The sum of a number and two is equal to the quotient of six and negative four

Equation is x+2 = -6/4

         Solving the value of x is -3.5

Step-by-step explanation:

Let number be x  

sum of x and 2 = x+2

Quotient of 6 and -4 is  6/-4.

So equation is

x+2 = -6/4

x+2 = -1.5

x = -1.5-2

x= -3.5

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

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
