P = 2(L + W)
P = 120
W = 20
120 = 2(L + 20)
120 = 2L + 40
120 - 40 = 2L
80 = 2L
80/2 = L
40 = L
check..
120 = 2(40 + 20)
120 = 2(60)
120 = 120 (correct)
so the length of the garden (L) = 40 yds
Answer:
x = 4/7
Step-by-step explanation:
5/3 x = 20/21
Multiply by 3/5 on each side to isolate x
3/5 *5/3 x = 20/21 * 3/5
x = 20/21 * 3/5
Rewriting the right hand side
x = 20/5 * 3/21
x =4 * 1/7
x = 4/7
Well lets see A, B and D are too large in the parenthesis that the numbers outside of the parenthesis will use to multiply considering 42 + 30.
6(7 + 5)
6(12)
72
Answer:
The answer all together would be 5 minus n.
Step-by-step explanation:
a negative and a positive equals a positive so -1/2 + 1 1/2 would equal 2 and 2 + 3 equals 5. Then, the remaining numbers are 5 and n. The final answer is 5 minus n because n is unknown.
You would have 14/6ths. Work: 7/2x3=21/6, 21/3=7, 7x2=14.
