1. Let hardcover books = X
Paperback books would be 4x -3 ( 3 less than 4 times)
Now you have:
X + 4x-3 = 447
Simplify:
5x - 3 = 447
Add 3 to each side:
5x = 450
Divide both sides by 5:
x = 450/5
x = 90
He has 90 hardcover books.
2. 300 miles / 25 miles per gallon = 12 gallons of gas.
12 gallons x $$ per gallon = $48 dollars
3. Subtract base pay from total:
1916 - 800 = 1,116 worth of commissions.
Divide commissions by percentage:
1116 / 0.09 = $12,400 total sales.
4.
Find the median of the heights: 65-50 = 15. 15/2 = 7.5
Median = 50+7.5 = 57.5
The equation would be |h-57.5| < 7.5
Answer:
6
Step-by-step explanation:
9/1 × 2/3
(9 × 2 = 18)
(1 × 3 = 3)
18 ÷ 3 = 6
Answer:
Slope, Angle, & Distance:
Slope: 0.5625
The slope of the line connecting (15, 20) and (-1, 11) is 0.5625
Slope (m): 0.5625
Angle (θ): 29.3578°
Distance: 18.3576
Δx: 16
Δy: 9
Slope Intercept Form:
(y = mx + b)
y = 0.5625x + 11.5625
Step-by-step explanation:
Steps to Find Slope
Start with the slope formula
m=
(y2 - y1)
(x2 - x1)
Substitute point values in the formula
m=
(11 - 20)
(-1 - 15)
Simplify each side of the equation
m=
(11 - 20)
(-1 - 15)
=
-9
-16
Solve for slope (m)
m=0.5625

n = 66
Step-by-step explanation:
you can make a proportion 3/99 = 2/x
99 * 2= 198
3 * x = 3x
so the equation would be 198 = 3x
than do 198 ÷ 3 on ur calculator
so x (or n in this context) would equal 66
