Answer:
x = 4
Step-by-step explanation:
3x - 10 = 2 | Given
3x = 12 | Add 10 to both sides to isolate 3x
x = 4 | Divide both sides by 3 to get the value of x
Answer:
4
Step-by-step explanation:
3x - 10 = 2
add
3x = 12
divide
x = 4
Ravi has to take a walk around a field once. If the field is 15 m long and 20 m wide, then how many metres does he have to walk?
Answer: 70 m
Step-by-step explanation:
The field described has the shape of a rectangle because one side is longer than the other.
The length that Ravi would have to walk therefore is the perimeter of this rectangle.
Perimeter = 2 × ( Length + Width)
= 2 × ( 15 + 20)
= 2 × 35
= 70 m

Answer:
90 I think bc I saw the right angle
find the are of the ABC triangle
Answer:
The area of the triangle is 48 square centimeters.
Step-by-step explanation:
The area of a triangle is base times height times a half. So the area of the triangle is 12 * 8 / 2 = 6 * 8 = 48 square centimeters.
plz help me and show your work
This is simple:
First of all, let us take the first equation:= 4x - 2y = 8
Put x = 0
= 4 ( 0) - 2 y = 8
= 0 - 2y = 8
= -2y = 8
= y = 8/-2
= y = - 4
So, the solution will be ( 0, -4)
For second equation,= y = ½ x + 2
Put x = 0
= y = ½ × 0 + 2
= y = 0 + 2
= y = 2
So, the solution will be ( 0, 2 ).
Now plot these points on the graph.Note*- I have taken x = 0 for easy calculation, you can take any number of your choice._________________________Paul’s dad drives on the highway at an average rate of 70 miles per hour. If the entire trip is driven on a highway, how many driving hours will be required for the trip
Answer:
The answer would be based off of how many miles the dad went so if he went to say 140 miles then it would be 2 hours.
Step-by-step explanation:
Just go to your calculator and divide how many miles he went by 70 then it will give you the amout of hours he went.

Suppose that 8% of all cars produced at Plant A have a certain defect, and 5% of all cars produced at Plant B have this defect. A quality control manager takes separate random samples of 150 cars from each plant. The manager will then look at the difference (A-B) between the proportions of cars with the defect in each sample.
What will be the shape of the sampling distribution of the difference in sample proportions, and why?
Choose 1 answer:
A. Approximately normal, because we expect 12 defective and 138 defect-free cars from Plant A, and 15 and 135 from Plant B, and all of these counts are at least 10.
B. Approximately normal, because we expect 16 defective and 134 defect-free cars from Plant A, and 10 and 140 from Plant B, and all of these counts are at least 10.
C. Not normal, because we expect fewer than 10 defective cars in Plant A.
D. Not normal, because we expect fewer than 10 defective cars in Plant B.
Answer:
Not normal, because we expect fewer than 10 defective cars in plant B
Step-by-step explanation:
Answer: D
Not normal, because we expect fewer than 10 defective cars in Plant B. [tex].05*150=7.5[/tex]

A student has 6 nickel 14 dimes and 8 quarter.what is the ratios of the total number of coins to the number of nickels ? In simplest form
Given:
A student has 6 nickel 14 dimes and 8 quarter.
To find:
The ratio of the total number of coins to the number of nickels.
Solution:
We have,
Number of nickels = 6
Number of dimes = 14
Number of quarter = 8
Total number of coins = 6+14+8
= 28
Now, the ratio of the total number of coins to the number of nickels is
[tex]Ratio=\dfrac{\text{Total number of coins}}{\text{Number of nickels}}[/tex]
[tex]Ratio=\dfrac{28}{6}[/tex]
[tex]Ratio=\dfrac{14}{3}[/tex]
[tex]Ratio=14:3[/tex]
Therefore, the ratio of the total number of coins to the number of nickels is 14:3.

write down three integers, all less than 25 whose range is 10 and mean is 13
Answer:
Step-by-step explanation:
we have the mean=13
(x+y+z)/3=13
x+y+z=39
range=highest value-lowest value=10
lets say x= highest value
y=lowest value
x-y=10
x=10+y
the numbers are 9,11,19
19-9=10 range
sum is 39
i need help with number 1
Answer:
Step-by-step explanation:
Given
Points: (0,3) and (-4,-1)
Formula
x = 0 to find the y intercept
m = (y2 - y1)/(x2 - x1)
Solution
y2 = 3
y1 = - 1
x2 = 0
x1 = - 4
m = (3 - -1)/(0 - - 4)
m = 4/4
m = 1
You have y = mx + b so m = 1
the general equation becomes y = x + b
Use point (0,-4)
y = x + b
- 4 = 0 + b
b = - 4
y = x - 4

A pentagon is transformed according to the R 180 degrees. Which is another way to state the transformation?
Answer:
(x, y) → (–x, –y)
Step-by-step explanation:
Given
[tex]R_0, 180^{\circ}[/tex]
Required
Another way to write the above transformation
The above transformation means 180 degrees clockwise rotation.
When a coordinate point (x,y) undergoes this type of transformation, the new coordinate point becomes (-x,-y).
Hence, another way to write [tex]R_0, 180^{\circ}[/tex] is (x, y) → (–x, –y)

1. Gloria says the two expressions - (12x + 24) - 9x and -6(x + 1) are equivalent. Is she correc Explain how you know.
Answer:
No they aren't equivalent
Step-by-step explanation:
Let's take each expression
the first one is
- (12x+24) - 9x = -12x -24 -9x = -21x -24 = -3 (7x +8)
the second expression
-6 (x+1) = -6x-6
So they aren't equivalent

3² • 9³ = [ ]
solve
Answer:
3⁸ or 6561
Step-by-step explanation:
First, let's look at PEMDAS - Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.
There are no parentheses, so let's solve the exponents.
3² • 9³
3² = 9
9³ = 729
Your expression is:
9 • 729
Now let's multiply.
= 6561
This number can also be expressed with exponents.
Since 9 = 3², 9³ = 3²⁽³⁾
Now your expression is:
3² • 3²⁽³⁾
First, solve the exponents by multiplying.
3² • 3⁶
When you multiply two expressions with exponents that have the same base (3), you add the exponents.
3² • 3⁶ = 3⁽²⁺⁶⁾ = 3⁸
3⁸ also equals 6561.
Your answer is 3⁸ or 6561.
Hope this helps!

Which proportion can be used to find n?
Answer:
n = 2
Step-by-step explanation:
If two triangles are similar, their corresponding sides will be proportional.
Both the triangles in the given picture similar.
Therefore, by the property of similar triangles,
Corresponding sides of the given triangles will be proportional.
[tex]\frac{1}{2}=\frac{n}{4}[/tex]
n = [tex]\frac{4}{2}[/tex]
