Let x = the number
3.5x = x + 0.5
3.5x - x = 0.5
2.5x = 0.5
x = 0.5/2.5
x = 0.2
therefore the number is 0.2
Answer:
72 inches
Step-by-step explanation:
The given relationship is ...
water = snow/12
Filling in the given information and solving for the unknown, we have ...
(6 in) = snow/12
12(6 in) = snow = 72 in
It takes 72 in of winter snow to accumulate 6 in of water in the soil.
2x - 3*(6x + 11) = 7
-16x + 33 = 7
-16x = -26
x = 13^8 or 1.625
Answer:
Step-by-step explanation:
2*5 = 10
3*5 = 15
The thing you should check is to see if the ratio of the length and width remains the same.
original length 2
============ = ====
original width 3
New length 10
========= = ====
New width 15
But 10 / 15 is the same as 2/3 so the original ratio of 2/3 is not destroyed.
