Answer:
0.05x+0.04y=117
y=2x
where:
x is the amount of all phone sales
y is the amount of all computer sales
Step-by-step explanation:
From the information given, the first equation would indicate that the comission of all phone sales plus the comission from all computer sales would be equal to 117, which is:
0.05x+0.04y=117, where:
x is the amount of all phone sales
y is the amount of all computer sales
Also, the statement indicates that Ethan had twice as much in computer sales as he had in phone sales, which would be:
y=2x
Now, you can replace y=2x in the first equation and solve for x:
0.05x+0.04(2x)=117
0.05x+0.08x=117
0.13x=117
x=117/0.13
x=900
Finally, you can replace the value of x in y=2x to find the value of y:
y=2(900)
y=1800

-8x +(-56)=16
Answer:
x = -9
-8x + -56 = 16
-8x - 56 = 16
-8x = 16 + 56
-8x = 72
x = 72/8
x= -9
Answer:
-9
Step-by-step explanation:
-8x + (-56) = 16
Take away -56 from both sides
-8x = 72
Divide both sides by -8
x = -9

To eliminate the y terms and solve for x in the fewest steps, by which constants should the equations be multiplied by before adding the equations together?
First equation: 4x − 3y = 34
Second equation: 3x + 2y = 17
1.The first equation should be multiplied by 2 and the second equation by 3.
2.The first equation should be multiplied by 2 and the second equation by −3.
3.The first equation should be multiplied by 3 and the second equation by 4.
4.The first equation should be multiplied by 3 and the second equation by −4.
Answer:
Multiply the first equation by 2 and the second equation by 3 to eliminate y
Step-by-step explanation:
First equation: 4x − 3y = 34
Second equation: 3x + 2y = 17
Multiply the first equation by 2 and the second equation by 3 to eliminate y
2( 4x − 3y = 34 ) = 8x -6y = 68
3( 3x + 2y = 17) = 9x +6y = 51
Add the equations together
8x -6y = 68
9x +6y = 51

If two triangles are similar with a zoom factor of 3, and the smaller one has area 12 sq. units, what is the area of the bigger one? the answer is 108 sq units, im curious how it got there
Answer:
Please check explanations
Step-by-step explanation:
Mathematically, the area of a triangle
A = 1/2 * b * h
b is base, h is height
For 12 square units, we can have a base of 6 and a height of 4
By tripling the dimensions for the second triangle, we will have a triangle of 18 by 12
So the new area is;
A = 1/2 * 12 * 18
That was how we got 108 square units

Answer:
For the chart, the missing number on top is 10. the bottom numbers are 1.5 then 9.
For the question, all of the numbers equal the ration 5:3.
Question 2: Yes. 30/x=2/4 which equals 60 (minutes) which is an hour.
Step-by-step explanation:
1A:
2.5 amount of water - 1.5 amount of pasta
10 amount water - 6 amount pasta
15 amount water - 9 amount pasta
2.5 : 1.5
5 : 3
10 : 6
15 : 9
1B. these quantities are proportional because they can all be simplified to the same unit rate of 5 : 3.
2. Johnny is correct. The rate is 4 : 2, with a unit rate of 2 : 1. If you multiply both sides by 30 (how many inches deep the hot tub is) you get a ratio of 60 : 30, meaning it would take an hour to fill up the tub.
What is the equation in slope intercept form of the line that passes through the point (2,2) and is perpendicular to the line represented by y=2/5x + 2
Answer:
y=
Step-by-step explanation:
Perpendicular means opposite reciprocal of the slope. This means that the slope would change from 2/5 to 5/2 and add a negative, so it is -5/2.
y=-5/2x+b
2=-5/2 (2) +b
7=b
y=-5/2x+7

The remainder should be 2, not 6. Francine mistakenly added 6 instead of 2, leading to the incorrect conclusion. The correct statement is that 86 divided by 4 is 21 with a remainder of 2.
Francine made a mistake in her reasoning. The correct statement would be that 86 divided by 4 is 21 with a remainder of 2, not 20 with a remainder of 6.
Let's analyze her reasoning using the equation she provided:
4x20 + 6 = 86
If we multiply 4 by 20, we get 80, not 86. So, the correct equation should be:
4x20 + 2 = 86
By solving this equation, we find that:
80 + 2 = 86
Hence, the remainder should be 2, not 6. Francine mistakenly added 6 instead of 2, leading to the incorrect conclusion. The correct statement is that 86 divided by 4 is 21 with a remainder of 2.

2x - 2y = 6 3x + 2y = 9 Solve the system of equations. A) x = 0, y = 3 B) x = 3, y = 0 C) x = 1, y = -2 D) x = -2, y = 1 E) x = 6, y = 3
There are 2 ways to solve this system: by elimination or by graphing. I will solve it by elimination. First will solve for x.
[tex]2x - 2y = 6\\3x + 2y = 9\\\\5x = 15\\\\x = 3\\[/tex]
Now we will solve for y using what we got for x.

Answer:
(x, y, z) = (2, 1, -5)
Step-by-step explanation:
There are numerous equation solvers available on the web. The attached result is from one of them.

You may find it easier to solve these by hand if you eliminate fractions.
2x -y +z = -2x +3y -z = 10x +0y +2z = -8The first step is to look to see what you have, then formulate a strategy for getting a solution. Because the equations containing y have opposite coefficients, one of which is -1, we choose to use those to eliminate y. Immediately, we will have two equations in x and z.
If you multiply the first equation by 3 and add that to the second, then you will eliminate y. The third equation already has y eliminated, so you will then have two equations in x and z.
3(2x -y +z) +(x +3y -z) = 3(-2) +(10)
6x -3y +3z +x +3y -z = -6 +10
7x +2z = 4 . . . . [eq4]
Subtracting the third equation from this eliminates z, so you have ...
(7x +2z) -(x +2z) = (4) -(-8)
6x = 12
x = 2
Substituting into the third equation gives ...
2 +2z = -8
2z = -10
z = -5
Then using the first equation, you have ...
y = 2x +z +2 = 2(2) +(-5) +2 = 1
(x, y, z) = (2, 1, -5)
Paula is the student council member responsible for planning an outdoor student dinner dance. Plans include
hiring a band and buying and serving dinner. She wants to keep the ticket price as low as possible to encourage
student attendance while still covering the cost of the band and the food.
1.) Band A charges $700 to play for the evening and Band B charges $550 plus $1.50 per student.
a. Write a system of equations to represent the costs of the two bands. Use y for total cost and use x for
number of students.
Answer:
Band A:y=700
Band B:y=550+1.50x
Step-by-step explanation:
Band A: since they are a fixed rate no matter how many students the equation would be y=700 . There is no need for x since there is no extra price for students
Band B: Since this band charges 550 plus 1.50 per student we will need a x in our equation
y=550+1.50x
The difference between the two equations is that in Band B we need to add the price per student.
a savings account earns 8% interest each year, compounded quarterly (4 times a year). If a person invests $100 and makes no further deposits or withdrawals, what is the balance in the account after 3 years?
===========================================
Work Shown:
The given values are
P = 100 = amount deposited (principal)r = 0.08 = decimal form of the annual interest raten = 4 = compounding frequencyt = 3 = number of yearsWhich means,
A = P*(1+r/n)^(n*t) .... compound interest formula
A = 100*(1+0.08/4)^(4*3) .... plug in given values
A = 126.824179456254 ..... value is approximate
A = 126.82 ...... round to the nearest cent
The balance of the account after three years is $126.82
Answer:
