Answer:
Wendell is 24 years old.
Step-by-step explanation:
First write an equation to represent the situation.
x=Maggie's age
x+(3x-3)=33
Then solve for x
x+3x-3=33
4x-3=33
4x-3+3=33+3
4x=36
4x/4=36/4
x=9
Then solve for Wendell's age
y=Wendell's age
y=3x-3
y=3(9)-3
y=27-3
y=24
Wendell is 24 years old.
Answer:
A. $258.00
Step-by-step explanation:
There are 12 months in a year so you will simply have to multiply $21.50 by 12
21.50 x 12
258
You have to compute the prices of the two alternatives after
deducting discount based on the different percentage given.
First alternative: $19.99 – ($19.99 x 20%) = $15.99
Second alternative: $17 – ($17 x 10%)
= $15.30
Therefore, the alternative where
there will be a 10% off on the original price of $17 for a book is cheaper.
Answer:
- m = -3/4
- y-intercept = 399
- slope-intercept equation: y = -3/4x + 399
Step-by-step explanation:
It can be easiest simply to solve the equation for y.
3x + 4y = 1596
4y = -3x + 1596 . . . . subtract 3x
y = -3/4x + 399 . . . . divide by 4
From this equation in slope-intercept form you can read the slope as -3/4 and the y-intercept as 399. You already know the equation.
