[tex] -\dfrac{190}{63}x [/tex]
Step-by-step explanation:
You are adding two like terms which are fractions with denominators 9 and 7.
You need a common denominator. The LCD of 9 and 7 is 63.
[tex] -\dfrac{31}{9}x + \dfrac{3}{7}x = -\dfrac{31}{9} \times \dfrac{7}{7}x + \dfrac{3}{7} \times \dfrac{9}{9}x = -\dfrac{217}{63}x + \dfrac{27}{63}x = -\dfrac{190}{63}x [/tex]

a bottle contains 24.5 oz of water. a leak in the bottle causes it to lose 0.3 oz of water every minute. how many minutes does it take for the bottle to lose 33% of the water?
Answers
Answer 54.7 Minutes
Step-by-step explanation:
33% × 24.5 =
(33 ÷ 100) × 24.5 =
(33 × 24.5) ÷ 100 =
808.5 ÷ 100 =
8.085 ≈
8.09;
so then 8.09 - 24.5 = 16.41
16.41 divided by 0.3 = 54.7
54.7 minutes it take for the bottle to lose 33% of the water.
What is Percentage?The percentage formula is used to calculate the amount or percentage of anything in terms of 100. Percentage indicates "per hundred" in its most basic form. The percentage formula is used to express a number between zero and one. It is a number that is expressed as a fraction of 100. It is represented by the sign% and is mostly used to compare and find ratios.
We have a bottle contains 24.5 oz of water.
A leak in the bottle causes it to lose 0.3 oz of water every minute.
So, 33% × 24.5
= (33 ÷ 100) × 24.5
= (33 × 24.5) ÷ 100
= 808.5 ÷ 100
= 8.085
= 8.09
So, the amount water loses
= 24.5 - 8.09
= 16.41 oz
Now, the amount of time for bottle to loose 33% of water
= 16.41 / 0.3
= 54.7 minutes

The amount of water an electric dishwasher uses to wash dishes varies directly with the number of loads of dishes. The dishwasher uses 32 gallons of water to wash 4 loads of dishes.
How many gallons of water will the dishwasher use to wash 10 loads of dishes?
Answers
Answer:
It would be 80 gallons of water that the dishwasher will use to wash 10 loads of dishes. To figure this out you would need to divide 32 by 4 which would equal 8. You would do this to figure out how many gallons of water a dishwasher needs to wash 1 load of dishes. Then you would multiply 8 times 10 which would equal 80. Hope this helps you!
Step-by-step explanation:
Answer:
10 loads = 80 gallons of water
Step-by-step explanation:
First, we will be multiplying 4 by 2 so we can get 8loads=64 gallons now we have to find the 2 so divide 32 by 2 which is 16 then finally add them together which will bring 80

Answer:
y = 1 + -1Y
Step-by-step explanation:
Simplifying
13y + 2 + -2y = 10y + 3 + -1Y
Reorder the terms:
2 + 13y + -2y = 10y + 3 + -1Y
Combine like terms: 13y + -2y = 11y
2 + 11y = 10y + 3 + -1Y
Reorder the terms:
2 + 11y = 3 + -1Y + 10y
Solving
2 + 11y = 3 + -1Y + 10y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-10y' to each side of the equation.
2 + 11y + -10y = 3 + -1Y + 10y + -10y
Combine like terms: 11y + -10y = 1y
2 + 1y = 3 + -1Y + 10y + -10y
Combine like terms: 10y + -10y = 0
2 + 1y = 3 + -1Y + 0
2 + 1y = 3 + -1Y
Add '-2' to each side of the equation.
2 + -2 + 1y = 3 + -2 + -1Y
Combine like terms: 2 + -2 = 0
0 + 1y = 3 + -2 + -1Y
1y = 3 + -2 + -1Y
Combine like terms: 3 + -2 = 1
1y = 1 + -1Y
Divide each side by '1'.
y = 1 + -1Y
Simplifying
y = 1 + -1Y

CFMS has contacted a band to play at an upcoming event. The band will charge a travel fee of $525 plus $12.50 per ticket sold.The school decides to turn the event into a fundraiser by increasing the cost of the tickets. If they want to make a profit of $875, how much will they need to charge per ticket?
Answers
Answer:
x=28 so they need to charge 28 tickets
Step-by-step explanation:
525 + 12.50x=875
First, take the 525 and drag it to the other side which will become into negative so the equation will be 12.50x=875-525 now just subtract it and u will get the answer of 12.50x=350 now all you need to do is divide [tex]\frac{350}{12.5}[/tex] and now the answer will be x=28 to double check we can just multiply 12.5 times 28 = 350 now plus 525 is = to 875 hope this helped :>
