Answer:
3) 8
4) 5.25 cups
Step-by-step explanation:
3) cross multiply:
36 × 10 = 360
45 × x = 45x
equate them both:
360 = 45x
divide both sides by 45
360 ÷ 45 = 8
x = 8
4) 8 people : 3 cups of flour
14 people : how many cups?
14 ÷ 8 = 1.75
to get from 8 people to 14 people we multiply by 1.75, so do the same thing to the 3 cups:
3 × 1.75 = 5.25 cups
Answer:
rectangle, quadrilateral, and square are all right. maybe kite too but I dont think so-
B is correct.
A. 5(x-2)= 5x-10
B. 4(x+3)= 4x + 12
C. 3(x+1)= 3x+3
D. 2(x+7) = 2x + 14
Basically put it in a calculator
That would be the SSS postulate.
