Answer:
40
Step-by-step explanation:
36 = 90% × (number of questions)
36/0.90 = (number of questions) = 40 . . . . . divide by the coefficient of the variable
There were 40 questions on the test.

-6 < x ≤ 6
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
To find the slope m use any 2 ordered pairs from the table.
Calculate m using the slope formula
m = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
with (x₁, y₁ ) = (- 4, 11) and (x₂, y₂ ) = (2, - 1)
m =
=
= - 2 → B
It would be e, because it went down 10 instead of 5
Answer:
200
Step-by-step explanation:
If there are 2 squares next to eachother with the same area, then their perimeter is 6*sidelength.
60 = 6*sidelength
10 = sidelength
Square the sidelength to find the area of the square. 10^2 = 100
Multiply that by 2 to find the area of the rectangle. 100*2 =
200
