M<7 + m<8 + m<9 = m<EAD
31 + 22 + m<9 = 102
53 + m<9 = 102
m<9 = 49
Answer:
I think it’s C
Step-by-step explanation:
Answer:
a=31
Step-by-step explanation:
1/2(a-9)=11
a-9=22
a=22+9
a=31
Since you have the length and the area, you can assume the width
1496/44 = Width Because Area = L * W
Width = 34
So this is a ratio problem
44/11 = ratio
So, the ratio is 4:1
So since we have the width, we can divide the width of the school banner by 4 because of the scale
34/4 = 8.5 = width of the sign
The area of the sign is 8.5*11 = 93.5
and the perimeter is just that,
8.5 * 2 + 11*2 = 39
Perimeter = 39 inches
Area = 93.5 inches²
