Answer:
37.5 +25.5
Step-by-step explanation:
37.5+25.5 = 63
37.5-25.5 = 12
Answer:
First find the area 72*63
A=4536
Then find the area 12*12
A=144
Then divide 4536/144
You would need 31.5 12 by 12in covers to decorate the rectangular region
As for the 6 by 6
You would need 126 album covers
As for the 9 by 9
You would need 51 covers
And as for the 15 by 15
You would need 20.6 covers
Answer:
x=1 y=7
Step-by-step explanation:
−5x+2y=9
y=7x
Substitute the second equation into the first
-5x +2(7x) = 9
Distribute
-5x +14x = 9
Combine like terms
9x=9
Divide by 9
9x/9 =9/9
x= 1
Now find y
y = 7(1)
y = 7
