Wilbur and Mike are selling fruit for a school fundraiser. Customers can buy small boxes of grapefruit and large boxes of grapefruit. Wilbur sold 3 small boxes of grapefruit
and 14 large boxes of grapefruit for a total of $306. Mike sold 7 small boxes of grapefruit and 7 large boxes of grapefruit for a total of $252. What is the cost each of one
small box of grapefruit and one large box of grapefru
Answer:
both size boxes are $18 each
Step-by-step explanation:
Let x and y represent the costs of the small and large boxes, respectively. Then the two sales are ...
3x +14y = 306
7x +7y = 252
Doubling the second equation and subtracting the first, we have ...
2(7x +7y) -(3x +14y) = 2(252) -(306)
11x = 198
x = 18
y = 252/7 -x = 36 -18 = 18
A small box costs $18, as does a large box.
Answer:
both size boxes are $18 each
Step-by-step explanation:
Let x and y represent the costs of the small and large boxes, respectively. Then the two sales are ...
3x +14y = 306
7x +7y = 252
Doubling the second equation and subtracting the first, we have ...
2(7x +7y) -(3x +14y) = 2(252) -(306)
11x = 198
x = 18
y = 252/7 -x = 36 -18 = 18
A small box costs $18, as does a large box.

To solve the figure. You need to split the shape up with the lines shown.
Let's solve the top triangle first.
The formula to find the area of a triangle is y = 1/2(b*h)
So the base is 2+2+6 which equals 10. And the height is 4.
So y = 1/2(4*10)
PEMDAS solve parentheses first.
y = 1/2(40)
y = [tex]20cm^{2}[/tex]
Now solve the bottom left one.
y = 1/2(2*2)
y = 1/2(4)
y = [tex]2cm^{2}[/tex]
Now the bottom right triangle.
y = 1/2(6*2)
y = 1/2(12)
y = [tex]6cm^{2}[/tex]
And to solve area of a square is
y = b*h
y = 2*2
y = [tex]4cm^{2}[/tex]
And add all of it up to get
y = [tex]20cm^{2}+2cm^{2} +6cm^{2} +4cm^{2} = 32cm^{2}[/tex]
Area = [tex]32cm^{2}[/tex]
solve for c a(c-b)=d
Answer:
[tex]c=\frac{d + ab}{a}[/tex]
Step-by-step explanation:
Step 1: Write equation
[tex]a(c-b)=d[/tex]
Step 2: Solve for c
Distribute a: [tex]ac-ab=d[/tex]Add ab to both sides: [tex]ac=d + ab[/tex]Divide both sides by a: [tex]c=\frac{d + ab}{a}[/tex]Answer:
c=d+ab/a
Step-by-step explanation:
a( c-b)= d
ac - ab= d
+ab +ab
ac= d-ab
/a /a
c= d+ab/a
Let U = {9, 10, 11, 12, 13, 14} and A = {11, 13}. Determine whether the statement A⊂U is true or false and find A'.
a. false; A' = {11, 12, 13, 14}
b. true; A' = {9, 10, 11, 12, 14}
c. false; A' = {9, 12, 14}
d. true; A' = {9, 10, 12, 14}
Answer:
D; A⊂U is true and A'={9, 10, 12, 14}
Step-by-step explanation:
A={11,13}
Because those numbers are included in the statement U={9,10,11,12,13,14}, we can say that it's true that A belongs to U.
A' is the numbers of U not including A. So, it would just be U without the 11 and 13, or {9,10,11,12}
Can I have the answers for both questions pls! : ) it's due in tomorrow morning
Answer:
B) y = 35°
Step-by-step explanation:
Any quadriteral is you can add a line that links opposite corners of the quadrilateral and split it into two triangles. Added a single line the links opposite vertices of the quadrilateral and that splits it into two triangles. The angle rule that angles in a triangle add up to 180 degrees so the angle must add up to 180 degrees because of that angle rule and then in the other triangle the angles in that one must add up to 180 degrees. But the quadrilateral is made up of both triangles so you need all the angle in both those triangles to make up the angles of the quadrilateral so two lots of 180 degrees make up for 360 degrees. (180° plus 180° = 360°)
B) 118° plus 67° pus y plus 4y = 360° ( add all the angles that are inside of the quadrlateral)
185° plus 5y = 360° ( 118 degrees plus 67 degrees is 185°, 5y from to y plus 4y. its like you have 1y plus 4y)
5y = 360° - 185° ( subtract 180 degrees from both sides)
5y = 175°
divide by both side by 5, the value of y is 35°
Find the Unit Rate on a 5-gallon bucket of paint that costs $68.75
Answer:
$13.75 per gallon
Step-by-step explanation:
To solve for any unit rate you use
[tex]\frac{1}{x} =\frac{5}{68.75}[/tex]
Cross multiply.
So 68.75 = 5x
Divide both sides by 5 to get x alone.
13.75 = x
Therefore 1 gallon equals $13.75

Suppose that gas costs Big Ray $2.00/gallon and that he pays an attendant $100/day. Let C(x)
represent the total daily cost as a function of the price of the gas. Find the formula for C(x)
Answer:
C(x) = 2x + 100
Step-by-step explanation:
Here, we want to find the formula for C(x)
Here, x will be the number of gallons of gas
so per day, if x gallons of gas were consumed, the daily cost here will be x * 2 = $2x
Adding the cost for the attendant, we have 2x + 100
So the formula for C(x) will be;
C(x) = 2x + 100

Christa has a rectangular rug in her living room that is 6 feet wide and 8 feet long. She decides that the rug is too small for the room, so she orders a new one that covers twice as much area. If the new rug is 1.5 times as wide as the original rug, how long, in feet, is the new rug?
Given:
A rectangular rug in her living room that is 6 feet wide and 8 feet long.
She orders a new one that covers twice as much area.
New rug is 1.5 times as wide as the original rug.
To find:
The length of new rug.
Solution:
We have,
Length of rug = 8 feet
Width of rug = 6 feet
Area of rug is
[tex]Area=length \times width[/tex]
[tex]A_1=8 \times 6[/tex]
[tex]A_1=48\text{ sq. feet}[/tex]
Area of new rug is twice of area of original rug.
[tex]A_2=2\times A_1[/tex]
[tex]A_2=2\times 48[/tex]
[tex]A_2=96\text{ sq. feet}[/tex]
New rug is 1.5 times as wide as the original rug.
Width of new rug = 1.5 × 6 = 9 feet
Let the length of new rug be x feets. So, area of new rug is
[tex]A_2=x\times 9[/tex]
[tex]96=x\times 9[/tex]
Divide both sides by 9.
[tex]\dfrac{96}{9}=x[/tex]
[tex]\dfrac{32}{3}=x[/tex]
[tex]x=\approx 10.67\text{ feet}[/tex]
Therefore, the length of new rug is about 10.67 feet.
They need to raise $1,680 for travel expenses. Each chocolate bar is being sold for $2, and each box contains 30 chocolate bars. There are seven scholars on the team and they agree to each sell the same number of boxes. How many boxes will each scholar have to sell in order to raise enough money to cover the team's travel expenses?
Answer:
Each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses
Step-by-step explanation:
Let x denotes number of boxes to be sold by each scholar to raise enough money to cover the team's travel expenses.
Number of scholars = 7
Total number of boxes [tex]=7x[/tex]
Total number of chocolate bars [tex]=(7x)(30)=210x[/tex]
Price of 1 chocolate bar = $2
Price of [tex]210x[/tex] chocolate bars [tex]=210x(2)=\$420x[/tex]
Also,
Total amount to be raised for travel expenses = $1680
So,
[tex]1680=420x\\x=\frac{1680}{420}\\ x=4[/tex]
Therefore,
each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses
Dave is making lemonade. For each 8 cups of water, he uses 3 cups of lemon juice and 2 cups of sugar. If w the number of cups of water, l is the number of cups of lemon juice, and s is the number of cups of sugar, which equations are correct?
A. l = 3/8 (w)
B. l = 3s
C. w= 4s
D. l = 2/3 (s)
Answer: A and C are correct.
Step-by-step explanation:
Look at the proportions. For 8 cups of water there are 3 cups of lemon juice. So L 3/8(w)
For 8 cups of water there are 2 cups of sugar. 8 is 4 times 2. So the amount of water is 4 times the amount of sugar. W= 4s
Solve the following equation.
X + 5 = 2x
Can some explain to me how to do this? I have to add one of these numbers to both sides of the equation but idk which one.
Answer:
x = 5
Step-by-step explanation:
Subtract x from both sides.
Your equation would look like this now:
5 = 1x
Divide both sides by 1.
x = 5
Hope you understand :)
Please consider Brainliest :)
[tex]x + 5 = 2x[/tex]
[tex]5 = 2x - x[/tex]
[tex]5 = 1x[/tex]
[tex]x = 5[/tex]
Let us check whether or not we have found out the correct value of x , by placing 5 in the place of x .
Which means :-
5 + 5 = 2 × 5
10 = 10
LHS = RHSHence proved that the value of x = 5 .
Therefore , 5 + 5 = 2 × 5 , ( x = 5 ) .
Rebecca writes 1/5 of a page in 1/14 minute. How many pages can she write in one minute? (fraction) pages per minute.
HELP I BEG!!
Answer:
She can write 2 pages and 4/5 extra.
Step-by-step explanation:
We know that she has already written for 1/14 of a minute. Now we need to turn that fraction into a whole, because the problem is asking for a whole minute.
___ x 1/14 = 1?
14
Now we take the 1/5, and multiply it by the 14 to see how much she writes in a minute.
1/5 x 14 = 14/5
Last we simplify.
14/5 = 2 4/5
