Answer:
37 boxes
Step-by-step explanation:
you should try and write each of the steps into an equation of x. Where x is the boxes she started with
so, she had x boxes, she bought 7 (that's addition) and then half of those boxes (that's division) got destroyed in the fire and she has 22 left (that's your total).
you can write the equation like this:
(x+7)/2 = 22
then, you solve
(x+7) = 44
x = 37
she originally had 37 boxes

Answer:
11
Step-by-step explanation:
A is -7 and b is -4 if you add them it would be positive 11 because a negative plus a negative is a positive. Here's this to keep in mind:
+(+) Two like signs become a positive sign 3+(+2) = 3 + 2 = 5
−(−) 6−(−3) = 6 + 3 = 9
+(−) Two unlike signs become a negative sign 7+(−2) = 7 − 2 = 5
−(+) 8−(+2) = 8 − 2 = 6

Jerome hiked three-fourths of a mile in two-thirds of an hour. What was his hiking speed in miles per hour?
The value of his hiking speed in miles per hour will be;
⇒ Speed = 9/16 miles per hour
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Jerome hiked 3/4 of a mile in 2/3 of an hour.
Now,
Since, Jerome hiked 3/4 of a mile in 2/3 of an hour.
Hence, We can formulate;
⇒ Speed = Distance / Time
⇒ Speed = 3/4 / 2/3
⇒ Speed = 3×3 / 4×4
⇒ Speed = 9/16 miles per hour
Thus, The value of his hiking speed in miles per hour will be;
⇒ Speed = 9/16 miles per hour

Ruben bought 666 comic books for \$21$21dollar sign, 21. Each comic book was the same price.
what was the cost for 1 comic book
9514 1404 393
Answer:
$3.50
Step-by-step explanation:
If c represents the cost of one comic book, the transaction can be written as the equation ...
6c = $21
Dividing by 6, we get ...
c = $21/6 = $3.50
The cost for 1 comic book was $3.50.
_____
You know that the total cost of a transaction is the sum of the costs of each part. When all the parts have the same value, we can multiply the cost of one part by the number of parts.

She charges an initial fee of $10 for each
rental and an hourly rate of $4. Which of
the equations below shows the amount
y that Rashida charges for a bike rental
that lasts x hours?
A. y=10+4x
B. y=10+4x
C. y=4+10x
D.y=4+10x
Answer:
A
Step-by-step explanation:
Because the 10 is bigger then the 4 so when you do the math (y) will equal the answer of A which its 14
Answer:
The answer is y=10+4x
Step-by-step explanation:
so because x is represented by hours you dont know how many hours someone rents the bike so x and ten dollars is a set amount so it would stand alone.
Amy and Stephanie were playing a number game. Amy picked a number and told Stephanie that if she added 9 to the number and multiplied the sum by 2, it would equal 8. Which equation could Stephanie use to find the number, x?
Answer:
4 (x + 7) = 8
Step-by-step explanation:
4 (x + 7) = 8 Because you add 7 to Amy's number then multiplied by 4 which equals 8

. During a volleyball training session, Idalie drank twice as much water as Adamaris, and Jonathan
Arank 100 mL more water than Idalie. Between them they drank 3 liters of water. How much water
did Adamaris drink?
Answer:
Step-by-step explanation:
Let's say I = amount of water Idalie drank,
A = amount of water Adamaris drank
J = amount of water Jonathan drank.
We are told Idalie drank twice as much water as Adamaris. You can write it as:
Idalie = 2 times Adamaris
I = 2A
Then we are told Jonathan drank 100ml more than Idalie. So
Jonathan = 100 + Idalie
J = 100 + I (and we know I = 2A)
J = 100 + 2A
Between them they drank 3 liters (3L = 3000ml) of water.
Idalie + Adalie + Jonathan = 3000
I + A + J = 300
So since we know I = 2A and J = 100 + 2A, we can put it into the equation above:
2A + A + 100 + 2A = 3000
Gather the like terms and you get:
5A + 100 = 3000
Subtract 100 from both sides.
5A = 3000 - 100 = 2900
To find A, divide both sides by 5
A = 2900/5 = 580
This means Adamaris drank 580ml of water

if the midpoint is located at (6,-2) and one endpoint is at (1,7), what is the coordinates of the other endpoint?
Answer:
(11, -11)
Step-by-step explanation:
The coordinates of the midpoint are the average of the endpoint coordinates.
6 = (x + 1) / 2
x = 11
-2 = (y + 7) / 2
y = -11

Step-by-step explanation:
You would change 4 to 4/1 and then set up the equation
4/1 x -2/3
4x-2=-8
1x3=3
you would then get -8/3 which is then turned into -2 2/3

Mr. West estimated a mass to be 265g, but upon carefully measuring it, found the actual mass to be 240g. What was the percent error?
Answer:
The answer is 10.42 %Step-by-step explanation:
The percentage error of a certain measurement can be found by using the formula
[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]
From the question
actual mass = 240 g
error = 265 - 240 = 25
So we have
[tex]p(\%) = \frac{25}{240} \times 100 \\ = 10.41666666...[/tex]
We have the final answer as
10.42 %Hope this helps you

20=5x-13=6x what is x equaled to
HELP ASAP
20=5x-13+6x
We move all terms to the left:
20-(5x-13+6x)=0
We add all the numbers together, and all the variables
-(11x-13)+20=0
We get rid of parentheses
-11x+13+20=0
We add all the numbers together, and all the variables
-11x+33=0
We move all terms containing x to the left, all other terms to the right
-11x=-33
x=-33/-11
x= 3
Answer:
3
Step-by-step explanation:
First, write the equation.
20=5x-13+6x Combine like terms on the right side.
20=11x-13 Add 13 on both sides.
+13 +13
33=11x Divide both sides by 11.

what is the simplification for this ? 2y+3=4y+2
Answer:
2y-1
Step-by-step explanation:
Answer: y = 1/2 in decimal form = 0.500
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*y+3-(4*y+2)=0
olve : -2y+1 = 0
Subtract 1 from both sides of the equation :
-2y = -1
Multiply both sides of the equation by (-1) : 2y = 1
Divide both sides of the equation by 2:
y = 1/2 = 0.500
