10x + 15 = 20 so 10x = 20 <span>- 15 =5, and 10x=5 means x=5/10=1/2
</span>
A=4/5. that is equal to a=24/30
b=5/6. b=25/30
to equal them. so a=b? is 24/30=25/30
5*6 and 6*5
4*6 and 5*5

Answer:
$2.70
Step-by-step explanation:
Cost price = $6
Mark up percentage = 45%
Mark up amount = 45% × $6
= 0.45 × $6
= $2.70
Selling price = Mark up + cost price
= $2.70 + $6
= $8.70
Jermaine sells the shirts for $8.70 and makes a profit of $2.70.
The answer is 2k^2 - 7k - 4 because 2k x k is 2k^2 and 2k x (-4) is -8k and 1 x k is k and 1 x (-4) is -4. So then you would get 2k^2 - 8k + k - 4 which simplifies to 2k^2 - 7k - 4 which is your answer.
