1)
First box: -10
Second box: -2
Plug in the corresponding numbers to the corresponding boxes:
[(-10)/(-2)]/5 = 1
Simplify. First, solve the bracket. Note that when you divide two negative numbers, the answer will be positive.
(-10)/(-2) = 5
Next, divide the brackets:
[5]/5 = 1
1 = 1 (True)
2)
First box: -5
Second box: -3
Plug in the corresponding numbers to the corresponding boxes:
[5 - (-5)]/[(-3) + 8] = 2
Simplify. First, solve the brackets, then divide:
[5 - (-5)] = [5 + 5] = 10
[-3 + 8] = [8 - 3] = 5
Divide:
10/5 = 2
2 = 2 (True)
3) Use the last two numbers:
First box: -11
Second box: -4
Plug in the corresponding numbers to the corresponding boxes:
(-([-11]) x 2)/(6 + [-4]) = 11
-(-11 x 2)/(6 - 4) = 11
-(-22)/(2) = 11
22/2 = 11
11 = 11 (True).

members of a soccer team raised $741.15 to go to a tournament. They rented a bus for $250 and budgeted $25.85 per player for meals. they will spend all the money raised. write and solve an equation to determine the number of players the team could bring to the tournament
Answers
9514 1404 393
Answer:
19 players
Step-by-step explanation:
The total being spent is ...
bus cost + (per player cost) × (number of players) = total raised
250 + 25.85p = 741.15
25.85p = 491.15
p = 491.15/25.85 = 19
The team could bring 19 players to the tournament.

Bertha deposited $1000 into a retirement account when she was 18. How much will Bertha have in this account after 50 years at a yearly simple interest rate of 7.5%?
Answers
Answer:
$4750
Step-by-step explanation:
Simple interest is the interest calculated on the principal at a given rate for a time period.
The simple interest formula is given as,
SI = P x R x T / 100
P = principal
R = rate
T = time
Amount = SI + P
The amount Bertha will have in his account after 50 years is $4750.
What is simple interest?Simple interest is the interest calculated on the principal at a given rate for a time period.
The simple interest formula is given as,
SI = P x R x T / 100
P = principal
R = rate
T = time
We have,
P = $1000
T = 50
R = 7.5%
A = SI + P
SI = (1000 x 7.5 x 50) / 100
SI = 1000 X 7.5 X 50 / 1000
SI = $3750
A = SI + P
A = 3750 + 1000
A = $4750
Thus,
The amount Bertha will have in his account after 50 years is $4750.

Chuck and Holly are saving money to buy a car. Chuck has $500 already and is going to save $100 a month. Holly has $1000 and plans on saving $50 a month. In the space to the left, write an equation that shows when Chuck and Holly will have the same amount of money. What is the equation
Answers
Answer:
10 months
Step-by-step explanation:
Step one
Given
Chuck has $500
Chuckle wants to save $100 monthly
Let the number of months be x
And the total be y
So
Y=500+100x--------1
Holy has $500
Chuckle wants to save $500 monthly
Let the number of months be x
And the total be y
So
Y=1000+50x--------2
Equate 1 and 2
500+100x=1000+50x
1000-500=100x-50x
500=50x
x=500/50

Which unit rate is equivalent to 17 miles per gallon? (5 points)
Question 1 options:
1) 3 gallons
_________
51 miles
2) 51 miles
______
3 gallons
3) 34 miles
_____
4 gallons
4) 4 gallons
______
34 miles
Answers
Answer:
The answer would be option 2) 51 miles/3 gallons.
Step-by-step explanation:
First, every 17 miles needs 1 gallon. If you add 17 more miles, it'll be 34 miles and you'll need a 2nd gallon, so you can already eliminate options 3 and 4. If you add another 17 miles and a gallon, it'll give you 51 miles 3 gallons. Option 1 would not be the answer because if you did 3/51, you'll get a whole different answer in decimals. So the only other option to choose from is option 2.

Answers
Answer:
$246.75
Step-by-step explanation:
11.75 x 21 = 246.75
hope this helps <3
Answer:
If the student worked 21 hours this month, she will earn $246.75.
Step-by-step explanation:
Let [tex]x[/tex] equal hours.
If the student earns $11.75 per hour, we can represent this with the expression:
[tex]11.75x[/tex]
If she worked 21 hours this month, then:
[tex]x=21[/tex]
With that information, we can substitute [tex]21[/tex] for [tex]x[/tex] in the initial expression:
[tex]11.75(21)[/tex]
Multiply:
[tex]246.75[/tex]
Therefore, if the student worked 21 hours this month, she will earn $246.75.
-
We can check our work by setting the initial expression equal to our solution:
[tex]11.75x=246.75[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]11.75[/tex]:
[tex]x=21[/tex]
Since this quotient matches the number of hours she worked, our solution is correct!

In a paint factory, an old conveyer line has filled 40 barrels of paint, and is filling more at a rate of 1 barrel per minute. A worker just switched on a newer line that can fill 3 barrels per minute. In a little while, the two lines will have filled an equal number of barrels. How many barrels will each line have filled?
Write a system of equations, graph them, and type the solution.
Answers
Answer:
5 minutes
Step-by-step explanation:
let the time after which two lines will have filled an equal number of barrels is 'X' minutes.
so, according to the question after 'X' minutes;
⇒ number of barrels in old conveyer line = number of barrels in new conveyer line
⇒ 40x + 2X = 10X
⇒ X = 5

Answer:

Step-by-step explanation:
24/.29

but you want it rounded so 82.8 is your answer
I hope this helps
Answer:
82.8
Step-by-step explanation:
Step 1: If 29% of a number is 24, then what is 100% of that number? Set up the equation.
24 over 29% = Y over 100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
29Y = 24 x 100
29Y = 2400
Y = 2400 over 100 = 82.76
If you round 82.76 to the nearest tenth you get 82.8.
