Answer: The cost of each game is $2.50

Step-by-step explanation:

Let's find the equations for each friend:

Friend 1:

Pays $3 for the shoes, and plays 3 games, then if X is the cost of each game, Friend 1 pays a total of:

$3 + 3*X

Friend 2:

This friend buys a soda for $0.50, and he plays 4 games, remember that the cost of each game was X. then this friend pays:

$0.50 + 4*X

And we know that both friends pay the exact same amount, then we can write:

$3 + 3*X = $0.50 + 4*X

And solve this for X.

We need to isolate X, then we can move all the terms with X to the right, and all the terms without X to the left:

$3 - $0.50 = 4*X - 3*X

$2.50 = (4 - 3)*X = X

This means the cost of each game is $2.50

Answer:

9/100.

Step-by-step explanation:

9% is equal to about 9/100. 9/100 is the simplest form.

Answer:

C) 3: 9

Step-by-step explanation:

27: 81

Ratios are same as fractions, that is why 27:81 = 27 / 81

Now that we go this fraction, let's make it an equivalent fraction:

(27 / 9) / (81/9)

=> 3/9

=> 3 : 9

Answer:

y

-47

-7

3

13

Step-by-step explanation:

Substitute the variable!

Basically you just substitute all the x values in.

------------------------------------------------------

x=-5

y=10(-5)+3

y=-50+3

y=-47

If x=-5, then y=-47

------------------------------------------------------

x=-1

y=10(-1)+3

y=-10+3

y=-7

If x=-1, then y=-7

------------------------------------------------------

x=0

y=10(0)+3

y=0+3

y=3

If x=0, then y=3

------------------------------------------------------

x=1

y=10(1)+3

y=10+3

y=13

If x=1, then y=13

------------------------------------------------------

Answer:

the solution to the system is (5,3)

Step-by-step explanation:

the first statement is True:    2(10) - 5(5) = -5

                                                20 - 25 = -5

                                                  -5 = -5

the second statement if False:    10 + 2(5) ≠ 11

the third statement is True

the last statement is False

Answer:

(−1)(5x+2)

Step-by-step explanation:

Step-by-step explanation:

5[tex]x^{2}[/tex] + 2x - 5x - 2

(5[tex]x^{2}[/tex] + 2x) (- 5x - 2)

x(5x + 2) -1(5x + 2)

Given:

Jeffery babysits for 4 dollars per hour and works as a math tutor for 7 dollars per hour.

He is only allowed to work 13 hours total per week.

He wants to make at least 65 dollars.

To find:

The system of inequalities to represent this situation.

Solution:

Let x be the number of hours he babysits per week and y be the number of hours h works as a math tutor.

He is only allowed to work 13 hours total per week.  It means sum of x and y must be less than or equal to 13.

[tex]x+y\leq 13[/tex]

He wants to make at least 65 dollars. It means total earnings must be greater than or equal to 65.

[tex]4x+7y\geq 65[/tex]

Number of hours can not be negative.

[tex]x\geq 0, y\geq 0[/tex].

Therefore, the required system of inequalities contains some equations,  [tex]x+y\leq 13,4x+7y\geq 65[/tex] and [tex]x, y\geq 0[/tex].

Answer:

14

Step-by-step explanation:

we know that w and 2 are the same here, so substitute w with 2: 7(2)

this means 7 times 2, and that is 14

Answer:

14

Step-by-step explanation:

If w=2

Plug in 7(2)... Multiply then you would have 14.

Answer:

1. 423     2. 71.25

Step-by-step explanation:

450.00-6%=423

75.00-5%= 71.25

Answer:

Simplifying

(4 + 2k) * 6 + 3k = 0

Reorder the terms for easier multiplication:

6(4 + 2k) + 3k = 0

(4 * 6 + 2k * 6) + 3k = 0

(24 + 12k) + 3k = 0

Combine like terms: 12k + 3k = 15k

24 + 15k = 0

Solving

24 + 15k = 0

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '-24' to each side of the equation.

24 + -24 + 15k = 0 + -24

Combine like terms: 24 + -24 = 0

0 + 15k = 0 + -24

15k = 0 + -24

Combine like terms: 0 + -24 = -24

15k = -24

Divide each side by '15'.

k = -1.6

Simplifying

k = -1.6

Answer:

Number of gallons consumed by first car = 15 gallons

Number of gallons consumed by second car = 25 gallons

Step-by-step explanation:

Given that:

Fuel efficiency of first car = 30 miles per gallon

Fuel efficiency of second car = 15 miles per gallon

Total distance traveled = 825 miles

Total gas consumption = 40 gallons

To find:

Number of gallons consumed by each car = ?

Solution:

Let the number of gallons consumed by first car = [tex]x[/tex] gallons

As per question statement, number of gallons consumed by second car:

[tex]40-x[/tex]

Number of miles covered by a car = Fuel efficiency [tex]\times[/tex] Number of gallons consumed

Number of miles covered by first car = 30 [tex]\times[/tex] [tex]x[/tex]

Number of miles covered by second car = 15 [tex]\times[/tex] ([tex]40-x[/tex])

Using the given statement:

[tex]30x+15(40-x)=825\\\Rightarrow 30x+600-15x=825\\\Rightarrow 15x=225\\\Rightarrow x =15\ gallons[/tex]

Therefore, Number of gallons consumed by first car = 15 gallons

Number of gallons consumed by second car = 40 - 15 = 25 gallons

Answer:

3/15 of a minute

Step-by-step explanation:

The graph of the function f and graph of the function g(x) have the different y-intercept but have the same end behavior option (C) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a graph of a function f and a function g(x) is:

[tex]\rm g(x) = (2)2^x[/tex]

If draw a graph of g(x) on the coordinate plane, it will be a exponential function.

For y intercept of g(x):

x = 0,

y = 2

But graph of a function f and graph of a function g(x) has same end behavior.

Thus, the graph of the function f and graph of the function g(x) have the different y-intercept but have the same end behavior option (C) is correct.

Answer:

$518

Step-by-step explanation:

The total gross payment = full-time payment + part-time payment

Given that:

She worked 46 hours for her full-time payment and time-and-a-half for anything and she is being paid $9 per hour;

and also worked for 7 hours for her part-time payment and she is being paid $11 per hour and time-and-a-half for anything

Then, the total gross payment = $46(9 1/2) + $7(11  1/2)

The total gross payment = $46(9.5) + $7(11.5)

The total gross payment = $437 + $80.5

The total gross payment = $517.5

The total gross payment ≅ $518
