Write an expression to represent the income of the fundraiser in the following paragraph
Write an expression to represent the profit of the fundraiser.
The varsity basketball team is selling t-shirts as a fundraiser. It costs them $100 to have the shirts professionally designed, and they have to pay $5 for each shirt. They plan on selling the shirts for $10 each.
I already got that the expression that represents the expenses of the fundraiser would be -5x+100. But I was kinda confused about the other ones :-/ Any help would be appreciated (-:
Answer:
10x>5x+100
Step-by-step explanation:
it says expression not equations so its < , >,
The profit would be on one side and the expenses on the other
No negatives
so it would be 5 times X (the amount of shirts) plus the base fee of $100
and they plan on selling it for 10$ each so (10x) is the profit
X = number of shirts

1/2 ( x - 4 ) = 1/3 ( x + 2)
pls help me
Answer:
x=16
Step-by-step explanation:
1/2 ( x - 4 ) = 1/3 ( x + 2)
distribute both sides
1 /2 (x−4)= 1/ 3 (x+2)
( 1 /2 )(x) + ( 1/ 2 )(−4) =( 1 /3 ) (x)+( 1/3 )(2)(Distribute)
1 /2 x+−2= 1 /3 x+ 2 /3
1 /2 x+−2= 1 /3 x+ 2 /3
Step 2: Subtract 1/3x from both sides.
1/2x -2 -1/3 x
x= 1 /3 x + 2/3 − 1/ 3 x
1 /6 x−2= 2/ 3
Step 3: Add 2 to both sides.
1 /6 x −2+2= 2/ 3 +2
1 /6 x = 8 /3
Step 4: Multiply both sides by 6.
6*( 1/6 x) =6*( 8 /3 )
x=16

8. 8y = 5.6
9. x ➗ 15.2 = 3
10. u ➗ 8.7 = 12
11. 31.4 = 3.14y
Step-by-step explanation:
8. You divide each side by 8
[tex] \frac{8y}{8} = \frac{5.6}{8} [/tex][tex]y = \frac{5.6}{8} [/tex]9. You multiply each side by 15.2
[tex]x = 3 \times 15.2[/tex]X=45.610. You multiply bith sides by 8. 7
[tex]u= 12 \times 8.7[/tex]11. You divide both sides by 3.14
[tex]3.14y = 31.4 \\ y = \frac{31.4}{3.14} \\ y = 10[/tex]Hope this helps, have a wonderful day

80 L is what percent of 400 L tank
Answer:
50%
Step-by-step explanation:
BRAINLIEST PLEASE
Answer:
the percentage of 80L from 400L is 20%
Step-by-step explanation:
in order to find the percentage of something you need to divide the total amount from the number you want to find the percentage of:
80 / 400 = 0.2
we now multiply 0.2 by 100 to turn it into a percentage:
0.2 * 100 = 20%
2x^2+15x=8
factor or solve as indicated, show all work.
please and thank u!
Answer: x= -8 or x = 1/2
Step-by-step explanation:
2x^2 + 15x = 8 Subtract 8 from both sides to let the whole equation equal 0
- 8 -8
2x^2 + 15x - 8 = 0 Now find two numbers that if you multiply them, their product will be -16 and their sum will be 15. An example is the numbers 16 and -1. 16 times -1 is -16 and 16 plus -1 is 15.
Rewrite the whole equation in this form,
2x^2 +16x - 1x - 8 = 0 Factor on the left side
2x ( x + 8) -1 (x + 8) = 0 Now factor out x + 8
(x + 8) (2x -1) = 0 Set each expression equal zero, because for the whole expression to equation to 0, either one of them or all of them have to equation zero.
x + 8 = 0 or 2x - 1 = 0
-8 -8 +1 +1
x = - 8 2x = 1
x = 1/2
Is the relation a function? If it is a function, state the domain and range. If not, circle or
highlight the part that causes it to not be a function.
Answer:
Please check the explanation.
Step-by-step explanation:
Writing this relation in set notation using curly braces:
{(1, 3), (2, 5), (3, -1), (4, 0), (5, 6)}
The relation clearly indicates that each input is related to exactly one output. In other words, there is no repetition of 'x' values.
Hence, this relation is a function.
We know that the domain is the set of all x values.
Thus, the domain is: {1, 2, 3, 4, 5}
We know that the domain is the set of all y values.
Thus, the range is: {-1, 0, 3, 5, 6}

Edward deposited $6,500 into a savings account 4 years ago. The simple interest rate is 5%. How
much money did Edward earn in interest?
Substitute the values into the equation.
Interest=$• • years
Edward earned $ in interest.
Answer:
Edward earned $1300 interest in 4 years.
Step-by-step explanation:
Principal Amount = Initial Investment = $6500
Time t = 4 years
Interest rate r = 5% = 0.05 (it is taken in decimal i.e 5/100 = 0.05)
We need to find interest.
The formula used is: [tex]Interest= Principal\times r \times t[/tex]
Putting values and finding Interest
[tex]Interest= Principal\times r \times t\\Interest=6500\times 0.05 \times 4\\Interest= 1300[/tex]
So, the interest = $1300 in 4 years.
Edward earned $1300 interest in 4 years.

Use the graph below for this question: A 6 4 3 What is the average rate of change from x = -1 to x = -2? (1 point) 2 - 2 4 -1
Answer:
- 2
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 2, - 1 ] , then
f(b) = (f(- 1) = 5 ← corresponding value of y (- 1, 5 )
f(a) = f(- 2) = 7 ← corresponding value of y (- 2, 7 ) , thus
average rate of change = [tex]\frac{5-7}{-1-(-2)}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2
