The cost to rent a construction crane is $750 per day plus $250 per hour of use. What is the maximum number of hours the crane can be used each day if the rental cost is not exceed $2500 per day ? Write amd solve the inequality

Answers

Answer 1

Answer: Let's use x to represent the number of hours since we don't know that.

750+250x<2500
Subtract 750 from both sides.
250x<1750
Divide both sides by 250.
x<7
The most hours that they can do is 7, or it can be less.

Answer 2

Answer:

Answer:

x = 7

Step-by-step explanation:

x= number of hours

"cost is not exceed $2500 per day"

not exceed = less than

750+250x < 2500

250x< 2500-750

250x < 1750

x < 1750/250

x<7

7 hours

PLEASE HELP ASAP!!!!Hugo is writing a coordinate proof to show that the midpoints of a quadrilateral are the vertices of a parallelogram. He starts by assigning coordinates to the vertices of quadrilateral RSTV and labeling the midpoints of the sides of the quadrilateral as A, B, C, and D. Quadrilateral R S T V in a coordinate plane with vertex R at 0 comma 0, vertex S in the first quadrant at 2 a comma 2b, vertex T also in the first quadrant at 2 c comma 2 d, and vertex V on the positive side of the x-axis at 2 c comma 0. Point A is between points R and S, point B is between points S and T, point C is between points T and V, and point D is between points R and V. Enter the answers, in simplified form, in the boxes to complete the proof. The coordinates of point A are ( , ). The coordinates of point B are ( , ). The coordinates of point C are (2c, d) .

What are scale drawings? can you give an example?

Answers

Scale Drawings are drawings that are used to show the true size of something.
Scale drawings are most commonly used in maps, or in large scale drawings. These show the scale of something. It may show that 1cm is equivalent to 1km, which would allow someone to measure the map to see how far the distance it. It also allows a map to be made smaller, and less detailed- making it often easier to read.
Hope this helps :)

The total amount y (in dollars) in your savings account after buying x video games is represented by y=90-10x. You have $40 in your account after buying video games. How many video games did you buy?

Answers

5 video games bought.

Explanation:
Step one) identify all variables.
> y = money in bank acc AFTER buying (x) video games.
Step two) y = $40
Step three) substitute
> 40 = 90 - 10x.
Step Four) solve for x
> subtract 90 both sides.
-50 = -10x
DIVIDE by -10 on both sides ( to isolated x)
This equals 5 = x
x is number of video games bought meaning >> 5 video games bought :))

Final answer:

The equation y = 90 - 10x indicates the amount left in the savings account after buying x number of video games. Plugging in 40 for y and solving for x, it is found that 5 video games were purchased.

Explanation:

To find out the number of video games purchased, you need to solve the equation y = 90 - 10x for 'x' when 'y' is 40. This equation represents the total amount in your savings account (y) after buying x number of video games.

Plug in 40 for 'y' in the equation:
40 = 90 - 10x
Subtract 90 from both sides of the equation:
-50 = -10x
Divide both sides by -10:
5 = x

So, you bought 5 video games to have $40 left in your savings account.
