Step-by-step explanation:
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.

The circumference of a circle is 31.4. What is the are of the circle?
A line goes through the points (6,2) and (−10,−3). Find its slope. Enter your answer as a simplified improper fraction, if necessary. Do not include "m=" in your answer. Provide your answer below:
-16/5
Step-by-step explanation:
calculating the gradient you use the formula change in y/change in X
subtract y coordinate -3-6=-5
subtract X coordinate -10-6 =-16
-16/5 = -16/5 or -3.2

0.9c - 2.3d
C= 17, D= 3
WHAT'S 0.9c - 2.3d
Answer:
8.4
Step-by-step explanation:
0.9c - 2.3d
given c = 17 and d = 3, substitute these into the expression:
0.9c - 2.3d
= 0.9(17) - 2.3(3)
= 15.3 - 6.9
= 8.4

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

Let A={2,3,4} B={2,5,6} C={5,6,2} and D={6}. Determine if the following statements are true:
i). 4€C
ii). 5€C
iii). A=B
iv). B=C
Answer:
i. 4∈C => False
ii. 5∈C => True
iii. A = B => False
iv. B=C => True
Step-by-step explanation:
Given sets are:
[tex]A = \{2,3,4\}\\B = \{2,5,6\}\\C = \{5,6,2\}\\D = \{6\}[/tex]
Lets look at the statements one by one.
i. 4∈C
This statement means that 4 is a member of set C. Looking at the members of set C, it can be concluded that the statement is wrong as C doesn't contain 4.
ii. 5∈C
This statement is true as 5 is a member of C.
iii. A=B
This statement states that set A is equal to set B. Two sets are said to be equal if there number of elements and members are same. Set A and Set B have different members so this statement is false.
iv. B=C
Set B and Set C have equal number of members and the members (5,6,2) are also same so the statement is true.
Hence,
i. 4∈C => False
ii. 5∈C => True
iii. A = B => False
iv. B=C => True
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.

Answer:453rft
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

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.
Hope this helped!
The Juniors and Seniors reported their scores on a standardized math test. The teacher displayed their scores on dot plots.
What is the MAD for the Junior and Senior scores?
0.7
29.3
14.3 and 15
14 and 14.4
Answer:
14 and 14.4
Step-by-step explanation:
✍️MAD for Juniors:
✔️Write out the individual scores represented in the dot plot:
505, 505, 510, 515, 525, 530, 530, 540, 550, 550
✔️Find the mean of the data set = [tex] \frac{505 + 505 + 510 + 515 + 525 + 530 + 530 + 540 + 550 + 550}{10} = \frac{5,260}{10} = 526 [/tex]
✔️Find |data value - mean|:
|505 - 526| = 21
|505 - 526| = 21
|510 - 526| = 16
|515 - 526| = 11
|525 - 526| = 1
|530 - 526| = 4
|530 - 526| = 4
|540 - 526| = 14
|550 - 526| = 24
|550 - 526| = 24
✔️Find the sum of |data value - mean| and divide by 10:
[tex] \frac{21 + 21 + 16 + 11 + 1 + 4 + 4 + 14 + 24 + 24}{10} = \frac{140}{10} = 14 [/tex]
✅M.A.D = 14
The same steps would be taken to find the MAD for Seniors.
✍️MAD for Seniors:
✔️Write out the individual scores represented in the dot plot:
535, 535, 535, 550, 550, 550, 560, 575, 575, 580
✔️Find the mean of the data set = sum of all values in the data set ÷ 10 = 554.5
✔️Find the M.A.D by dividing the sum of |data value - mean| by 10:
[tex] \frac{144}{10} = 14.4 [/tex]
✅M.A.D = 14.4
