Answer:

x = 19, TS = 22

Step-by-step explanation:

Use ratios to solve for x. Corresponding sides have same ratio.

Q1

(x + 5)/30 = (36 - 20)/20(x + 5)/30 = 16/20 = 4/55(x + 5) = 4(30)5x + 25 = 1205x = 95x = 19

Q2

(5x - 2)/(3x + 1) = 39/26(5x - 2)/(3x + 1) = 3/22(5x - 2) = 3(3x + 1)10x - 4 = 9x + 310x - 9x = 3 + 4x = 7

TS = 3x + 1 = 3(7) + 1 = 22

An iPad that was originally on sale for $1075 is now on sale for $ 623.50. What is the percent markdown( percent decrease)?

Answers

Answer = 58%

Explanation : you would have to set up a portion table were the sale amount (623.50) would go and the original/total price would go (1075$) and since you are trying to find the % you would put x over 100 , and then cross multiply while it’s set up so 623.50 times 100 =62,350 and you would take the answer and divide it by 1075x which would get you to 58 and that would equal x .

Answers

Well, we are asked to simplify and solve this multiplication problem.
So, at first, this looks a little bit tricky but, we can actually break it down and then multiply with easy numbers.
First off, we can multiply 4 by 9 which is 45 however, we still have that major 50 so, to make it easier, we can just change the 50 to a 5 and then add the 0 at the end when we get our answer.

45 * 5
= 225

Lastly, we just need at put and add a zero (0) to our answer so, in conclusion, the answer to this question is: 2250.

C) (5, 7) D) (-7, 7)

Answers

Answer:

Step-by-step explanation:

-3x – 2y = -17

9x + 2y = 23

____________+

6x = 6

x = 6/6

x = 1

9x + 2y = 23

2y = 23 - 9

2y = 14

y = 14/2

At a local fitness​ center, members pay a ​$10 membership fee and ​$4 for each aerobics class. Nonmembers pay ​$6 for each aerobics class. For what number of aerobics classes will the cost for members and nonmembers be the​ same?

Answers

Answer:

5 classes

Step-by-step explanation:

Let x represent the number of aerobics classes

Create an equation that sets the member and nonmember prices equal to each other, then solve for x:

4x + 10 = 6x

10 = 2x

5 = x

So, after 5 aerobics classes, the costs will be the same.

Your friend needs your help. His parents have told him that it is time for him to start paying for his own cell phone. After completing some research on the internet, you have narrowed down his options. Option 1 charges $0.30 for each cell phone call and $25 for unlimited text messaging. Option 2 charges a flat rate of $40.

Which plan is the best option?​

Answers

Answer:

For less than 50 calls, option 1 is the best, while for more than 50 calls, option 2 is the best.

Step-by-step explanation:

Option 1:

For n calls, the cost is given by:

[tex]C_{1}(n) = 25 + 0.3n[/tex]

Option 2:

The cost is flat of 40, so [tex]C_{2}(n) = 40[/tex]

Which plan is the best option?​

Depends on the number of calls, as for a high number, [tex]C_1[/tex] will be higher than [tex]C_2[/tex]. We have to find this number. So

[tex]C_{1}(n) > C_{2}(n)[/tex]

[tex]25 + 0.3n > 40[/tex]

[tex]0.3n > 15[/tex]

[tex]n > \frac{15}{0.3}[/tex]

[tex]n > 50[/tex]

This means that for less than 50 calls, option 1 is the best, while for more than 50 calls, option 2 is the best.

x-5y=-15

+5y on both sides

x=5y-15

Answer:

x = -10

y = 1

Step-by-step explanation:

x - 5y = -15

x - 2y = -12

__________--

-3y = -3

y = -3/-3

y = 1

x - 2y = -12

x - 2(1) = -12

x - 2 = -12

x = -12 + 2

x = -10
