Answer:
I don't know what the following sentence is:
But D is the equation to represent the situation
and A is what turns out to be his current age.
(If you want more help, on this question please post the following sentence).
Step-by-step explanation:
Let x represent the current age.
15 years from now his age is 3 times his age 5 years ago means we have the equation:
x+15=3(x-5)
(I added x to 15 because we said 15 years in the future)
Let's solve this to see if makes any sense just for fun:
Distribute:
x+15=3x-15
Add 15 on both sides:
x+30=3x
Subtract x on both sides:
30=2x
Divide both sides by 2:
15=x
So this means his current age is 15.
5 years ago his age would have been 10.
15 years in the future his age will be 30.
Is 30 equal to 3 times 10? Yes, it is! The equation does make sense.
Answer:
D,
Step-by-step explanation:
x is the present age of William, 15 years from now is x+15, and that is equal to 3 times 3() the age he had 5 years ago (x-5)., the equation is x+15=3(x-5)
