A store is having a sale where school supplies are 30% off their original price. A backpack is on sale for $11.20. What was the original price for the backpack?

Answers

To find the original price, you could use a variable to represent the original price in this equation;

Let p represent the original price

.70 × p=11.20

to solve this, we'd isolate the variable (p) 

p=11.20 ÷.70

p=16

The original price was $16

If you draw a line diagonal from one top corner to the opposite bottom corner you will have made 2 triangles. Then you can use the Pythagorean theorem to figure out the diagonal measure (or hypotenuse of the triangle.c squared=15 squared + 27 squaredc squared= 225+729c squared= 954c= square root of 954c=30.88I would round that up to 31 inches
B.31 inches, I got this from 30.88 and I rounded.
1st. Draw a line diagonal from one top corner to the opposite bottom corner(you will have 2 triangles)
2nd.Pythagorean theorem to figure out the  hypotenuse of the triangle.
 c^2=15^2 + 27^2 c^2= 225+729 c^2= 954 c= square root of 954 c=30.88, aka 31 inches.

When using elimination to solve 2x-3y = 4 7x+ 6y = -1 what would be a possible first step? A 4x – 6y = 8 7x + 6y = -l B x = 3/2y + 2 7x + 6y = -1 C 2x -3y = 4 x = -6/7y – 1/7 D y = 2/3x – 4/3 7x + 6y = -1

Answers

A because you have to multiply the problems to even in out 
(2x-3y=4) x2
(7x+6y=-1) x1

4x – 6y = 8
7x + 6y = -l
