Answer:
30%
Step-by-step explanation:
Original price: $
76
Discount percentage:
30%
Discount:
$22.80
Final Price:
$53.20
Discount = Original Price x Discount %/100
Discount = 76 × 30/100
Discount = 76 x 0.3
You save = $22.80
Final Price = Original Price - Discount
Final Price = 76 - 22.8
Final Price = $53.20
The one mistake is -27-10 they put -17 as the answer but it is actually -37.
It is suppose to be:
8x-27-10-6x=15
Rephrase it: 8x-6x-27-10=15
Combine like terms: 2x-37=15
add 37 to each side of the equal sign
(which cancels out the -37): 2x=52
then divide the two numbers by 2: 2x/2=52/2
which then gives you x=26...
you can plug in 26 where you see x in the equation to check your work
Answer:
angle x is 86
angle y is 38
Step-by-step explanation:

Answer:
Step-by-step explanation:
To write a linear inequalities we use the same guidelines as linear equations. They are written in the form, and or with any other inequality signs.
One line has y-intercept 2 and slope is -5/1 (down 5 and over 1).
This means the equation is
.
Test a point not on the line to determine the direction of the inequality sign.
(0,0)
This is true but not the equation becasue (0,0) is not shaded.
The other line has y-intercept -4 and slope 3/1 (up 3 and over 1).
This means the equation is
.
Test a point not on the line to determine the direction of the inequality sign.
(0,0)
This is false and the equation since (0,0) is not in the shaded portion.
