BRAINLIEST PLS HELP ASAP!!!

Mathematics
1 answer:
andrew11 [14]3 years ago

Answer:

fourth option

Step-by-step explanation:

let t be tennis balls and g be golf balls, then

5t + 3g = 70 → (1)

2t + 5g = 85 → (2)

Multiplying (1) by 5 and (2) by - 3 will eliminate g

25t + 15g = 350 → (3)

- 6t - 15g = - 255 → (4)

Add (3) and (4) term by term to eliminate g

19t = 95 ( divide both sides by 19 )

t = 5

Substitute t = 5 into either of the 2 equations and solve for g

Substituting into (1)

5(5) + 3g = 70

25 + 3g = 70 ( subtract 25 from both sides )

3g = 45 ( divide both sides by 3 )

g = 15

Thus

$5 for tennis balls and $15 for golf balls
