A game store charges a monthly membership fee of $7.50, but then the charge to rent a game is only $1.00. Another store has no membership fee, but that store charges $2.00 to rent a game. How many games need to be rented each month for the total fees to be the same from either store?

Answers

Answer:

6 games.

Step-by-step explanation:

Given that,

Monthly membership fee of store 1 is $7.5, but then the charge to rent a game is only $1.00

Another store has no membership fee, but that store charges $2.00 to rent a game.

Let there be n games needed to be rented each month for the total fees to be the same from either store.

Cost of first store = $7.50+$1.00n

Cost of another store = $2.00

If cost equals,

$7.50+$1.00n=$2

n=5.5 [tex]\approx[/tex] 6

Hence, 6 games needed to be rented each month.

2(x + 9) = 4(x - 7) + 2

Answers

Answer:

x = 22

Step-by-step explanation:

Step 1: Write equation

2(x + 9) = 4(x - 7) + 2

Step 2: Solve for x

Distribute: 2x + 18 = 4x - 28 + 2Combine like terms: 2x + 18 = 4x - 26Subtract 2x on both sides: 18 = 2x - 26Add 26 to both sides: 44 = 2xDivide both sides by 2: 22 = xRewrite: x = 22

Step 3: Check

Plug in x to verify it's a solution.

2(22 + 9) = 4(22 - 7) + 2

2(31) = 4(15) + 2

62 = 60 + 2

62 = 62

Answer:

x=22

Step-by-step explanation:

2x+18=4x-28+2

2x+12=4x-26

2x+44=4x

44=2x

22=x

The first five terms of the sequence are (Use a comma to separate answers.)

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Number of cars sold in first month = 4900

Sales drop by 100 cars per month for the first year:

A(x) = a - 100(x - 1)

No = sale In first month = 4900

First five months

Ist month :

a = 4900

2nd :

4900 - 100 = 4800

3rd :

4800 - 100 = 4700

4th:

4700 - 100 = 4600

5th:

4600 - 100 = 4500

First five terms : (4900,4800,4700,4600, 4500)

Predicted sales for 12th month :

A(12) = 4900 - 100(12 - 1)

A(12) = 4900 - 1100

= 3800

Total sales for the first year:

4900+4800+4700+4600+4500+4400+4300+4200+4100+4000+3900+3800) =

Your homework grades are 92, 87, 74, 96, 83, 88, 91, 82, and 85. What score on your next homework will make the median and the mode equal? List the scores in order from least to greatest. You can use the strategy Systematic Guess and Check to help you find the solution.

Answers

Answer:Next  homework  Score should be  87.

Step-by-step explanation:

STEP 1

Listing the scores in ascending order ie from least to greatest gives

74, 82, 83, 85, 87, 88, 91,92, 96

STEP 2

we find the median--- The median score is the score  that is in the middle of the set of results when arranged from lowest to highest as we have done above , which give  us 87 as the median.

74, 82, 83, 85,   87,    88, 91,92, 96

Also Mode is the score with the highest frequency , ie the score which appears more than other numbers. For now we have no mode as all the numbers occurred once

Therefore in next exam, I should get a score of 87,  making my scores to become

74, 82, 83, 85, 87, 87, 88, 91,92, 96

Now my mode becomes 87 ( highest frequency of  occurrence ) and

My median becomes (87+ 87)/2 = 87  ( with the addition of a new score the total score become ten, which is now even, so we divide the addtion of the two middle numbers by 2 )

I really need help with this one

Answers

Answer:

28

Step-by-step explanation:

Since B is the midpoint of AC, that means AB = BC. That means 3x+4 = 5x-6. We can now set up an equation to solve for x:

3x+4 = 5x-6

3x+10 = 5x

10 = 2x

x = 5

Now that we know what x is, we can just plug x into the expression of AB and multiply it by 2:

(3*(5)+4)*2

=(15+4)*2

=19*2

=28

(side note: we could have plugged x into the expression of BC as well, but in this case plugging it into AB tends to be easier to solve)

Therefore, the length of AC is 28.

If b= 40 degrees and c= 30 degrees, what is the measure of d?

Answers

Answer:

It would be D. 110 degrees

Step-by-step explanation:

A triangle is always equal to 180 degrees. So, if you add b + c, you get 70 degrees. Subtract that from 180, and you get 110. Hope this helped!

Answer:

a = 110 degree

d= 70 degree

Step-by-step explanation:

a+b+c = 180. (being sum of all interior angle of a triangle is 180 degree)

a+40+30 = 180

a=180-70

a = 110

Similarly,

a+d=180. (being supplementary angle)

110+d=180

d= 70

An arithmetic series contains 14 numbers. The first number is 12. The last number is 38. What is the sum of the series?
A. 312

Answers

Answer:

B. 350

Step-by-step explanation:

done on edge

The sum of the sequence is 350 if the arithmetic series contains 14 numbers. The first number is 12. The last number is 38 option (B) is correct.

What is a sequence?

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

It is given that:

An arithmetic series contains 14 numbers.

The first number is 12.

The last number is 38.

As we know, the sum of the arithmetic sequence or series is given by:

S = (n/2)(a + l)

Here, S is the sum of the AP

n is the number of terms

a is the first term

l is the last term

n = 14

a = 12

l = 38

S = (14/2)(12 + 38)

S = (7)(50)

S = 350

Thus, the sum of the sequence is 350 if the arithmetic series contains 14 numbers. The first number is 12. The last number is 38 option (B) is correct.
