Somebody me quickly. i don't understand. answer a, b, & c quickly. you! p. s show me how you got the answers

Hello! I can help you with this!

a. Okay. So Reese has money to buy 115 cm of framing, with the length being 18.5 cm long. The formula would be written like this: 115 = 2(18.5) + 2w.

b. Now, let’s solve the problem. 18.5 * 2 is 37. 115 - 37 is 78. The width could be 78 centimeters or less. In inequality form, it would be written as this: w <= 78.

c. Now, graph the solution by writing a few numbers on the number line. Counting by 2’s, write the even numbers 70-86 on the number line. Put a closed circle point on 78, and then draw the line to the left. Going left means numbers are smaller and a closed circle means the equation is less than or equal to. The number line interprets that the width for both sides can total 78 centimeters or less.

If the diameter is 8 than the radius is 4 because 2r or 2*radius equals the diameter. 4*2=8. 8/2=4.
