Step-by-step explanation:
This is the concept of algebra, the average number of muffins baked by each girl will be given as follows;
Muffins baked by Andrea=h muffins
Muffins baked by Violet =h-8
Average=(Total sum of numbers)/(Number of items)
total sum=h+(h-8)=2h-8
Number of items=2
thus;
average=(2h-8)/2=h-4
the answer in terms of h is (h-4)
Step-by-step explanation:
15^2-12^2
225-144
81
√81=9
21÷9=2.3333(recurring)
2.33333×15=x
X=34.999
or X=35 to 1 d.p
Answer:
length=4
width=30
Step-by-step explanation:
length=x
width=8x-2
(8x-2)*2+2x=68
16x-4+2x=68
18x=72
x=4 (Length)
4*8=32, 32-2=30(width)
