Answer is 42. 70 x .4 =28. 70-28
The correct unit price would be $1.08 per pair of gloves. What the contractor didn't notice was it was 7 <em>dozen</em> pairs of gloves, not just seven pairs. If it had been seven pairs, she would have been correct, but it was actually 84 pairs of gloves. She needed to divide 103.32 by 84 rather than 7.
Step-by-step explanation:
x³ + 10x² + 25x
= x(x² + 10x + 25)
= x(x + 5)².
the correct answer would be:
A) (x, y) → ( x + 1, y + 2); (−2, 6)
To find the answer first we will multiply to see how much the books cost. Then we will subtract 50 by the amount of money she has to pay. Then we will check our work to makes sure we are %100 right. Lets do it:-
Lets multiply:-
10 × 2 = 20
So, 10 books cost 20m.
Lets subtract:-
50 - 20 = 30
So she gets 30m in chage.
CHECK OUR WORK:-
30 + 20 = 50
We were RIGHT!!!
So, Coley would receive 30m (B) 30m) in change is she pays with a 50 dollar bill.
Hope I helped ya!!
