Define a variable, set up an equation, then solve.
Sean and Evan are selling rolls of wrappign paper to raise money for new football uniforms. Evan has sold seven more than one-half the number of rolls that Sean has. If they have sold a total of 121 rolls, how many has Evan sold?
x - Rolls sold by Evan
Let x be the number of rolls sold by Sean.
We are given that Evan has sold 7 more that one-half the number of rolls that Sean sold.
Evan has sold 1/2x + 7 rolls.
Therefore, we have:
x + (0.5x + 7) = 121
1.5x = 121 - 7
x = 114/1.5
x = 76

Answer:
15/16 liters
Step-by-step explanation:
Let x=number of liters
Let y= container
Equation: 5/8 x = 2/3 c
Multiply both sides by 3/2 --- c = (5/8x) x (3/2)
The volume of the container is 15/16 liters

4^2÷ 2^1
A. 8
B. 2
C. 0
D. 44
Answer:
A. 8
Step-by-step explanation:
Use PEMDAS
E for exponents (4^2)/(2^1)
4^2 = 4 * 4 = 16
2^1 = 2
D for division
16/2 = 8
So the answer is A
Hi!
Let's solve it together.
4^2 is just 4x4,
4 x 4 = 16
Next, 2^1.
2^1 is just 2, so the answer is 2.
Now, we divide 16 and 2.
16 ÷ 2 = 8
So, the answer is A.Hope this helps!~~~PicklePoppers~~~What is the sum of the fractions? Use the number line and equivalent fractions to help find the answer.

PLEASE HELLP 100 POINTS ARE AVAILABALE
Answer:
A
Step-by-step explanation:
4 (0.5x + 2.5y - 0.7x - 1.3y + 4)
Use commutative property with like terms 4( 0.5 x - 0.7x + 2.5y - 1.3 y + 4)
Combine like terms 4 (-0.2x + 1.2y + 4)
Use distributive property -0.8x + 4.2y + 16
Zach bought 5 DVDs for $14.95 each. How much did he pay, NOT including sales tax
Answer: $71.76
Step-by-step explanation: You're going to multiply 14.95 by 5 then you get your 74.75 then subtract 2.99 because 14.95 was the total for each you would divide 14.95 by 5 which equal 2.99 then divide then by each other 74.75 diveded by 2.99 then get you answer.
HELP PLZ ND THX U?!?!?!?!?!?!?!?!?!
Answer:
U = 1
Answer = 6
Step-by-step explanation:
We can do really any number. But in this case, we are gonna do 1. So, it would look like (7 x 1) - 1. It would look like that because we know that 7u is equal to 7 times U or in this case, 7 times 1. So, we know 7 x 1 is 7. Now, we do 7 - 1 since U = 1, and we get our answer of 6.
Please answer the picture
Answer:
B. not equivalent

Question
A map of a farm is shown in a coordinate plane in which the coordinates are measured in yards. The map shows the barn at (-5, 4). A well is dug at (-5, y). What are two values of y such that the barn is 30 yards from the well?
Answer:
y-34 or y-30
Step-by-step explanation:
Use the distributive property & multiply the 2x + 3 inside the parenthesis using the 4 outside the parenthesis.
Then, multiply them to both sides, to get . (8x+12) = yDistribute by multiplying y with 8x + 12 using the distributive property.Your final result will be 8xy + 12y / 5Learn more about distributive property here: brainly.com/question/2807928

Zack fills bird feeders with birdseed. Each bird feeder holds 2 1/2 cups of birdseed. Zack’s scoop holds 1/4 cup.
How many scoops will Zack use to fill both bird feeders?
1. How many cups of seed does Zack need to fill both bird feeders? Show how you found your answer
2. Write an expression for the number of scoops Zack needs to fill both feeders
3. Evaluate the expression to find the number of scoops Zack needs. Show your work
Answer:
1.) 5
2.) 0.25x=5
3.) 20
Step-by-step explanation:
1.) 2.5 (same as 2 1/2) x2 ("both bird feeders")= 5 cups needed
2.) 0.25x=5 x= amount of cups needed (0.25 is the same as 1/4)
3.) 5÷0.25= 20

A large pool has a faucet to allow water to enter the pool and a drain to allow water to leave the pool.
Each minute, the faucet allows 12 1/5 gallons of water to enter the pool, and the drain allows 15 2/3 gallons to leave the pool.
What is the change in the amount of water in the pool after 1 1/2 minutes?
Enter your answer as a simplified mixed number by filling in the boxes.
Answer:5 1/5
Step-by-step explanation:
12 1/5 =12.2 as a decimal
12.2 x 1.5 = 18.3
15 2/3 x 1.5 = 23.5
23.5 -18.3 =5 1/5
Describe in detail how you would create a number line with the following points: 4, 1.25, the opposite of 3, and – (–2fraction of one-half). Please be sure to describe on which tick marks each point is plotted and how many tick marks are between each integer. It may help for you to draw this number line by hand on a sheet of paper first. brainleist for right answere if u dont answer propoly i will report!
Answer:
Given : points 4 , 1 ,25 , opposite of 3 , -1/2
To Find : draw on Number Line
Solution :
Numbers with a negative sign are less than zero
Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.
+ sign numbers can be denoted as simply numbers
On a number line the number increases as we move to the right and decreases as we move to the left.
1 : Draw a line and mark some points at equal distance on it as shown in the figure below Mark a point as zero on it. Points to the right of zero are positive integers and are marked simply 1, 2, 3 and so on , while points to the left of zero are negative integers and are marked – 1, – 2, – 3 and so on
2. Go 4 unit on right sides from Zero to show 4
3. Go 3 units on Left from zero to show opposite of 3
4. Divide number line between 1 & 2 in 4 Equal parts and go 1 part right of 1
5. Divide number line between 0 & -1 in 2 Equal parts and go 1 part left of 0

A system of equation is shown.
5x+2y=245
y=x+6
Enter a numeric value to complete the solution of the system.
Answer:
y = 245 / 7, x = 29
Step-by-step explanation:
make both into ax + by = c format which is
Math:
5x + 2y = 245
-5x + 5y = 30 <== 5 (- x + y = 6) to cancel out the x since it has a negative already.
[(Side Note) if both were positive then you would need to do
EX: - 5 (- x + y = 6)]
Continued:
7y = 275 ==> 7y/7 = 245/7
y = 245 / 7
Plug it in the most convenient one which has the equation y = x + 6
and tweak it a bit
x = y - 6
x = 245 / 7 - 6 ==> 245 / 7 - 42 / 7
x = 203 / 7 ==> 29
