What is the main idea of the Tiny Tutor? A comma represents a short pause, a period represents a longer one. Students' use of fragments is normally due to poor punctuation. Students usually know the difference between a complete and incomplete sentence.

all it means is function 3

y -5 = (-1/4)(x + 8)

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
