Here is an equation 2x + 9 = -15. Write three different equations that have the same solution as 2x + 9 = -15. Show or explain how you found them.

To find those equations we can do any multiplication or division of both sides of the equation:

Examples:

2x + 9 = -15              | · 2

4x + 18 = -30

2x + 9 = -15              | · (-1)

-2x - 9 = 15

2x + 9 = -15               | ÷ 2

x + 4.5 = -7.5

There is the same solution: x = -12.

The three different equations (x = -12, 2x = -24, and -2x - 9 = 15) that have the same solution as the original equation 2x + 9 = -15.

To find three different equations that have the same solution as 2x + 9 = -15, we can manipulate the given equation using algebraic operations. The goal is to preserve the solution while changing the form of the equation. Here are three different equations:

Subtract 9 from both sides of the equation:

2x + 9 - 9 = -15 - 9

2x = -24

Divide both sides of the equation by 2:

(2x)/2 = (-24)/2

x = -12

This equation, x = -12, has the same solution as 2x + 9 = -15.

Multiply both sides of the equation by -1:

-1(2x + 9) = -1(-15)

-2x - 9 = 15

This equation, -2x - 9 = 15, has the same solution as 2x + 9 = -15.

By applying these transformations, we obtained three different equations (x = -12, 2x = -24, and -2x - 9 = 15) that have the same solution as the original equation 2x + 9 = -15.

HELP PLEASE!!! Which equation can be used to calculate the area of the shaded triangle in the figure below?

A rectangle is shown with a width of 8 ft and a length of 14 ft. There is a diagonal line through the rectangle, and the bottom half is shaded in grey.

2(14 + 8) = 44 square feet
1 over 2.(14 + 8) = 11 square feet
2(14 × 8) = 224 square feet
1 over 2.(14 × 8) = 56 square feet

For 1–3, find the area of each circle. Use 3.14 for π. Round to the nearest tenth if necessary. a circle with radius 48 mm

Which expression completes the equation?

Recycling paper is the best way to protect trees. Recycling prevents trees from being cut down and used for paper and other products. According to the Green Center, recycling one ton of paper helps save 17 trees. If everyone in the United States recycled just a small portion of their newspapers, we could save 25 million trees. People should recycle paper and use recycled products whenever they can to save our forests.

Which statement expresses the author’s claim?

Recycling saves trees.
Trees are important.
Recycling one ton of paper saves 17 trees.
