Answer:
74.48 (round down to 74)
Step-by-step explanation:
2% of 76 is 1.52, so the correct reading would be 74.48 (rounded to 74)
to find that 2% of 76 what 1.52, I did 76 x .02 which gave me 1.52. Then I subtracted 1.51 from 76, which gave me 74.48
Equations used:
76x.02=1.52
76-1.52=74.48
<span>number of gallons of gas, x
</span><span>total cost of the gas, y

3.75x <= 12
x <= 3.2
<span>The greatest amount of gas Berto can buy is 3.2 gallons</span>
The original are would be 48.
Since we know that the length and width are two consecutive even integers, we can model them as follows:
Width = x
Length = x + 2
This works because no matter what even number is put in for x, the length will also be even.
Now we know if we subtract 3 from the width, we have a new rectangle that gives us an area of 24 inches. Therefore, our new triangle has the following:
Width: x - 3
Length: x + 2
Area: 24
And we can plug this into the equation.
Length* Width = Area
(x + 2)(x - 3) = 24
x^2 - x - 6 = 24
x^2 - x - 30 = 0
This is not a quadratic that we can factor to show the following:
(x - 6)(x + 5) = 0
This gives us the answers of x = 6 and x = -5. Since a side can't be negative, we throw out the x = -5 and the answer is x = 6.
So if we go back to the original rectangle, we know:
Width = x = 6
Length = x + 2 = 8
Area = 6*8 = 48
