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

C, D, F
Step-by-step explanation:
She walked 12 miles. Then she walked 1/4 that distance. "That distance" is 12 miles.
That means she walked 12 miles plus 1/4 of 12 miles.
She walked
12 + 1/4 * 12
You can factor out 12 from the expression above, and write it as
12(1 + 1/4)
Now you can do the addition in parentheses.
12(1 + 1/4) = 12(4/4 + 1/4) = 12(5/4)
Answer:
C, D, F
