Answer: Yes, you can find the original price of the phone case. The phone case was $560
Step-by-step explanation:
42.00 divided by 25% is $168
$168 divided by 30% is $560
(12)(20)= 240
The answer is going to be B. 240 sq ft
10-7x=2-8x
We move all terms to the left:
10-7x-(2-8x)=0
We add all the numbers together, and all the variables
-7x-(-8x+2)+10=0
We get rid of parentheses
-7x+8x-2+10=0
We add all the numbers together, and all the variables
x+8=0
We move all terms containing x to the left, all other terms to the right
x=-8
Answer:
y = -1/2x + 13/2
Step-by-step explanation:
The slope of a line that is perpendicular to a line will be a negative reciprocal. When you rewrite 2x-7=8 into slope-intercept form, you get y=2x-8. The negative reciprocal of the slope 2x is -1/2x. There is only one option with this slope. If you're still not sure then you can use a graphing calculator to check this. An online one would be desmos
