You are considering hiring a DJ for a birthday party. The price of the DJ is $35 per hour. All customers must
pay a $75 set up fee. The fixed cost is added to the total bill.

Write an equation to determine the total bill, t, for a customer. Use h to represent the number of hours the DJ works.


t = 75h + 35

t = 35 + 75

t = 35h + 75

h = 35t + 75

Answers

Answer:

The answer is C

Step-by-step explanation:

t = bill for the customer

h= number of hours Dj worked

1) t = 75h + 35

This is wrong because h represents the number of hours the Dj worked. 75 is how much the customers paid as a setup fee.

2) t = 35 + 75

This is wrong because it's asking you to use "h" and "t" to determine the total. This is just a regular equation.

3) t = 35h + 75

This is right because as it says in the problem "The price of the Dj is $35 per hour" It also says use "h" to represent the number of hours the DJ works.

The "t" is used for the customer bill and 75 represents the setup fee

4) h = 35t + 75

This is wrong because h respresents how many hours the DJ works.

"t" represents the bill for the customer. The "t" would be in the beginning of the equation and the "h" would be behind the amount the DJ got paid per hour.

The sum of 2 numbers is 54. Their difference is 116. What are the numbers?

Answers

Answer:

Step-by-step explanation:

first, let the numbers be x and y.

so by question we have,

x+y=54.......(I)

x-y=116......(I I)

now, solve it through elimination method,

x+y=54

x-y=116

here, y and y cancelled out and we get,

or, x+x=54+116

or, 2x=170

or, x=170/2

therefore, x=85

now put value of x in any equation. let's put in eqn (I), we get,

or, x+y=54

or,85+y=54

or, y=54-85

so, y= -31

therefore, the numbers are 85 and - 31.

y = 6/5x - 1

hope this helps :) !!

Answer:

[tex]y = \frac{6}{5}x - 1[/tex]

Step-by-step explanation:

use the formula

[tex]y = mx + b[/tex]

m is the slope and b is the y-intercept. Begin with b, where the line crosses the y-axis (vertical axis). It crosses at -1, so this is b.

Next move with m. Do rise/run. Start at the y-intercept and you are going to rise 6 and run 5 to the next point. So the slope is 6/5. Leave as an improper fraction. Plug-in for m. Since the line goes uphill from left to right it has a positive slope.

find the y intercept
y = 3/4x - 4

Answers

It is 8+783 to the 2 power
the y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b). It is also the value of y when x = 0.

To find the y-intercept, set x = 0:

y = -3/4(0) - 4

y = 0 - 4

y = -4.

Therefore, the y-intercept is (0, -4), or -4.

find the value of each variable 2x+4x+108

Answers

Answer:

Step-by-step explanation:

2x + 4x + 180

We have to do combine like terms.

2x and 4x are like terms, so add 2x to 4x. Which gives you 6x. Now you have the expres 6x + 180. You can’t find the variable for this expression, its unsolvable. If you meant, “2x + 4x = 180” Then yes, it would be solvable.

All you would have to do Is, 2x + 4x which gives you 6x, and now divide both side by 6. 6x divided by 6, the two 6 would cancel out, and 180 divide by 6, leaving you with 30. So x should equal to 30.

3/4 divided by 3/16

3/4 times 16/3

4

Answer: 4

Step-by-step explanation: do the brackets first. which is (1/2 * 3/8) to multiply these two together multiply numerator by numerator and denominator by denominator. Or, top * top / bottom * bottom

so we'd do 1*2 / 3*8. so it would give you 3/16.

now all we have left to do is divide 3/4 by 3/16.

to do this you can multiply by the reciprocal of the second value(3/16 will become 16/3)

now we have [tex]\frac{3}{4}[/tex] * [tex]\frac{16}{3}[/tex]  you can cancel out each 3 to give you 1/4 * 16/1

and you can also divide both 16 and 4 by 4 (16/4=4)

this gives you a final equation of 1 * 4 for a final answer of 4

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Let x represent the number of​ 30-day periods until the value of the gift cards will be equal.

Tavon has a gift card for $90 that loses $4 for each​ 30-day period it is not used. This means that x 30-day periods, the amount left would be

90 - 4x

He has another gift card for $ 80 that loses $3.50 for each​ 30-day period it is not used. This means that x 30-day periods, the amount left would be

80 - 3.5x

For the amounts left on each card to be the same, the number of periods would be

90 - 4x = 80 - 3.5x

90 - 80 = - 3.5x + 4x

10 = 0.5x

x = 10/0.5

x = 20

The value of each card when they have equal​ value is

90 - 4 × 20 = 90 - 80

= $10

Therefore, It will take twenty 30-day periods until the value of the gift cards will be equal. The value of each card when they have equal​ value is $10

Step-by-step explanation:

The equation of the line is y = ( 4/3 )x + 2.

What is an equation of a line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

Given that the equation is parallel the line y = ( 4 / 3 )x + 8 and passes through the point ( -6 , -6 ).

The general equation of the line is

y = mx + c

The slope of the required line will be the same as the slope of the line parallel to the required line.

m = ( 4 / 3 )

The equation of the line will be written:-

y = mx + c

y = ( 4 / 3 )x + c

-6 = ( 4 / 3 ) x -6 + c

c = 2

y = ( 4/3 )x + 2

Therefore, the equation of the line is y = ( 4/3 )x + 2.
