- 7x-2y=-13
x - 2y = 1
Solve by substitution
multiply and subtract and do the x y across
Answer:
y = 3/8, x = 7/4
Step-by-step explanation:
x = 2y+1
-7(2y+1) - 2y = -13
-14y - 7 - 2y = -13
-16y - 7 = -13
-16y = -6
y = 3/8
Plug the value for y into one of the equations to solve for x

if there's 130 calories in 3/4 cup how many calories are in 1/4 cup
Answer:
your answer would be 130/3
Step-by-step explanation:
By a simple rule of 3, we will see that in 1/4 cup there are 43.33 calories.
Using the rule of 3.
We know that in 3/4 cup there are 130 calories, then we can write:
3/4 cup = 130 calories.
We want to know how many there are in 1/4 cup, let's say that there are X, then we can write:
1/4 cup = X
If we take the quotient of the two equations we get:
(3/4 cup)/(1/4 cup) = (130 calories)/X
Solving this for X we get:
3 = (130 calories)/X
X = (130 calories)/3 = 43.33 calories
So we can conclude that in 1/4 cup there are 43.33 calories.

In May, Yoder's Bookstore had sales of $5,000, cost of goods sold of $3,000,
operating expenses of $800, and taxes of $400. Calculate Yoder's gross profit and final
net income or loss.
Please answer this for me! Thank you ;)
Answer:
This reminds of gta but the answer is that Yoder's profit is 800 dollars
Step-by-step explanation:
5,000 - 3,000 - 800 - 400 = 600
Answer: The net or gross profit made by Yoder's Bookstore is $800 .
Step-by-step explanation:
The income statement records the entire revenues and total costs.
The business makes money if its overall revenues exceed its whole expenses.
Additionally, the business will experience a net loss if its overall sales fall short of its total expenses.
The retained earning account statement would show this net income or net loss.
In order to calculate the gross income, the sales amount must first be subtracted from the cost of the goods sold.
Total sales done by Yoder's Bookstore = $5,000
Total cost of sold goods = $3,000
Operating expenses beared by Yoder's Bookstore = $800
Taxes paid by Yoder's Bookstore = $400.
Gross profit earned by Yoder's Bookstore =
$5,000 - ($3,000+$800+$400)
Net profit earned by Yoder's Bookstore = $5000 -$4200 = $800
Hence, the net or gross profit made by Yoder's Bookstore is $800 .

If the perimeter of a square is 120f+80 inches, what is the length, in inches, of each side of the square?
Answer:
30f + 20
Step-by-step explanation:
A square has four sides, all of equal length. If we call that side length x, then the perimeter - the total length around the square - is 4x. To find the side length given the perimeter then, we can simply divide the perimeter by 4.
Our perimeter here is 120f + 80, and dividing each term by 4 gives us a side length of 30f + 20.
Which calculation and answer show how to convert 3/12 to a decimal
Plz help ASAP
Answer:
Its C
Step-by-step explanation:
It is C becuase when converting a fraction to a decimal, you just divide the numerator by the denominator
Basically solve the fraction
3/12=1/4
1/4 is a bencmark so right away you should know that should equal to 0.25 since its a quarter.
Or you can always look it like this
3 is the numerator
the “/“ between is basically ”divided by”
And the 12 is the denominator
Now read the equation in that order
3/12= 3 DIVIDED BY 12
There you go!

A. m = 4w - 2
B. m = 4w - 8
C. m = 2w - 4
D. m = 8w-4
Answer:
2m +4 =8w
2m = 8w -4
m=8w-4 / 2
m= 4w - 2

What is the area of triangle AOB? *picture attached* show work also please
Answer:
The area of the traingle AOB is 30 (Rounded up result)
Step-by-step explanation:
7.8 cm and 10 cm.
10/2= 5 cm
Then Reversed Pitagora's Formula:
Square root of the calc "(7.8^2)-(5^2)" = 60,84 - 25 = 35,84
Then Square root of 35, 84 is 5,98.
5.98 is the height of the triangle AOB
With the height we can calculate the area
We use the formula (B*H)/2
So is (10*5,98)/2, that makes 29,9
Just round up to 30 and that's the area.

You are planning the running shoe merchandise levels for your shoe store. Last year, your running shoe sales were down 10% from the previous season. The store had projected sales of 900 pairs of running shoes. Calculate the number of units the 10% sales decline represents.
Answer:
90
Step-by-step explanation: by taking 10% off of 900, you get 810; meaning 90 was subtracted
The number of units the 10% sales decline represents is 90
what is percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"
Given here projected sales = 900 but the actual sales is 10% less than this amount , thus actual sales = 900 - 10% of 900
= 900 -( 10/100 )×900
= 900 - 90
= 810
Hence, the number of units the 10% sales decline represents is 900-810 =90

The solution to the quadratic equation is x = -6 ± 2√7
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
x² + 12x + 25 = 17
Subtracting 17 on both sides , we get
x² + 12x + 8 = 0
And , roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
On simplifying , we get
x = ( -12/2 ) ± √ ( 12 )² - 4 ( 1 ) ( 8 ) / 2
x = -6 ± √ ( 144 - 32 ) / 2
x = -6 ± √112/2
And , the value of x = -6 ± 2√28/2
x = -6 ± 2√7
Hence , the solutions are x = -6 + 2√7 and -6 - 2√7
