Answer 1

72 quorters
3 dimes

Answer 2

We can write two equations and solve.

0.25q + 0.10d = 18.30
q + d = 111

Where q = quarters and d = dimes.

Answer 3

Here's the graph..what's the solution? @literally.kaylaa

Answer 4

@Algebruhh Don't give out answers, plus your answer is wrong. 72 + 3 = 75 coins total..it says there are 111 coins total.

Answer 5

The solution to the system of equation is (48, 63). (quarters, dimes)

So how many quarters and dimes are there? @literally.kaylaa

Answer 6

you two are making it too hard. 4 quarters equal a dollar. So you take 18 x 4 = 72. Then 3 dimes makes up the extra 30 c
