Answer:
A=1, m=2, v=1
Step-by-step explanation:
A.
[tex]-15=-7a-4-4a\\\\-15+4=-11a-4+4\\\\-11=-11a\\\\a=1[/tex]
B.
[tex]m-4m=-6\\\\\\-3m=-6\\\\\\3m=6\\\\m=2[/tex]
C.
[tex]8v-3+3v=8\\\\11v-3=8\\\\11v-3+3=8+3\\\\11v=11\\\\v=1[/tex]
For A, I first subtracted -4 from -7 as their variables are the same. I cannot subtract integers from variables. Then, I added 4 on both sides to move the integer on the left side. (This would also remove the -4 on the right side because -4+4=0) Then I divided -11 by both sides to get 1a or a.
For B, I subtracted -4 from 1 as their variables are the same. This time, since they are both negative numbers, I can make them both positive. So, just divide 3 by both sides as we want to get 1m.
For C, Add 3 to 8 as v is their variable. Then, I added 3 to both sides because we want to get the variable on one side. Divide by 11 and you will get v=1.

What are the x intercept and y intercept of the graph of 5x+8y=20
Answer:
x intercept: (4,0)
y intercept: (0,2 1/2)
Step-by-step explanation:
x intercept is (4, 0) and y intercept is (0,5/2) of the graph of 5x+8y=20
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
5x+8y=20
8y=-5x+20
Divide both sides by 8
y=-5/8x+20/8
y=-5/8x+5/2
Now put x=0 to find y intercept
y=5/2
Now put y=0 to find x intercept
-5/2=-5/8x
4=x
Hence, x intercept is (4, 0) and y intercept is (0,5/2).

Mia buys 50 coats at $28 each she sells 38 of these coats at$49 each she sells the rest of the coats at$40 each find the overall percentage profit mia has made on these coats
Answer:
67.28 %
Step-by-step explanation:
Given that:
Price at which the coats are bought = $28
Number of coats bought = 50
Total money spent on buying the coats = 50 [tex]\times[/tex] 28 = $1400
Number of coats sold at $49 each = 38
Money earned by selling 38 coats at $49 each = $1862
Number of coats left = 50 - 38 = 12
Money earned by selling 12 coats at $40 each = $480
Total money earned = $1862 + $480 = $2342
To find:
The overall profit percentage made by Mia ?
Solution:
Formula for Profit percentage:
[tex]Profit\% = \dfrac{Sales\ Price - Cost\ Price}{Cost\ Price}\times 100\\\Rightarrow Profit\% = \dfrac{2342 - 1400}{1400}\times 100\\\Rightarrow Profit\%=\dfrac{942}{1400}\times 100\\\Rightarrow Profit\%=67.28\%[/tex]
Therefore, overall percentage profit made by Mia by selling the coats= 67.28 %

The balance on a checking account is -$15. Interpret the direction and magnitude of this value.
A.The owner of the checking account is owed -$15.
B.The owner of the checking account is owed $15.
C. The checking account is overdrawn by -$15.
D.The checking account is overdrawn by $15.
Answer:
D. The checking account is overdrawn by $15.
Step-by-step explanation:
Since the balance on a checking account represents the remaining money left in that checking account, having a negative value for that would mean an overdrawing of money, or drawing more money than is in that account in the first place.
Therefore, the answer would be that the checking account is overdrawn by $15.

Answer: Any positive number less than 16
The diagram shows AD = 16. Applying a dilation with positive scale factor less than 1, will make the figure shrink. Segment AD becomes smaller, so the new AD will be some length less than 16.
For instance, if you use a scale factor 1/2 = 0.5, then AD = 16 turns into A'D' = 16*0.5 = 8

The high for a winter day in Sitka,
AK was 10 degrees below zero. The
low for the same day was 25
degrees below zero. What was the
range of temperatures for the day?
Answer:
The maximum temperature will be -10°C, then if T represents the temperature, we can write this as:
T ≤ -10°C
And the minimum temperature will be -25°C, then we must have that:
T ≥ -25°C
if we use both conditions, we will have:
-25°C ≤ T ≤ -10°C
We can write this range:
[-25°C, -10°C]
Where the [] symbols mean that the extremes are possible temperatures.
The length of the range will be:
-10°C - 25°C = 15°C.

Ravi wants to buy a new guitar that costs $129.99. He has $27, and decides to give music lessons to earn the rest of the money. Ravi decides to charge $22 per lesson. Which inequality would best help Ravi find m, the number of lessons he would need to give in order to buy the guitar?
A. 22m + 27 129.99
The inequality that would help Ravi the best to find m, the number of lessons he would need to give in order to buy the guitar will be 27 + 22 m ≥ 129.99.
Cost of guitar that Ravi wants to buy = $ 129.99
The amount of money that he has = $27
The amount of money that he will get per lesson = $ 22
Let the number of lessons given by Ravi be m.
Now, we know that he has to earn $ 129.99 or more to purchase the guitar.
So, the inequality will become:
27 + 22 m ≥ 129.99
Therefore, we get that, the inequality that would help Ravi the best to find m, the number of lessons he would need to give in order to buy the guitar will be 27 + 22 m ≥ 129.99.
