This expression will simplify back to x-3y+7
Answer:
y= 1/3x-7/3
Step-by-step explanation:
We have: x-3y+7
There are many equivalent expressions we can create, but let's write this equation in slope- intercept form.
First step is to rearrange the terms: -3y=-x+7
But we are not done yet; now we divide both sides with -3: y=1/3x-7/3
(The negatives cancel out, which is why we get a positive 1/3)

There are five boys to every nine girls in an introductory engineering course .if there are 364 students enrolled in the course , how many are boys ?
Answer:
234
Step-by-step explanation:
So what we know is that
5x+9x= students
This equation is saying that for every 5 boys there are 9 girls
we can then plug in 364 for the number of students and add like terms
This means that 14x=364
this means that x=26
This means that there are 26 sets of 5 boys and 9 girls
this means that there are
130 boys

The measures of two sides of a triangle are 4in and 13in. Find all possible values that the third side of this triangle can be?
Answer:
9 < x < 17 is the possible length of the third side of a triangle.
Step-by-step explanation:
The Triangle Inequality theorem defines that if we are given two sides of a triangle, the sum of any two given sides of a triangle must be greater than the measure of the 3rd side.
Given the two sides of the triangle
4 in13 inLet 'x' be the length of 3rd size.
According to the Triangle Inequality theorem,
The difference of two sides < x < The sum of two sides
13 - 4 < x < 13+4
9 < x < 17
Therefore, 9 < x < 17 is the possible length of the third side of a triangle.

Mrs. Lenny is putting up a fence around her garden to keep the bunnies
out. The length of the garden is 8 feet more than the width. If the perimeter
of the garden is 308 feet, what is the length and the width?
Answer:
Length= 81 feet
width = 73 feet
Step-by-step explanation:
P=2{(8+W)+W}
308=2(8+2W)
308=16+4W
308-16=4W
292=4W
W=73
And length = 8+W
8+73=81
What percent of 25 is 50
Answer:
50 is 200% of 25
Step-by-step explanation:
50 is 200 percent of 25.
To find the percentage of one number in relation to another, we can use the following formula:
(Percentage / 100) * Base = Amount
In this case, we want to find what percentage of 25 is 50.
Let's use x to represent the percentage:
(x / 100) * 25 = 50
To solve for x, we can divide both sides of the equation by 25:
(x / 100) = 50 / 25
Simplifying:
(x / 100) = 2
Next, we can cross-multiply:
x = 100 * 2
Simplifying:
x = 200
Therefore, 50 is 200% of 25.

They both agreed they should first subtract 2x and add 8 to both sides and rewrite the equation as
22 + 6x + 8 = 0.
Then Esma said, "I can complete the square. I can add 1 to both sides to rewrite this equation as
22 + 6x + 9 = 1, factor, and solve using square roots."
Hunter said, "I'll factor the left-hand side of the equation as (x + 2)(x + 4) and solve using the zero

What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as its degree is two.
Given a quadratic equation x² + 8x = 2x - 8.
They both agreed that first subtract 2x and add 8 to both sides and rewrite the equation as
x² + 6x + 8 = 0.
Both of their strategies would work.
As x² + 6x + 9 = 1
(x + 3)² = 1.
x + 3 = ± 1
x = ± 1 - 3.
x = - 2 or - 4.
x² + 6x + 8 = 0.
x² + 4x + 2x + 8 = 0.
x(x + 4) + 2(x + 4) = 0.
(x + 4)(x + 2) = 0.
x = - 4 or x = - 2.

The Oliver Company plans to market a new dish washing detergent. The selling price will be $4
per container. Variable costs are estimated to be 46% of the selling price. Fixed costs are
estimated to be $6,115. What is the break-even point? That is, how many containers of the
detergent the company must sell in order to end up with no loss and no profit in its operations?
(Round your final answer to the nearest whole number).
Answer: 2,831 containers
Step-by-step explanation:
To find the breakeven point, use the following formula:
= Fixed cost / Contribution margin
Fixed cost = $6,115
Contribution margin = Selling price - Variable cost
= 4 - (4 * 46%)
= $2.16
Breakeven point = 6,115/2.16
= 2,831 containers

2. If Mr. Escobar had an initial investment of $50,000 and
the annual interest rate was 4%, how long would it take
to double his initial investment?
A)16 year
B)17
C)18
None of the above
Answer:
None of the above
Step-by-step explanation:
The correct answer to the given question is None of the above
Assuming simple rate
The calculation is shown below
$50,000 * 4% = $2,000
this makes an interest of $2,000 per year.
$2,000 / $50,000 = 25 years
It will take 25 years to double Mr. Escobars initial investment so the answer is none of the above.
Fifteen hungry kittens found a bucket of sausages. Each time they cut a sausage or a part of a sausage, they cut it into exactly two new pieces. They made 20 cuts in all and each kitten got 2 (maybe unequal) pieces of sausage. How many sausages were in the bucket?
Answer:
There is a total of 10 sausages. I am 100% sure.
Step-by-step explanation:
A bucket of sausages fed 15 hungry kittens. Each sausage or half of a sausage is sliced into two pieces. They chopped 20 sausages and gave each kitten two (perhaps unequal) portions. Therefore, there were 34,952 sausages in the bucket.
At the start, there is one sausage bucket, and the 15 kittens want to share it.
The first cut divides the sausage into two pieces.
After the second cut, there are four pieces of sausage.
After the third cut, there are eight pieces.
After the fourth cut, there are 16 pieces.
As we can observe, the number of pieces of sausage doubles with each cut. After 20 cuts, there will be 2²⁰ (2 raised to the power of 20) pieces of sausage.
Now, since each kitten received two pieces of sausage, the total number of sausages in the bucket can be calculated by dividing the total number of pieces by 2 × 15 (since there are 15 kittens).
Total sausages = (2²⁰) / (2 × 15)
Let's simplify this:
Total sausages = 2¹⁹ / 15
Now, let's calculate the value:
Total sausages = 524,288 / 15
Total sausages = 34,952.53
Since you can't have a fraction of a sausage, we need to round down to the nearest whole number.
Therefore, there were 34,952 sausages in the bucket.
