Andre came up with the following puzzle. “I am three years younger than my brother, and I am 2 years older than my sister. My mom's age is one less than three times my brother's age. When you add all our ages, you get 87. What are our ages?”

Jada writes this equation for the sum of the ages:

(x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87

Match the meaning to each term of the equation.


x

x + 3

(x - 2)

3(x + 3) - 1

87

Answers

Answer 1

Answer:

x = 13

Andre is 13, Andre's brother is 16, Andre's sister is 11, Andre's mom is 47

Answer 2

Answer:

x = 13

Andre is 13

Brother is 16

Sister is 11

Mom is 47

All together they are 87!

Step-by-step explanation:

x + x + 3 + x - 2 + 3x + 9 - 1 = 87

6x + 9 = 87

6x = 87 - 9

6x = 78

x = 78/6

x = 13

Which of the following is the graph of the inverse of f(x)=2x-3

Answers

Answer:

(-3,0) (0,1.5

Step-by-step explanation:

The answer choice which is the graph of the inverse of f(x)=2x-3 is; the graph of; f(x) = x/2 + 1.5.

What is the graph of the inverse of f(x)=2x-3?

It follows from the task content that the function given is; f(x)=2x-3.

Hence, to find the inverse function;

y = 2x - 3x = y/2 + 1.5.

Interchange the variables;

y = x/2 + 1.5.

On this note, it follows that the inverse function is;

f(x) = x/2 + 1.5

The graph of the inverse function therefore has points; (0, 1.5) and (2, 2.5) as points on the graph.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

The variable feet and yards are in direct proportion.

Let,

yard = k(feet).

a) A total of 27 parents will receive a call on the third round of calls. b) A total of 39 parents would've been called by the end of the third round of calls. c) There would have to be a total of between 5 and 6 rounds

Step-by-step explanation:

Every time the total number of parents call 3 people, the number of parents tripled in every round.

3 to 9 to 27 to 51 to 153 to 459

Since 153 and 459 are between 5 and 6 rounds, the phone calls will stop between those 2 rounds.

Step-by-step explanation:

Well it’s 12 to 30 so just put a fraction bar

and 12 divided by 30 is .4

Answer:

The answers are 12/30 and 10%

Step-by-step explanation:

It's 40% because the ratio of males to total students is 12 to 30, or 12:30, which is equal to 12/30.

The other answer is 10% because the ratio of males to total students is 3 to 30, or 3:30, which is equal to 1/10. Then you would do 100 divided by 10 which would give you 10 so it's 10%.

Many credit card companies charge a compound interest rate of 1.8% per month on a credit card balance. Miriam owes $550 on a credit card. If she makes no purchases or payments, she will go more and more into debt.

A. 550.00, 649.00, 765.82, 903.67, 1,066.33, ...

Please also explain how (steps) to get the answer, thank you!

Answers

Answer:

D. 550.00, 559.90, 569.98, 580.24, 590.68, ...

Step-by-step explanation:

So, her debt will increase of the interest rate of 1.8% on a credit card.

You have to multiply the rate by the amount that she owes. So, when you multiply 1.8% by $550 you get $9.90 amd you habe to add that to what she owes. You can't keep adding $9.90 because now her debt increased from $550 to $559.90. You now have to multiply $559.9 by 1.8% inorder to get her new amount of debt. If you multiply 1.8% by $550, then you are saying that she only has $550 as debt even though she now has $559.90 im debt. You must keep multiplying her new amount of debt by 1.8% to get her increasing monthly balance.

22+12= 34
