The integers from -3 to +3 can be used in the blanks below. which of these integers produces a positive, even integer for the expression? -8/2+4 () -2 =

My daughter filled the paren with a 3, but I though the question asks for a positive, even integer.

Plugging in 3 does in fact produce a positive, even integer.

Step-by-step explanation:

-8/2 + 4(3) - 2 = ?

-4 + 12 - 2 = ?

? = 6

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
