Michelle is a server in a restaurant. On a weekend night, Michelle earned $4 an hour and $65 in tips. She made a total of $93. Write and solve an equation to determine how many hours she worked. On Monday, Ken spent half of his money on a new game. The next day he earned $12 mowing lawns. He now has $32. How much money did Ken have before bought the game? I need the equation too.
Answer:
first question: Michelle worked for 7 hours
second question: Ken had $40 before buying the game
Step-by-step explanation:
4x + 65 = 93
4x = 28, x = 7
Michelle worked for 7 hours
Ken 1/2x + 12 = 32
1/2x = 20
x = 20. 20*2 = $40, ken has $40 before buying the game.

Answer:
[tex]\Large\boxed{\text{The amount of money changes by \$50 per week.}}[/tex]
[tex]\Large\boxed{s(t) = 70+50t}[/tex]
Step-by-step explanation:
We can create a function based on this scenario.
We know that you start with $70. This would be a constant. So, we already know that our function will contain +70.
If we earn $50 a week, we know that we can create an expression here to find how much we make based on how many weeks we spend, assuming t represents the amount of weeks we spent.
[tex]50t[/tex]
We can add this to our original constant of 70.
[tex]70+50t[/tex]
Since the output will be a function based on how many weeks we spend, we can make it equal to s(t).
[tex]s(t) = 70+50t[/tex]
The slope here is 50, meaning that every week we earn 50 dollars more.
This means the amount of money changes by 50$ per week.

Consider these functions: f(x) = 4x^3 - 10 g(x) = [tex]\frac{3x - 4}{2}[/tex] What is the value of g(f(2))?
A. -6
B. 2
C. 19
D. 31
Answer:
D. 31
Step-by-step explanation:
First Plug 2 into f(x) and solve.
You should get 22.
Then plug f(2) which is equal to 22 into g(x).
So, plug 22 into g(x).
You should get 31.

Step-by-step explanation:
Answer:
-1.6r + 1.8
Step-by-step explanation:
-1.6 (r+2) +5
^ the -1.6 can be distributed to the (r+2) because it's basically multiplying
that becomes --> -1.6r + -3.2 + 5
Now the -3.2 and 5 are like terms so they can be solved together
-> -3.2 + 5 = 1.8
Now, -1.6r and 1.8 are not like terms because 1.8 does not have an r attached to it so you cannot do nothing from there
your answer becomes = -1.6r + 1.8

Now the slopes and the y-intercepts.
Given an equation y=-3x +5, explain the steps for using slope-intercept form to graph this equation.
A.Use the y-intercept to plot the point (0,5). Then, using the y-intercept as a reference point move left 3 units and up 1 unit, and plot a second point.
B. Use the y-intercept to plot the point (5,0). Then, using the y-intercept as a reference point, move right 3 units and up 1 unit , and plot a second point.
C.Use the y-intercept to plot the point (5,0). Then, using the y-intercept as a reference point, move left 3 units and up 1 unit, and plot a second point.
D. Use the y-intercept to plot the point (0,5). Then using the y-intercept as a reference point, move left 1 unit and up 3 units, and plot a second point
Answer:
A.Use the y-intercept to plot the point (0,5). Then, using the y-intercept as a reference point move left 3 units and up 1 unit, and plot a second point.
Step-by-step explanation:
5 is the y intercept, so 0,5 is where you would start and then 3 is the same as 3/1 so you go up 3 over 1.

Find - 1 5/6 + (-1/3) in a number line
Answer:
put it on -1
Step-by-step explanation:
you turn the mixed number into an improper fraction and then you turn -11/6 to have a denominator of 3 so then it comes out to -1 1/2 over 3 then you multiply the 3 times 2 and the 1 1/2 times 2 and you get -3/3 and equals out to -1

Erin weighs 135 pounds and is gaining ½ pound each week. Miranda weighs 143 pounds and is losing ¼ pound each week. Write an equation that could be used to determine x, the number of weeks that it will take until the two girls weigh the same amount?
Answer:
10.66 weeksStep-by-step explanation:
Number of weeks is x
135 + 1/2x = 143 - 1/4x1/2x + 1/4x = 143 - 1353/4x = 8x = 32/3 = 10.66 weeksAnswer:
[tex]135+\frac{1}{2}x=143-\frac{1}{4}x[/tex]
Step-by-step explanation:
Let E represent Erin’s weight, and let M reprevent Miranda’s weight.
And let x represent the amount of week that passes.
Eric is currently 135 pounds. However, she is gaining 1/2 pounds per week x.
Hence, we can write the following equation:
[tex]D=135+\frac{1}{2}x[/tex]
Miranda currently weights 143 pounts. However, she is losing 1/4 pounds per week x.
Since she is losing weight, 1/4 is negative. Hence:
[tex]M=143-\frac{1}{4}x[/tex]
When the two girls weigh the same, D=M. Thus:
[tex]D=M[/tex]
Substitute them for their respective equations to acquire:
[tex]135+\frac{1}{2}x=143-\frac{1}{4}x[/tex]
Notes:
To solve, first eliminate the fractions by multiplying everything by 4. This yields:
[tex]540+2x=572-x[/tex]
Add x to both sides. Subtract 540 from both sides:
[tex]3x=32[/tex]
Divide both sides by 3:
[tex]x=32/3\approx10.67[/tex]
Hence, it will take about 11 weeks for the girls to weigh the same.
