HELP ME PLS I NEED THIS TODAY Explain how you would simplify the expression 3x + 7y - 2x + 3y + 7? What are the "like terms"? What is your answer?

3x-2 equals 1x

7y+3y= 10y

1x+10y+7

Step-by-step explanation:

to simplify the expression you combine like terms. The like terms are ay 2 terms with the same letter so the x's together and y's together.

the ratio of grapes to blueberries she should use is 12: 3

step-by-step explanation:

if mandie is making 15 cups of fruit salad, the ratio of grapes to blueberries she should use is 12: 3.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
