How can you use the properties of equality to write equivalent equations?
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable.
a = b and c ≠0, then a c = a c . Another example Consider the equation 12 = 12. Divide both sides by 4.
The price, P, of a sweater was discounted by 10% in
February. Because the sweater did not sell by the end of
the winter season, it was discounted by another 20% in
March. In terms of P, what was the price of the sweater
after the discount in March?
Answer:
In terms of P, the price of the sweater after the discount is 0.72P.
Step-by-step explanation:
Since the price P would represent 100% and the price was discounted by 10%, you can calculate 10% of 100% and subtract that amount, which would be:
100*10%=10
100-10=90%
This means that the price paid would be 90% of P. Then, the statement says that the price was discounted by another 20%. So, you have to calculate 20% of the price and subtract that amount from the price:
90*20%=18
90-18=72%
According to this, this means that in terms of P, the price of the sweater after the discount is 0.72P.

X+36 is less than 40 write equation
Answer:
x<4
Step-by-step explanation:
x+36 is less than 40
x+36<40
Subtract 36 from both sides
x<4This equation means, that in order for the equation to be true, x must be less than 4.
Answer:
x<4
Step-by-step explanation:
x+36=40
you do 36- 40 and get 4 then it would be x<4

A person Rents a canoe for 4 Hours and paid a total of $36. of Renting a canoe costs am initial fee of the $2 Plus an additional amount for each hour the canoe is rented,which graph represents the total cost,y, in dollars of renting a canoe for x hours
Answer:
Additional fee or hour = $8.5
y = $2 + 8.5x
Step-by-step explanation:
Given that :
Total paid = $36
Number of hours = 4
Initial rental fee = $2
Additional fee per hour = a
Total amount = initial rental fee + additional fee per hour * number of hours
36 = 2 + 4a
36 - 2 = 4a
34 = 4a
a = 8.5
Hourly fee = $8.5
Therefore, the cost formula
y = initial fee + regular fee * number of hours
y = $2 + 8.5x

a triangle's angles all add up to 180. take 51 and 39 away from 180 and you get 90
Answer: 90 degrees
Step-by-step explanation:
Theorem:
a+b+c=180 degrees
39 degrees + 51 degrees + x degrees = 180 degrees
39 + 51 = 90
180 - 90 = 90

Answer:
B. 31.62
Step-by-step explanation:
First, find the distance of the line using the distance formula, [tex]d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1} )^2 }[/tex]. Plug the two points (-1,0) and (5,2) into the formula and solve. This gives you 6.32, then this is only one line of a pentagon, which has 5 sides, so you need to multiply. Since you are finding the perimeter, which is all of the sides added together, multiply the one side by 5. 6.32*5=31.62.
Help me please I don't know how to solve this problem.
PLEASE HELP!?!?!?!?! In our amusement park that we built this week, the ride Diablo’s Domain had revenue of $250,000,000 in its first year as expected. The company paid $750,000 for insurance or $3 for every $1,000 in revenue. If the park is wildly successful and revenue increases by 25% in the second year and the rate of $3 for every $1,000 holds true, how much would it pay for insurance? Do you think it’s reasonable for insurance costs to increase proportionally? Why or why not?
Answer:
1) The amount to be paid as insurance if the revenue increases is $937,000
2) Yes because the total value of the risk insured and the likelihood of the occurrence of the risk both increases
Step-by-step explanation:
1) The given amount in revenue of the Diablo's Domain = $250,000,000
The amount the company paid as insurance = $750,000
The equivalent amount the company paid as insurance = $3 for every $1,000
The percentage amount in revenue the park revenue increases by = 25%
Therefore, the new amount in revenue = 1.25 × $250,000,000 = $312,500,000
The amount to be paid as insurance if the revenue increases = $315,500,000 × 3/1000 = $937,5000
The amount to be paid as insurance if the revenue increases = $937,000
2) It is reasonable for the insurance cost to increase proportionally when the items insured which leads to the increase in revenue increases because the value of the risk insured which is the event of settlement for losses increases as well as the probability of the risk occurring also increases.

Answer: It does because 1/3 is equal to 2/6. in order to add them, they have to have the same denominator. and if you add 2/6 to 1/6, you get 3/6. 3/6 is also equal to 1/2, if you divide both sides by 3.
