Answer:
Attached in file. I did this on paper, apologies if the PDF is blurry.
Hmm the closes one i could get is C Because it's the only one near 4,125
Hope that help :D
First, we know (D is dad, J is Jill) that D+J=50.
Second, in 5 years D will be 3 times as old so
(D+5)= 3*(J+5)
Moving on, if we know D+J=50 then D=(50-J) is true.<span>Taking that relationship and substituting for D in the other equation, it becomes
50 - J + 5 = 3 * (J + 5)
Then, it becomes </span>50 - J + 5 = (3 * J) + (3 * 5)
Then, 55 - J = (3 * J) + 15
Then, 55 - 15 = (3 * J) + J
<span>which becomes 40 = 4*J</span>
Answer:
it is b because I did the math and got that
You will have to cross multiply and also distribute the fractions like this:
2/3 of 3/8 times 16
so 3/8 times 16 is 6
Now take 2/3 of 6 and youll end up with 4! :)
