Clayton has saved $5.65 in dimes and quarters. He has 10 more quarters than dimes. How many of each denomination of coins does h
Ksju [112]

Answer: Dimes: 9

Quarters :19

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations using the information given:

He has 10 more quarters than dimes

Q = D +10

Clayton has saved $5.65 in dimes and quarters

0.25 Q + 0.10 D = 5.65

Where:

Q= number of quarters

D= number of dimes

Replacing the value of Q for (D+10) in the second equation:

0.25 (D +10)  + 0.10 D =5.65

0.25D + 2.5 +0.10D =5.65

0.25D + 0.10 D =5.65-2.5

0.35 D = 3.15

D = 3.15/0.35

D=9

Replacing the value of D by 13 in the first equation:

Q= D +10

Q =9 +10 =19

Which input value produces the same output value for the two functions ​
Lady bird [3.3K]

Answer:

Completion to the first table for f(x)=\frac{2}{3} x+7 is {-1, 1, 3, 5}

Completion to the second table for g(x)=2x+16\\ is { -8, -2, 4, 10}

the option is x=-6

Step-by-step explanation:

\frac{2}{3} (-12)+7= -1

\frac{2}{3} (-9)+7=1

\frac{2}{3} (-6)+7=3

\frac{2}{3} (-3)+7=5

2(-12)+16=-8

2(-9)+16=-2

2(-6)+16=4

2(-3)+16=10

Hope this helps and is correct.
