Answer:
-10a^9
Step-by-step explanation:
Since they have the same variable and exponent, just add them together.
x= the number of girls competing
x+16=the number of boys competing
The equation to find the number of boys and girls competing would be:
x+(x+16)=1000
First, combine like terms:
2x+16=1000
Subtract 16 from both sides.
2x=984
Divide both sides by 2:
x=492
We know now that the number of girls competing is 492. To find the number of boys competing, you simply have to add 16 to 492.
492+16=508
There are 508 boys competing and 492 girls competing.
I hope this helps :)
I think the answer is A. (7)(5x)(10)
