Randy, Sandy and Todd are my cousins and their combined age is 87 years. Randy is four times as old as Sandy, but Todd is actual
NISA [10]

Answer:

Randy is 48 years old

Sandy is 12 years old

Todd is 27 years old

<em></em>

Step-by-step explanation:

Given

Represent their ages with the first letters of their names:

R + S + T = 87

R = 4 * S

T = 15 + S

Required

Determine their individual ages

We'll solve the above equations using substitution method of simultaneous equations

Substitute 15 + S for T and 4 * S for R in R + S + T = 87

This gives:

4 * S + S + 15 + S = 87

4 S + S + 15 + S = 87

Collect Like Terms

4 S + S + S = 87 - 15

6S = 72

Divide through by 6

S = 72/6

S = 12

<em>This implies that Sandy is 12 years old</em>

Substitute 12 for S in R = 4 * S and  T = 15 + S

R = 4 * 12

R = 48

T = 15 + 12

T = 27

<em>This implies that Randy is 48 years old and Todd is 27</em>

Please help with my math. Will give brainliest
Sav [38]
You will have to multiply 80 and the percentage. First you will have to change the percentage to a decimal which in this case it will be 0.39 ( for the first one) so then multiply it so it will be 80x0.39=31.2 and you will do the same with the others just replace the numbers with the one that you are doing hope this helps.
