Answer: 14 dimes and 8 quarters

<u>Step-by-step explanation:</u>

dimes ($0.10): x + 6

quarters ($0.25): x

Cost*quantity of dimes + Cost*quantity of quarters = Total value

0.10(x + 6) + x(0.25) = 3.40

0.10x + 0.60 + 0.25x = 3.40

0.35x + 0.60 = 3.40

<u>            -0.60  </u> <u>-0.60 </u>

0.35x             = 2.80

<u>÷0.35            </u>  <u>÷0.35 </u>

      x              = 8

dimes: x + 6   = 8 + 6   = 14

PLEASE HELP ASAP!!! (No links)
marta [7]

Answer:

No it is not a solution

Step-by-step explanation:

To solve this, you should replace your (x,y) with (8,3)- 8 being your x value and 3 being your y value.

So this inequality, your y value is supposed to be bigger than the value of whatever 3x-4 equals.

So, your inequality should be 3>3(8)-4

3*8=24-4=20

So is 3>(greater than)20? No. Which then means that (8,3) is not a solution because it would make the inequality not true.

Hope this helps!
