The original price of the item was $70 if Joyce paid $31.50 for an item at the store that was 55 percent off the original price.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
Let x be the original price of the item. Then, we can write the equation:
x - 0.55x = 31.50
from the given expression we need to solve the value of x to get the original price if Joyce paid $31.50 for an item at the store that was 55 percent off the original price
Simplifying the given equation, we get:
0.45x = 31.50
Dividing both sides by 0.45, we get:
x = 70
Therefore, the original price of the item was $70.

Which equation does the graph below represent
Answer: The answer is y=-3x
Step-by-step explanation: You can see in the picture that the line is going down which represents a negative slope so you can eliminate C and D. Now you are left with A and B. 1 unit up is equal to 3 so the rise over run is -3/1 and that translates to Y=-3x answer B
Jaden places potatoes with a mass of 0.55 kilograms on a grocer's scale. The spring is displaced by 1.2 centimeters. He then places some onions on the scale that displace the spring by 0.67 cm. What is the mass of the onions (1 kg=9.8 N)? 5.39 kg 3.01 kg 0.67 kg 0.31 kg
Answer:
.31 kg
Step-by-step explanation:
F=kx
F = the force of the spring
k = the spring constant
x = the spring displacement (stretch or compression)
we also know that 1 kg = 9.8 N which also means that 9.8(kg)=F
let's first find the force of the first problem, which is .55 kg. Using the formula 9.8(kg)=F we can do 9.8(.55)=F which would mean the force is 5.39 N
so 5.39=k(1.2 centimeters)
Now we need to convert centimeters to meters. This would make 1.2 into .012m. Now our problem is 5.39=k(.012)
divide 5.39 by .012 to get 449.17
our k is 449.17
Now for our problem, we are going to find the mass.
Do this by putting what we already know into the problem.
F=449.17(.67 centimeters)
Now we already know we need to convert centimeters to meters which will make our formula F=449.17(.0067m)
This will result in F=3.01 but the problem is asking for mass, not force.
Use the formula 9.8(kg)=F
9.8(kg)=3.01
kg=.31
solution: .31 kg
Trucks must haul between 150,000 yd' and 180,000 yd of earth each day to create a new
water park near Universal Studios in Orlando, Florida. The trucks can haul 10.000 yd per day
and 120,500 yds have already been brought to the site. How many days are needed to
complete this job?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Range which must be hauled by trucks :
150,000 - 180,000 yds of earth
Haul per day = 10000 yds
Already removed = 120,500
We can express the problem as an inequality:
Using y = number of days
150,000 ≤ (10000y + 120,500) ≤ 180000
150,000 ≤ (10000y + 120,500)
150000 - 120500 ≤ 10000y
29500/10000
y = 2.95 days
10000y + 120,500 ≤ 160000
10000y ≤ 160000 - 120500
y = 39500/10000
y = 3.95
2.95 ≤ y ≤ 3.95

Ellie bought cookies and cupcakes from Publix for $102.44. If she spent $36.44 on cookies and the cupcakes are $11 per box, which equation represents this situation?
A)11x - 36.44 = 102.44
B)102.44x + 11 = 36.44
C)11x + 36,44 = 10244
D)102.44 + 36.44x = 11
Answer:
C
Step-by-step explanation:
She spent $102.44 in total.
She spent $36.44 on cookies.
And $11 per box of cupcakes.
This means that she knows the exact amount she spent on cookies and in total so now to find out how much she spent on cupcakes, she subtracts $36.44 from $102.44($66) and then divides 66 by 11(6). So if you needed the problem solved x=6.

Lenox ironed of the shirts over the weekend. She plans to split the remainder of the work equally over the next 5 evenings. If Lenox has 40 shirts, how many shirts will she need to iron on Thursday and Friday? Do not include units in your answer.
Answer: 16
Step-by-step explanation:
Total shirts = 40
Number of evenings = 5
If we split the remainder of the work equally over the next 5 evenings.
then, the number of shirts she will need to iron on each evening = [tex]\dfrac{40}{5}=8[/tex]
Number of shirts need to buy on Thursday and Friday = 2 (8) = 16
Hence, the number of shirts she need to iron on Thursday and Friday = 16
