Solve the following equation:
15(x-3)/5 = 3 (2x - 3)

x = ?

Answers

Answer:

x=0

if u wat step by step answer just tell me n ill do it

Answer:

0

Step-by-step explanation:

15(x-3) / 5  =  3(2x-3)

Distribute

(15x - 45) / 5  =  6x - 9

Multiply both sides by 5

15x - 45  =  (6x-9) x 5

Distribute

15x - 45  =  30x - 45

Gather the x's one side, and the other numbers on the other

-15x = 0

x = 0

A concert promoter charges $65 per ticket for a concert. The promoter's cost will be $5500 plus $4 per ticket.

If r = revenue and n = number of tickets sold, then r(n) shows how revenue (amount of money received from ticket sales) depends on the number of tickets sold.

r(n) = 65n

If c = cost and n = number of tickets sold, then c(n) shows how cost (expenses of the concert promoter) depends on the number of tickets sold.

c(n) = 4n + 5500

Answers

Answer:

here you go mate

you would just plug in the formulas given to you following the hint it's:

r(n) - c(n)

which goes to

65n - (4n + 5500)

then we can simplify that to  

61n - 5500

Part 2:

61(850) - 5500

51850 - 5500 = 46350

this means if he sells 850 tickets he will make a net of 46350 dollars

0.25D+0.10Q = 4.95D+Q=27

0.10D+0.25Q = 27D+Q=4.95

Answers

Answer:

Answer is F:
 y = 2x + 4

Step-by-step explanation:

The slope-intercept form of a line is given by
y = mx + b

where m is the slope of the line and b is the y-intercept ie the y value where the line crosses the y axis for x = 0

In the line y = 2x + 4, the slope of the line is 2

If 2 lines are parallel to each other, they must have the same slope

Therefore the line passing through (-1,2) must have an equation of the form y = 2x + b.

There are only 2 choices that fit this equation, F and H

If we substitute the values of x=-1  into the F equation for testing we get

y = 2(-1) + 4 = -2 +4 = 2 which is the correct value for y for the point(-1,2)

The other choice y = 2x + 3 does not work because substituting for x we get

y = 2(-1) + 3 = -2 + 3 = 1 which is not the value of y for the point (-1,2)

What is the equation for the line that passes through the coordinates (3, 4) and (5,8)?

Answers

Find slope:
(8-4)/(5-3) = 4/2 = 2
Y = 2x + b
4 = 2(3) + b, b = -2
Equation: y = 2x - 2

The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches, what is the length?
А. 12 inches
B. 15 inches
C. 21 inches
D.40 inches​

Answers

the answer would be B. 15 inches
Given :-

The perimeter of a rectangle is 42 inches. The width of the rectangle is 6 inches.

To Find :-

The length

Solution :-

We know that,

☆ Perimeter of a Rectangle = 2 (length + width)

Hence,

42 = 2 (length + 6)

or, 42/2 = length + 6

or, 21 = length + 6

or, length = 21 - 6

or, length = 15

The length is 15 inches.

Therefore, the correct answer is option (B) 15 inches.
