Which is an example of an expression?
O 3x – 4
O 3/4x = 14y
0 10 = 2・5
O 2 < 5x

Your answer would most likely be A.

Step-by-step explanation:

A is an expression, it does not include an equal sign in the problem.

B includes a equal sign, it is not an expression it is an equation.

C also includes a equal sign, therefore not an expression.

B is not and expression, even though it does not have a equal sign, it is not a expression. When using "<" its just saying that 5 times a number is more then 2.

I hope this is correct! Im only in 8th grade, don't come at me if this is incorrect! That would be my guess.

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
