r^{2} }[/tex] = [tex]\pi[/tex] x r² x [tex]\frac{1}{r^{2} }[/tex]
r² cancels out from the right side and leaves only π;
π = [tex]\frac{A}{r^{2} }[/tex]
So [tex]\pi = \frac{A}{r^{2} }[/tex]
What is the length of 15,409,000 cubic yard in miles? (to
the nearest hundred)
Answer:
Step-by-step explanation:
The cube root of 15,409,000 = 248.84 yards.
There are 1760 yards in a mile
One edge of a cube = 248.84 / 1760 = .141386 miles.
So a cube would be .00283cubic miles. Your answer does not reach a hundredth place, I don't think.

Find the value of b for the triangle using the Pythagorean Theorem.
Step-by-step explanation:
Hey there!
Given;
The given figure is a Right angled triangle, taking reference angle as angle B.
Hypotenuse= AB=5
Base= CB= 4
Perpendicular= AC=b
Using Pythagorean theorem.
[tex] {h}^{2} = {p}^{2} + {b}^{2} [/tex]
[tex]p = \sqrt{ {h}^{2} - {b}^{2} } [/tex]
Put all values.
[tex]b = \sqrt{ {5}^{2} - {4}^{2} } [/tex]
[tex]b = \sqrt{25 - 16} [/tex]
[tex]b = \sqrt{9} [/tex]
Therefore, the value of b is 3.
Hope it helps...
