The answer is 42.5$. 30% off 75=52.5. 52.5-10=42.5
Answer:
Step-by-step explanation:
When x = 3, y = 13
When x = 5, y = 37
Subtract both y-values to find the change:
37 - 13 = 24
Average of the change:
= 12
Step-by-step explanation:
if one pump = x
the other pump = 2x
therefore
x + 2x = 8 minutes
3x = 8 minutes
Divide through by 3
x = 8/3 minutes
converting it to seconds
x = 8/3 * 60
x = 160 seconds
therefore
the first pump = 2x = 2 * 160 = 320 seconds
the second pump = x = 160 seconds
Well think of it this way
which is bigger 21 or 40?
40 correct
this rule applies to decimals as well, as long as they are not a negative integer
this number is not negative, and therefore, the number that looks bigger actually is bigger
and we know that 4 is bigger than 2, and since there both are written in the hundredth place of the decimal, we can safely conclude that 0.04 is bigger than 0.021
