Answer:
<u><em>Each notebook costs $1.25</em></u>
Step-by-step explanation:
We'd have to add back the $6.00 coupon to the original price which would now be $11.25.
After getting the original price we now have to divide the price by 9, because of the 9 notebooks you've purchased.
Therefore, the price of $11.25 divided by the 9 notebooks would cost 1.25 each.
Yes it is. When you simplify the girls ratio( 12:30 by 6)you'll get 2:5. When you simplify the boys ratio( 16:40 by 8)you'll get 2:5. So it is the same ratio.
The GCF of 7 and 14a is 7, so the factors are:-
7(1 + 2a)
( 4,20)is the correct answer
10x⁴ and 6w³
1) We see no the same letters in both expressions, so we will need to include all letters in the final answer. x⁴w³
2) number part
10 = 2*5
6=3*2
We need 2*3*5=30 (we need 2 only one times, because we have 2 only one time in each of the numbers).
3)The least common multiple
2*3*5x⁴w³ = 30x⁴w³
Answer is 30x⁴w³.
