511 = -7 (10x – 13)<br> steps

PilotLPTM [1.2K]

Answer: $x=-6$

<u>Simplify both sides of the equation</u>

<u></u> $511=(-7)(10x)+(-7)(-13)(Distribute)\\511=-70x+91$ <u></u>

<u></u>

<u>Flip the equation</u>

<u></u> $-70x+91=511$ <u></u>

<u></u>

<u>Subtract 91 from both sides</u>

<u></u> $-70x+91-91=511-91\\-70x=420$ <u></u>

<u></u>

<u>Divide both sides by -70</u>

<u></u> $-70x/70=420/-70\\x=-6$ <u></u>

There are 12 coins ; dimes and quarters. The number of dimes is 2 more than the number of quarters.

galben [10]

Answer:

D. $1.95

F. $3

Step-by-step explanation:

dimes: x + 2

quarters: x

x + 2 + x = 12

2x + 2 = 12

2x = 10

x = 5

dimes: x + 2 = 5 + 2 = 7

quarters: x = 5

Total value: (7 * .10) + (5 * .25) = $1.95

_____

dimes: x

quarters: 2x

x + 2x = 15

3x = 15

x = 5

dimes: x = 5

quarters: 2x = 2(5) = 10

Total value: (5 * .10) + (10 * .25) = $3
