Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The equation will be...
I don't know if you need to solve it but here you go anyways...
Let the width be w, then the length is 2w - 2.5.
Perimeter = 2(length + width)
40.6 = 2(2w - 2.5 + w) = 2(3w - 2.5)
3w - 2.5 = 40.6/2 = 20.3
3w = 20.3 + 2.5 = 22.8
w = 22.8/3 = 7.6
Therefore, width is 7.6 cm.
Answer:
b = -12
Step-by-step explanation:
First isolate b by subtracting 2 from both sides: b/4 = -3
then multiply both sides by 4 to find b: b = -12
Answer:
5780
Let’s say her daughter is the 9 of the ratio. To find one part, you must divide 3060 by nine which gives you 340. That is one part. You can then multiply that by 8 to find the amount of money her son gets, which is 2720. Then you just add 3060+2720 which gives you 5780.
