A number is doubled and then increased by nine. The result is ninety- Three. What is the original number?
Answer:
42
Step-by-step explanation:
First you subtract 93 by 9. You get 84. Then you divide it by 2. Which is your answer, 42.
This can be represented as:
93=2x+9
First subtract 9 from both sides
84=2x
Then divide by 2 on both sides
42=x

2. Describe the process used to solve an equation with variables on both sides.
Answer:
After simplifying, the first step in solving an equation with a variable on both sides is to Get The Variable On One Side. This is done by reversing the addition or subtraction of one of the terms with the variable. In other words, we must add to both sides or subtract from both sides one of the quantities that contains the variable. It is generally easier to add or to subtract the smaller quantity from the larger quantity, so we are working with positive coefficients, but either way works

Write the equation of line in slope-intercept form.
Line parallel to y=−2x+3 that passes through the point (−100,−100)
Answer: y= -2x - 500
Step-by-step explanation:
Parallel lines have the same slopes but different y-intercepts. This means that the line parallel to y=-2x + 3 will have the same slope which is -2.
We will input the x and y coordinates for the given point into the formula and solve for the y-intercept to write the equation.
-100 = -2(-100) + b where b is the y-intercept
-100 = 400 + b
-400 -400
b = -500
The y intercept is -500 and the slope is -2 therefore, the equation will be
y= -2x - 500

Step-by-step explanation:
County day scholarship fund receives a gift of $130,000 the money is invested in stocks, bonds and CDs. CDs pay 2% interest, bonds pay 2.9% interest, and stocks pay 9.9% interest. country day invests $25000 more in bonds than in CDs. if the annual income from the investment is $8885, how much was invested in each vehicle?
country day invested $______ in stocks.
country day invested $______ in bonds.
country day invested $______ in CDs.
Answer:
$15,000 was invested in CDs.
$40,000 was invested in bonds.
$75,000 was invested in stocks.
Step-by-step explanation:
Let C be the amount invested for CDs, B be the amount invested for bonds, and S be the amount invested for stocks.
We know that the total amount invested must be $130,000 because that was the amount given to the Scholarship Fund. So:
[tex]C+B+S=130000[/tex]
We know that CDs pay 2% or 0.02 interest; Bonds pay 2.9% or 0.029 interest; and Stocks pay 9.9% or 0.099 interest. In total, the investment earned $8,885. So:
[tex]0.02C+0.029B+0.099S=8885[/tex]
Let's remove the decimals by multiplying everything by 1000. This yields:
[tex]20C+29B+99S=8885000[/tex]
Now, we know that $25000 more was invested in bonds than CDs. So:
[tex]B=25000+C[/tex]
We have a triple system of equations. We can solve this using substitution. Let's substitute our third equation into the second equation. This yields:
[tex]20C+29(25000+C)+99S=8885000[/tex]
We want to isolate the C variable. Here, we removed the B but we still have an S.
So, to remove the S, we can go back to our first equation. We have:
[tex]C+B+S=13000[/tex]
Subtract C and B from both sides:
[tex]S=130000-C-B[/tex]
We can now substitute this for S:
[tex]20C+29(25000+C)+99(130000-C-B)=8885000[/tex]
We got a B again. But, we already know what B is. Substitute:
[tex]20C+29(25000+C)+99(130000-C-((25000)+C))=8885000[/tex]
So, our equation is now in terms of C. Solve for C. Distribute on the far right:
[tex]20C+29(25000+C)+99(130000-C-25000-C)=8885000[/tex]
Combine like terms:
[tex]20C+29(25000+C)+99(105000-2C)=8885000[/tex]
Distributive Property:
[tex]20C+725000+29C+10395000-198C=8885000[/tex]
Combine like terms:
[tex](20C+29C-198C)+(725000+10395000)=8885000[/tex]
Add:
[tex]-149C+11120000=8885000[/tex]
Subtract 1112000 from both sides:
[tex]-149C=-2235000[/tex]
Divide both sides by -149:
[tex]C=15000[/tex]
So, a total of $15,000 was invested in CDs.
Since $25,000 more was invested in bonds than in CDs, this means that a total of $25000+$15000 or $40,000 was invested in bonds.
To find out how much was invested in stocks, we can use our first equation again:
[tex]C+B+S=130000[/tex]
Substitute 15000 for C and 40000 for B:
[tex]15000+40000+S=130000[/tex]
Add:
[tex]55000+S=130000[/tex]
Subtract 55000 from both sides:
[tex]S=\$75000[/tex]
So, $15,000 was invested in CDs, $40,000 was invested in bonds, and $75,000 was invested in stocks.
And we're done!
Answer:
$15,000 was invested in CDs.
$40,000 was invested in bonds.
$75,000 was invested in stocks.

Find the volume of the prism.
6 cm
5 cm
7 cm
5 cm
6 cm
Answer: Possibly, 105 cm³ if it is a triangular prism, or
Possibly 210 cm³ if it is a rectangular prism
Step-by-step explanation: Without knowing exactly what kind of prism it is, it is impossible to give an exact answer.
If the bases are triangles with altitude and and base of 5 and 6, anf the height of the prism is 7, the volume is
(6×5)/2 × 7
30/2 ×7
15 × 7 = 105 cm³ for a triangular prism
If the bases are rectangles with length and and width of 6 and 5, and the height of the prism is 7, the volume is
6×5×7 = 210 cm³ for a rectangular prism

<1 and <2 form a linear pair. The measure of <2 is six more than twice the measure of <1. Find the measure of <2
Answer:
122 Degrees
Step-by-step explanation:
Since we are given that angle 1 and 2 make a linear pair:
angle 1 + angle 2 = 180 degrees ----------------------------(1)
We have also been told that angle 2 is 6 more than twice the measure of angle 1
Which means: angle 2 = (2*angle1) + 6 -------------------(2)
From putting the value of angle 2 in (1) from (2)
angle 1 + 2*angle 1 + 6 = 180
3*angle 1 = 174
angle 1 = 58 degrees -----------------------(3)
From (1) and (3):
angle 2 + 58 = 180
angle 2 = 122 degrees
Therefore, the measure of angle 2 is 122 degrees
Here are four logos.
Which two logos have more than one line of symmetry?
Answer:
A and C
Step-by-step explanation:
A and C
Thank you
The logos have more than one line of symmetry are Option(c) and Option (1)
What is a line of symmetry?
A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly. Equally, if you were to place a mirror along the line, the shape would remain unchanged. A square has 4 lines of symmetry, as shown below.
According to the question
Logos have more than one line of symmetry
are option A and Option C
As in Option A if we cuts the shape exactly in half along lines marked in circle
There half will be same
so , there are 3 lines of symmetry in option A.
Now, In option 4
if we cuts the shape exactly in half along the middle of horizonal and vertical side of square figure
There half will be same
So , there are 2 lines of symmetry in option C.
Hence, The logos have more than one line of symmetry are Option(c) and Option (1) .

Bao can eat 12 chicken wings in 3 minutes. She eats the chicken wings at a constant rate.
How many chicken wings can Bao eat in 12 minutes?
chicken wings
Stuck?
Answer:
48
Step-by-step explanation:
If Bao eats 12 chicken wings in 3 minutes than that will help us find the unit rate by dividing 12 by 3, and then you will get 4. Now that you know the unit rate you will multiply it by 12 and get 48.
Answer:
For this we have to do simple division and multiplication, giving us the answer of 48.
Step-by-step explanation:
The easiest way to solve this is to first divide 12 by 3, giving us 4, the amount of time it would take for Bao to eat a single chicken nugget. And then since the question asks how many Bao can eat in 12 minutes, you would multiply 4 by 12, thus giving you the answer of 48.

The first-place seller will receive $20 more than second-place seller. How much will each of the top three sellers receive if the profit portion they will share is $200?
Answer:
1st - $92
2nd - $72
3ed - $36
Step-by-step explanation:
save 20 dollars for first place, because they are going to get that no matter what.
200 - 20 = 180
we'll need to divide 180 into 5 parts, one for 3ed place, two each for 1st and second.
180 / 5 = 36
3ed place gets $36
2nd gets twice that, $72
1st gets the same as 2nd +$20, so $92
to check our answer, add up all their profit and make sure it's 200 even.
