Answer:
5x + 9
Step-by-step explanation:
when you dont know a number you are supposed to use a letter and when you want to multiply a letter and a number you put them next to each other then for this specific question you add 9
7/8 = x/48
Cross multiply, which is: a/b = c/d ⇒ ad = bc
After cross multiplying, we get:
8x = 7(48)
8x = 336
Divide 8 on both sides
x = 42
Your final answer is B. 42<span>.</span>

Step-by-step explanation:
<em><u> </u></em><em><u>no </u></em><em><u> </u></em><em><u>solution </u></em><em><u> </u></em><em><u>is the solution, if any, to the inequality 10x1207</u></em>
Answer:
10x^3+13x^2-15x-67
Step-by-step explanation:
First you distribute- 10x^3+25x^2-40-12x^2-15x-27
you distribute the 5 through then the negative 3 through
Then you combine like terms
10x^3+13x^2-15x-67
Then that is just your answer after you add the ones with the squared together and the ones with no variables together
