Answer:

5 Quarters

5 Nickels

Step-by-step explanation:

Amount of nickels: n

Amount of quarters: q

n = 5 cents

q = 25 cents

n+q=10

5n + 25q =150

n=10-q

Substitute.

5(10-q)+25q=150

50-5q+25q=150

50+20q=150

20q=100

q=5

5 Quarters

5 Nickels

The other question:

Dimes = D

Quarters = Q

d + q = 13

q = 13 - d

10d + 25(13 - d) = 220

Solve this equation.

10d + 325 - 25d = 220

325 - 15d = 220

325 = 220 + 15d

105 = 15d

7 = d

<u>7 dimes </u>

<u>6 quarters</u>

Third question:

11 tickets total = $34

Number of children's tickets = c

Number of adult's tickets = a

c = $2

a = $4

c + a = 11

a = 11 - c

2c + 4(11-c) = 34

2c + 44 - 4c = 34

44 - 2c = 34

44 = 34 + 2c

10 = 2c

5 = c

<u>5 children's tickets</u>

<u>6 adult's tickets</u>

The Keller family's dinner bill is $55.35. This includes an 8% meal tax and a 15% tip on original meal for the server
Arlecino [84]
You find 8% of 55.35  which is 4.42
Then you find 15% of 55.35 which is 8.30
You add them together which equals 12.72
You then subtract 12.75 from 55.35   55.35-12.75=42.63
The original price was $42.63

100+50x=150+30x please answer thi and thank you
Anna [14]

Subtract 100 from both sides

50x = 150 + 30x - 100

Simplify 150 + 30x - 100 to 30x + 50

Subtract 30x from both sides

50x - 30x = 50

Simplify 50x - 30x to 20x

20x = 50

Divide both sides by 20

x = 50/20

Simplify 50/20 to 5/2

<u>x = 5/2</u>

<em>In decimal: 2.5</em>
