A water tank holds 880 gallons but is leaking at a rate of 5 gallons per week. A second water tank holds 1,100 gallons but is leaking at a rate of 9 gallons per week. After how many weeks will the amount of water in the two tanks be the same?
Answer:
62 weeks
Step-by-step explanation:
What we need is to represent the ratios in expression
For example if we have 992 gallons and the leaking is 5 gallons per week, the expression for the gallons after every week is
992-5x
x is the weeks
And the other case the expressions is
1240-9x
The question is the weeks for the amount being the same, then every equation can be equal to Y and it represent the same amount
992-5x=y
1240-9x=y
in both the y is the same, then
992-5x=1240-9x
992-1240=-9x+5x
-248=-4x
-248/-4=x
62=X
and that is the weeks we need for the amount being the same in both tanks
Answer:
62 weeks correct me if i'm wrong

Solve this problem in your math notebook, and upload it to the assignment.
Answer: Less, 44 cents
Step-by-step explanation: The new price is 5/4 of a dollar and in decimal form would be 1.25. The old price is 1.69 dollars meaning the new price is a better deal. To find the difference we subtract 1.25 from 1.69 giving us $0.44

A bus travels two different routes: the Green Route and the Blue Route. The routes are
different lengths.
• On Monday the bus traveled the Green Route 6 times and the Blue Route 5 times,
traveling a total of 52 miles.
• On Tuesday the bus traveled the Green Route 12 times and the Blue Route 13 times,
traveling a total of 119 miles.
What is the length of the Green Route in miles?
Set up a system of equations and say green route is x and blue route is y
This will give you
Monday 6x + 5y= 52
Tuesday 12x + 13y = 119
Solve by multiplying the top equation by two to get
12x + 10y= 104
Since you have 12x in both equations, these cancel out when you subtract the bottom from the top. This leaves you with
-3y=-15
Y=5
The blue route is 5 miles, but they want to know the green route. Fill in the y value in either one of your equations. Let’s use the one from Tuesday
12x + 13 (5) = 119
12x= 54
X= 4.5
This means that the answer is 4.5 miles
The length of the Green Route in miles is 4.5 miles.
Formulate an equation for Monday and Tuesday
Monday
6x + 5y= 52............Equation 1
Tuesday
12x + 13y = 119............Equation 2
Multiply the equation
12x + 10y= 104
-3y=-15
Divide both side by 3y
y=15/3
y=5
Plug in 5 into equation 2
12x + 13 (5) = 119
12x+65=119
12x=119-65
12x= 54
Divide both side by 12x
x=54/12
x= 4.5 miles
Inconclusion the length of the Green Route in miles is 4.5 miles.

ASAP PLZZZZZZZZ HELP _____________ waves need a medium to travel, but _____________ waves do not.
Group of answer choices
sound; light
sound; electrical
light; sound
electrical; light
Answer:
Sound waves need a medium to travel, but light waves do not.
Step-by-step explanation:
Sound waves need a medium to travel because they cannot travel through a vacuum. This is because sound travels by producing vibration in the molecules of the medium surrounding it and there are virtually no molecules in a vacuum. Light doesn't need a medium through which to travel because the speed of light is experimentally constant.

5x+3y=18 and 3x-3y=15 solve for y and x using elimination method
Answer:
x = 4.125 or [tex]4\frac{1}{8}[/tex]
y = -0.875 or [tex]-\frac{7}{8}[/tex]
Step-by-step explanation:
5x + 3y = 18
3x - 3y = 15
3y and -3y can be cancled out becuase + and - cancel out and they both have 3y in them. We don't have to switch any signs in this case. You can just add them all exept 3y and -3y becuase they will be canceled out.
8x = 33
x = 4.125
Now we know what x is. We need to figure out what y is now. To figure out y chose an equation from the problem and plug in the x value. Lets chose 3x - 3y = 15.
3(4.125) - 3y = 15
12.375 - 3y = 15
-3y = 2.625
y = -0.875
Now we know what y is. I hope this helps :)

Jeff is 4 times older than his daughter. Five years ago he was 9 times older than his daughter. Write an algebraic equation to determine the age of his daughter.
Jeff is 32, His Daughter is 8
The relationship between the age of Jeff and his daughter can be summarized by the following systems of equation:
Jeff's age = x
Jeff's Daughter's age = y
x=4y jeffs age is equal to his daughters times four
x-5=9(y-5) jeffs age minus five is equal to his daughters age minus five as well times 9
Combining these equations will get us x=32, y=8.
The algebraic equation 4D - 5 = 9D - 45. The current age of Jeff's daughter is 8 years old.
Let's represent the current age of Jeff's daughter as "D" and Jeff's current age as "J".
According to the problem:
Jeff is 4 times older than his daughter, so we can express this relationship as:
J = 4D
Five years ago, he was 9 times older than his daughter. This means that their ages five years ago are:
(J - 5) = 9(D - 5)
Now, we can write the algebraic equation to determine the age of his daughter (D):
(J - 5) = 9(D - 5)
Since we already know that J = 4D, we can substitute this into the equation:
(4D - 5) = 9(D - 5)
Now, we can solve for D, which represents the current age of Jeff's daughter. Expanding equation:
4D - 5 = 9D - 45
Next, move the variables to one side and the constants to the other side of the equation:
4D - 9D = -45 + 5
Combine like terms:
-5D = -40
Finally, solve for D:
D = -40 / -5
D = 8
Therefore, the current age of Jeff's daughter is 8 years old.
