Answer:
yes, contradiction
Step-by-step explanation:
4x+8=2x+7+2x-20
4x+8=2x+2x+7-20
4x+8=4x-13
This equation is invalid the right and left.
To answer this, we need to find the average/mean, which is 27+3+2+25+5, witch gives a total of 62. then we need to divide it by the number of numbers, which there are 5. The answer is 12.5, which is the mean.<span />
$21.21 × 6 = $127.26
$127.26 ÷ 7 = $18.18 cost of 1 pillow at Jenson's.
You multiply the cost of the pillow at Harrison's, $21.21, by the amount of pillows you can buy at Harrison's, 6.
Then divide the answer by the amount of pillows you can buy at Jenson's, 7. The final answer is the cost of 1 pillow at Jenson's.
Answer:
6 ?
Step-by-step explanation:
4.
b^-2-x^-2/b^-1+x^-1
b^-2/b^-1=b^-1
x^-2/x^-1=x^-1
As a result, the simplest form is:
b^-1-x^-1. Hope it help!
