PLEASE HELP!!! YOU GET 10 BRAINLIST!!!! PLEASE SHOW ALL OF YOUR WORK/HOW YOU GOT THE ANSWER!!!
Answer:
The Answer is: x=10 or anything less than 10, but if there are no answer choices, I recommend you just say 10 or under 10
Step-by-step explanation:
2/3(3x-6)+1 = 15=
(2x-4)+1 = 15 =
(2x-5) = 15 =
(2x) = 20 =
x = 10 or less
Its kinda complicated, first ignore the less than or greater than sign and change it to an equal to sign now simplify it by doing order of operations, normally parenthesis goes first but there's nothing you can do in there, so since its 2/3(3x -6), you will need to divide everything in the parenthesis by 2/3, subtract everything by a third of its amount, and your outcome will be (2x -4) + 1, now add the one to 4 and you will now get 5 and your new outcome will be (2x-5) = 15. Now that its simplified instead of subtracting the 5 you will be adding it to the opposite side, which sounds complicated so let me explain, since you can't simplify it further, your basically summing it up on the opposite side therefore, with this, you will get (2x) = 20, same goes with multiplication too, you sum it up on the other side by its opposite, which is division, so instead of multiplying 2 by x, your dividing 20 by 2, and you will get as your new outcome, and your answer x = 10 or of which less than 10 because 10 is greater than or equal to x.
Therefore, your final answer is x is less than or equal to 10.

1A coat is on sale. The original price of the coat is $82. The sale price is $74.50.
A. What is the discount amount?
B. What is the discount expressed as a percent change?
somebody please help me.
Answer:
A. $7.50
B. 9.15%
Step-by-step explanation:
Difference of 82 and 74.50 = |82 - 74.50|/((82 + 74.50)/2) = 7.5/78.25 = 0.095846645367412 = 9.5846645367412%
74.50 is a 9.1463414634146% decrease of 82.
Percentage of decrease = |82 - 74.50|/82 = 7.5/82 = 0.091463414634146 = 9.1463414634146%
{HELP ASAP!!} These two pentagons are similar.
Two units are added to each side of pentagon FGHIJ. Which statement about this situation correctly applies the concept of similarity?
A. The pentagons remain similar because the same length was added to each side of FGHIJ.
B. The pentagons may not be similar because changing the lengths by adding the same number of units doesn’t preserve similarity.
C. The pentagons are not similar because changing the side lengths of FGHIJ will also change the angle measures.
D. The pentagons remain similar because similarity is not affected when the lengths of a figure are changed.
Answer:
b
Step-by-step explanation:
The pentagons remain similar because similarity is not affected when the lengths of a figure are changed. Option d is correct.
Two pentagons are given, 2 units add to each of the sides of both the pentagons. whether the two pentagons are similar or not is to be determined.
Pentagon is defined as a 5 sided polygon have equal lengths of sides and vertices make 72° at the center
Two pentagons are similar if 2 units are added to both the lengths of sides of the pentagon it will not affect their similarities. Because the ratio of the side to 1 pentagon to other pentagon remains the same on all sides.
Thus, the pentagons remain similar because similarity is not affected when the lengths of a figure are changed.

Find the simple interest earned on a deposit of $2,800 that earns 2% annual interest after 5 years
Answer:
$280
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year,
then, solving our equation
I = 2800 × 0.02 × 5 = 280
I = $ 280.00
The simple interest accumulated
on a principal of $ 2,800.00
at a rate of 2% per year
for 5 years is $ 280.00.

When Eric’s income was $500 per week he bought 10 fish tacos per week, but when his income increased to $600 per week he started buying 15 fish tacos per week. What is Eric’s income elasticity of demand for fish tacos
Answer:
2.5
Step-by-step explanation:
Eric's demand for fish tacos increased by 50% when his income increased by 20%.
What is income elasticity?An income elasticity of demand greater than 1 indicates a normal good, while an income elasticity of demand less than 1 indicates an inferior good.
To calculate the income elasticity of demand for fish tacos, you need to divide the percentage change in the number of fish tacos demanded by the percentage change in income.
As per the question, the number of fish tacos demanded increased by 50% (15 - 10 = 5, and 5 / 10 = 0.5), and the income increased by 20% ($600 - $500 = $100, and $100 / $500 = 0.2).
So, the income elasticity of demand is 0.5 / 0.2 = 2.5.
This means that when Eric's income increased by 20%, the number of fish tacos he demanded increased by 50%.

At a grocery store, the price of 4 cans of tuna is $3.88.
At this rate, how much would 7 cans of tuna cost?
A) $6.79
B) $6.88
C) $7.21
D) $7.76
Answer:
A. 6.79
Step-by-step explanation:
4/3.88= 0.97 per can
0.97*7=6.79
Answer:
Option A: $6.79 is the correct answer.
Step-by-step explanation:
Given that:
Cost of 4 cans of tuna = $3.88
Cost of 7 cans of tuna is to be find.
We will find the unit rate.
Unit rate = [tex]\frac{Cost\ of\ cans}{Number\ of\ cans}[/tex]
Unit rate = [tex]\frac{3.88}{4}[/tex]
Unit rate = $0.97 per can
Cost of 7 cans = 7*0.97
Cost of 7 cans = $6.79
Hence,
Option A: $6.79 is the correct answer.
