11. 180-73 = 107
10. 180-107=73
12. 180-73=107
13. 5x + 20 + B = 180 -> B = 180 - 20 - 5x and 3x+66 + B = 180 -> 3x+66+ (180 - 20 - 5x) = 180 -> 222-180 = 2x -> x = 21
14. ABC = 5x + 20 = 5*21+20= 125
15. ABE = 3x+66 = 3*21+66 = 129

Peppy Pets charges a flat fee of $15 plus $3 per hour to keep a dog during the day. Happy Hounds charges a flat fee of $21 plus

stich3 [128]

Answer: d) 3 hours.

Step-by-step explanation:

Let x be the required number of hours for which the total fee charged by the companies the same.

Given: Peppy Pets charges a flat fee of $15 plus $3 per hour .

So Total charge = 15+3x ( in dollars)

Happy Hounds charges a flat fee of $21 plus $1 per hour.

So Total charge = 21+x ( in dollars)

When the total charge for both companies are the same, then

$15+3x=21+x\\\\\Rightarrow\ 3x-x=21-15\\\\\Rightarrow\ 2x=6\\\\\Rightarrow\ x=3$

Hence, the correct option is d) 3 hours.

Wendy paid 6.29*3.74 for swiss cheese and 6.29*1.34 for provolone cheese.

klasskru [66]

If the raffle has 200 tickets total, then about 50 tickets will be in the dining out raffle.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

From the diagram:

Percentage of dinner out = 65% - 40% = 25%

For 200 total tickets:

Number of dinning out raffle = 25% of 200 = 0.25 * 200 = 50 ticket

If the raffle has 200 tickets total, then about 50 tickets will be in the dining out raffle.
