Answer:

They need to sell 30 cups of lemonade for them to earn the same amount of money.

Step-by-step explanation:

1. Write out the equation:

- 1.5x - 35= x - 20

2. Subtract x on both sides to isolate the variable on one side of the equation:

1.5x - x - 35 = x - x - 20

3. Solve for x:

0.5x - 35 =  -20

0.5x - 35 + 35 = -20 + 35

0.5x = 15

0.5x/0.5 = 15/0.5

x =30

Answer:

Step-by-step explanation:

1.5x - 15 dollars = x - 20    Add 15 to both sides.

1.5x - 15 + 15 = x - 20 + 15

1.5x = x - 5                          They will never coincide.

1.5x-x = - 5

0.5x = - 5                            Multiply by 2

x = - 10

I would check your question.

Solve and graph the following inequality: 3(7x+17) > -19 + 14x
love history [14]

Answer:

Solving the inequality we get: \mathbf{x>-7}

Step-by-step explanation:

We need to solve and graph the inequality 3(7x+17) > -19 + 14x

Solving:

3(7x+17) > -19 + 14x

Step 1: Multiply  3 with terms inside the bracket

21x+51 > -19 + 14x

Step 2:Subtracting 51 on both sides

21x+51-51 > -19 + 14x-51\\21x>14x-70\\

Step 3: Subtract 14x on both sides

21x-14x>+14x-70-14x\\7x>-70

Step 4: Divide both sides by 7

\frac{7x}{7}>\frac{-70}{7}\\x>-10

Solving the inequality we get: \mathbf{x>-7}

The graph is attached in the figure below.

ValentinkaMS [17]

Answer:  \bigg(-3,\dfrac{1}{2}\bigg)

<u>Step-by-step explanation:</u>

G = (-7, 3)    H = (1, -2)

M_{GH}=\bigg(\dfrac{X_G+X_H}{2},\dfrac{Y_G+Y_H}{2}\bigg)\\\\\\.\qquad = \bigg(\dfrac{-7+1}{2},\dfrac{3+(-2)}{2}\bigg)\\\\\\.\qquad = \bigg(\dfrac{-6}{2},\dfrac{1}{2}\bigg)\\\\\\.\qquad = \large\boxed{\bigg(-3,\dfrac{1}{2}\bigg)}
