Answer:
2
Step-by-step explanation:
Subtract 1 from 7, and then divide 6 by 3.
Divide 252 by 21.
21 times 12 = 252
12 is 9 units shorter than 21.
so the answer is 12 inches by 21 inches
you work backwards from the area
area = width times length
a = wl
we know w is 9 units shorter than the length
so now we have the equation 252=(l-9) times l
plug in 21 for l and then solve there is your answer.
Answer:
1 17/40
Step-by-step explanation:
5/8+4/5
We need to get a common denominator of 40
5/6 * 5/5 = 25/40
4/5*8/8 =32/40
25/40 + 32/40 = 57/40
57/40 = 40/40 + 17/40 = 1 17/40
