X = larger number, y = smaller number
x + y = 75
x = 3y + 11
3y + 11 + y = 75
4y + 11 = 75
4y = 75 - 11
4y = 64
y = 64/4
y = 16 <=== ur smaller number
x = 3y + 11
x = 3(16) + 11
x = 48 + 11
x = 59...ur larger number
Answer:
Step-by-step explanation:
This basically the general formula of Slope point form for the linear equation.
Defining the slope of the line and a point on the line (not actually the y-intercept)
(x1,y1) = Point on the line
m = slope on the line
This is going to require a good bit of division. I am going to turn the mixed fractions into improper fractions. Remember that to divide fractions, you take the 2nd fraction, flip it, and multiply.
First (2 1/2)/(1/4) = (5/2)(4) = 20/2 = 10
Next, 3/(1/4) = 3(4) = 12
Lastly, (3 1/4)/(1/4) = (13/4) x 4 = 52/4 = 13
This means we need 10 rows of 12, 13 high. 10(12)(13) = 1560 cubes.
