Step-by-step explanation:
Let the time used by Maggie be x
Since it It takes Elizabeth three times as long as Maggie to clean her room. Elizabeth will use: = 3 × x = 3x
Therefore, x + 3x = 6
4x = 6
x = 6/4 = 1.5 hours

3. Elise bought 5 boxes of cereal and 2 gallons of milk for a total cost of $31.24. Each box of cereal cost $4.80. Enter the cost, in dollars of 1 gallon of milk. Note: do not include the dollar sign, $, in your answer. *
Answer:
3.62
Step-by-step explanation:
Let
x = cost of cereal
y = cost of milk
5x + 2y = 31.24
x = $4.80
Substitute into the equation
5x + 2y = 31.24
5(4.80) + 2y = 31.24
24 + 2y = 31.24
2y = 31.24 - 24
2y = 7.24
y = 7.24 / 2
y = $3.62
Therefore,
1 gallon of milk cost $3.62

At the gym, Tika spends twice as much time doing aerobics than weight training. She stretches for one fifth of the time she spends on weight training. Let w be the amount of time Tika spends on weight training. Which expression represents her total workout?
Answer:
Her total workout is [tex]2w+w+\frac{w}{5}[/tex].
Step-by-step explanation:
Consider the provided information.
Let w be the amount of time Tika spends on weight training.
Tika spends twice as much time doing aerobics than weight training.
It means she spends [tex]2w[/tex] time doing aerobics.
She stretches for one-fifth of the time she spends on weight training.
It means she spends [tex]\frac{w}{5}[/tex] time for stretches.
The total workout time is:
[tex]2w+w+\frac{w}{5}[/tex]
Hence, her total workout is [tex]2w+w+\frac{w}{5}[/tex].

C The solution to the system is (-4,3)
OD The system has no solution
Answer:
The correct answer is Option C: The solution to the system is (-4,3)
Step-by-step explanation:
We can observe the graph to find the solution of the system.
There are three solutions to a system of equation
One solutionNo solutionInfinite many solutionsIn the given graph we can see that the two lines are only intersecting at one point so the system of equations has only one solution.
Observing the graph, we can see that the intersection point is (-4,3)
Hence,
The correct answer is Option C: The solution to the system is (-4,3)

Answer:
10Step-by-step explanation:
Period is the distance between two consecutive maximum points, or two consecutive minimum points.On the given graph the period is the distance between maximum points -7 and 3:
3 - (-7) = 10Answer:
The period of the sinusoidal function is 2π, i.e., the value of the function repeats at every 2π units.
From the origin towards right we can see that the distance traveled between 0 to 2π is 10 units
Therefore, 10 units is the right answer.
