Answer:
US$ 1,084.80 were raised from the raffle tickets and US$ 1,035 are the profits after paying the prizes.
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Number of raffle tickets sold = 1,356
Cost of each raffle ticket = US$ 4/5
Number of prizes = 6
Cost of each prize = US$ 8 3/10
2. How much money was raised from the raffle tickets?
For easier calculation, let's convert the fraction numbers to decimal numbers:
Cost of each raffle ticket = US$ 4/5 = US$ 0.80
Cost of each prize = US$ 8 3/10 = US$ 8 + 0.30 = US$ 8.30
Now, we use this formula to calculate how much money was raised and the profits:
Profits = (Number of tickets sold * Cost of each ticket) - (Number of prizes * Cost of each prize)
Replacing with the real values, we have:
Profits = 1,356 * 0.80 - 6 * 8.30
Profits = 1,084.80 - 49.80
Profits = 1,035
US$ 1,084.80 were raised from the raffle tickets and US$ 1,035 are the profits after paying the prizes.

Answer:. If the Area is 177, it should have been given in square centimeters.
If one side is 13 cm, the other side is about 13.6cm.
If one side is 11 cm, the other side should be about 16.1 cm. Even the choice is incorrect!
A/x = w
Step-by-step explanation: to find a side when the Area is given, divide the Area by the length or width given.

Elena bought 320 tropical fish for a museum display. She bought 7 times as many triggerfish as parrotfish. How many of each type of fish did she buy?
Which is a system of equations to model the problem if x represents the number of parrotfish Elena bought and y represents the number of triggerfish she bought?
A.
x + y = 320
y = 7x
B.
x + 7y = 320
y = 7x
C.
x – y = 320
y = 7x
D.
x + y = 7
y = 320x
2. Michael and Kathryn bowl together and their combined total score for one game was 425 points. Michael’s score was 70 less than twice Kathryn’s. What were their scores?
Which is a system of equations to model the problem if x represents Kathryn’s score and y represents Michael’s score?
A.
x + y = 70
y = 2x – 425
B.
x – y = 425
y = 2x – 70
C.
x + y = 425
y = 2x – 70
D.
x + y = 425
y = 2x + 70

explain how u got the answer
#1
3 1/2 +5 2/3
you would want to get these to have common denominators so you would multiply them, the lowest number they both can go into is 6 so you would have both of them go into that number. And they would equal
3 3/6 + 5 4/6 = 8 7/6
You can reduce this down to
9 1/6
__________________________________________________________
#2
2/5 (3/4)
you want to remove the parentheses so it would be
2/5 x 3/4
Then you will cross cancel the numbers (2 and 4)
1/5 x 3/2
then you want to multiply the fractions, and it would be.
3/5x2
and you multiply once again for your final answer
3/10
Answer #1: 9 1/6
Answer #2: 3/10
