Haro has 17 model cars, 31 model trucks, and 9 model airplanes on the shelf in his room. his sister thought it would be funny to hide all the red models. now haro only has 39 models on his shelf. which number sentence could be used to find how many red models his sister hid?
a. (17 + 31 + 9) – r = 39
b. 17 + 31 + 9 + r = 39
c. (17 + 31 + 9) + r = 39
d. 39 + 17 + 31 + 9 = r

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option

step-by-step explanation: w

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
