Answer:
11 inches
Step-by-step explanation:
A rectangle's perimeter can be found using:
p=2l+2w
We know that the perimeter, p, is 58, and the length/height is 18. Therefore, we can substitute those values in
58=2(18)+2w
Multiply 2 and 18
58=36+2w
Since we want to find the width, we need to get w by itself. First, subtract 26 from both sides
58-36=36-36+2w
22=2w
Since w is being multiplied by 2, divide both sides by 2. This will cancel out the 2, and leave w by itself.
22/2=2w/2
11=w
So, the width is 11 inches
Answer:
36 + 3b = 117
Step-by-step explanation:
36 is the one specialized cake he sold.
3 is the cost and b is how many it represents
117 is your total, so we piece it together.
36 + 3(b) = 117
B becuase you treat the inequality like a squiggly line problem and you add 2 to both sides to isolate the variable. And since it’s sign is less than or equal to you have a closed dot and you point the arrow going less than 5
