If 9 more than 2 times a number is 13 what is the number?

The algebraic expression for this would be 9 + 2x = 13

Step-by-step explanation:

Step 1: Simplify both sides of the equation

2x + 9 = 13

Step 2: Subtract 9 from both sides.

2x + 9 - 9 = 13 - 9

2x = 4

Step 3: Divide both sides by 2.

2x/2 = 4/2

x = 2

Or, you can use a diffrent way (which I simply prefer).

Step 1: Subtract 9 from 13.

13 - 9 = 4

Step 2: Divide the number 4 by 2

4 ÷ 2 = 2

x = 2

Either way will get you the answer, hope this helps!

answer: check all that apply, where the options?

step-by-step explanation:

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
