1/4(r - 5/2) = 1/8
Divide both sides by 1/8 :0
2(r - 5/2) = 1
r - 5/2 = 1/2
r = 1/2 + 5/2 = 6/2

r = 3 Answer

\dfrac{1}{4}(r - \dfrac{5}{2}) = \dfrac{1}{8}

The LCD of both fractions is 8, so multiply both sides by 8.

8 \times \dfrac{1}{4}(r - \dfrac{5}{2}) = 8 \times \dfrac{1}{8}

2(r - \dfrac{5}{2}) = 1

Distribute the 2 on the left side.

2r - 5 = 1

2r = 6

r = 3

Answer:

Answer: Janet is 16, and David is 11.

Step-by-step explanation:

Let the ages be j and d.

j = d + 5

j + d = 27

Substitute d + 5 for j in the second equation.

d + 5 + d = 27

2d + 5 = 27

2d = 22

d = 11

Substitute 11 for d in the first equation.

j = d + 5

j = 11 + 5

j = 16

Answer: Janet is 16, and David is 11.

Anita and Joelle bowled together and their combined total score for one game was 425 points. Anita’s score was 40 less than twic
wariber [46]
Call Anita's score "y" and Joelle's score "x".

1) "<span>their combined total score for one game was 425 points"
</span>Therefore x+y=425

2)"Anita’s score was 40 less than twice Joelle’s." 
Therefore y=2x-40

Substitute:
x+2x-40=425

Solve:
3x=465
x=155

Backsubstitute:
y=2x-40
y=2(155)-40
y=270
