ty ten years ago?
1 answer:
Answer: The answer is 500,000.
Step-by-step explanation:
100% - 30% = 70%
x => 100%
350000 => 70%
x = 350000*100% / 70%
x = 500000

Answer:
Width: 90m
Length: 120m
Step-by-step explanation:
Width = 3/4x
Length = x
2(3/4x) + 2x = 420m
6/4 x + 2x = 420m. (6/4 + 2 = 7/2)
7/2x = 420m
7x = (420)*(2)
x = 840/7 = 120
Width = (120)*(3/4) = 90
Length: 120
2(90)+2(120)= 420m
1/5n - 12 = -7
or you can say
n/5 - 12 = -7
then if you solve...
n/5 - 12 = -7
+12 +12
n/5 = 5
times 5 on each side
n = 25
