The cost for an order of 100 kilograms of steel bars is $230. The cost for an order of 150 kilograms of steel bars is $320. Write an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x). Show or explain how you found your equation.

Answers

Answer:

y = 9x/5 + 50

Step-by-step explanation:

We are represent the information as coordinate (x,y)

If the cost for an order of 100 kilograms of steel bars is $230, this is expressed as (100, 230)

Also if the cost for an order of 150 kilograms of steel bars is $320, this is expressed as;

(150, 320)

Find the equation of a line passing through the points. The standard form of the equation is expressed as y = mx+c

m is the slope

c is the intercept

Get the slope;

m = y2-y1/x2-x1

m = 320-230/150-100

m = 90/50

m = 9/5

Get the y-intercept by substituting m = 9/5 and any point say (100, 230) into the expression y = mx+c

230 = 9/5(100)+c

230 = 9(20)+c

230 = 180 + c

c = 230-180

c = 50

Get the required equation

y = mx+c

y = 9/5 x + 50

Hence an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x) is y = 9x/5 + 50

a college spends 40% of an individual's tuition on salaries and the remainder on other costs if they spend 1,800 on other costs how much is an individual's tuition?​

Answers

Answer:

$3000

Step-by-step explanation:

If the remainder is spent on other costs, then that means 60% of the tuition as spent on other costs.

To find the total tuition, divide 1800 by 0.6:

1800/0.6

= 3000

So, their tuition was $3000

Daniel can spend no more than $40 at the fair. If admission into the fair is $10 and the rides cost $1.50 each, which inequality represents the greatest number of rides Daniel can go on?


A. 10r + 1.50 ≥ 40
B. 1.50r + 10 ≤ 40
C. 1.50r + 10 <40
D 10r+1.50<40

Explain your reasoning and solve the inequality :

Answers

Answer:

B

Step-by-step explanation:

The sum spent has to be either equal to or less than 40. So r many rides, each of them being 1.50, plus 10 dollars has to equal to less or equal to 40 dollars.

Answer:

The answer is B

The greatest number of rides Daniel can go on is 20.

Step-by-step explanation:

Total: The same or less than 40

Fair Admission: 10

ride: 1.50x

40 ≤ 10 + 1.5r

To solve:

40 ≤ 10 + 1.5r

40 - 10 ≤ 10 + 1.5r - 10

30 ≤ 1.5r

30 ÷ 1.5 ≤ 1.5r ÷ 1.5

20 ≤ r

The greatest number of rides Daniel can go on is 20.

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

What is the value of y in the solution to the system of equations?

One-thirdx + One-fourthy = 1

2x – 3y = –30

Answers

Answer:

y-value = 8

Step-by-step explanation:

1/3x + 1/4y = 1 is the same as 4/12x + 3/12y = 1

which is the same as (4x + 3y)/12 = 1

which is the same as 4x + 3y = 12

add both equations and the 'y' will cancel and you will have 6x = -18

x = -3

2(-3) - 3y = -30

-6 - 3y = -30

-3y = -24

y = 8
