First multiply 5x to both sides. Then subtract 7 to get 5=5x, leading to the answer of x=1
Answer:
Step-by-step explanation:
<u>Triangle area formula:</u>
- A = bh/2, where b- base, h- height
<u>We have:</u>
<u>The area is:</u>
Correct choice is C
If Jeff is x years old, Ben is x - 9 years old.
Ten years later, Jeff would be x + 10 years old and Ben would be (x - 9) + 10 years old.
x + 10 + (x - 9) + 10 = 67
2x + 11 = 67
2x = 56
x = 28
Jeff is 28 right now and Ben is 19 right now.
I’m pretty sure it would be B.
