Answer:
Step-by-step explanation:
Add and then multiply the one left
20% = $180
100% = x
20x = 180 × 100
20x = 18,000
x = 900
The original price is $900
is it 11/8 or 1 and 1/8?
if it is 11/8 divide 11 by 8, 11/8 = 1.375
if it is 1 and 1/8 divide 1 by 8, 1/8 = 0.125 then add it to the 1
so 1 and 1/8 = 1.125
Answer:
7x, 4y
Step-by-step explanation:
terms are numbers with variables in expressions. usually able to count because + and - split them
Answer:
(x+1) (x-1) (x+2) (x-2)
Step-by-step explanation:
<u>Let u = x^2</u>
= u^2 - 5u + 4
<u>(Factor u^2 - 5u + 4)</u>
= (u-1) (u-4)
<u>Substitute back u = x^2</u>
= (x^2 -1 ) (x^2 - 4)
<u>Factor x^2 - 1 and x^2 -4</u>
= (x+1) (x-1) (x+2) (x-2)
