Answer:

22

Step-by-step explanation:

We can use the order of operations (PEMDAS), to solve this equation.

We must first multiply and divide, and order. This means we divide 12 by 3 and get 4, then multiply that by 2 and get 8. (30-12÷3×2,30-4×2,30-8). Now we just subtract 8 from 30 and get 22 as our answer.

400 passengers go on a coach trip.
Afina-wow [57]

Answer: <u>₹759407.56</u>

Step-by-step explanation: Total No. of passengers = 400

1 Coach = 50 passengers

∴Total No. of coaches= 400/50=8 coaches.

Cost for each passenger= £23

∴Total cost for 400 passengers= 400x£23

= £9200 ( 1£=82.5443 ₹) ∴ Total cost for passengers = <u>₹759407.56</u>

Money spent per mile= 70p

∴Money spent for 200 miles= 200x70p=14000p

(1₹=100p) thus, 14000p=<u>₹140</u>

<u><em>Total profit</em></u>= <em>Money from the passengers- Money spent for fuel</em>

∴<u>₹759407.56- ₹140=  ₹7,59,407.56</u>

The owner of a malt shop spent $3 buying 2 boxes of cups with each box containing 516 cups. If he expected the cups to last 6 mo
beks73 [17]
172, since he bought two boxes and each had 516 there was 1,032 in all. Since he wants them to last 6 months, then you divide by six and get 172 :) I think this is what it is asking.

The length of a rectangle is 1 more than 3 times the width . If the perimeter of the rectangle is 18 units , what’s it’s area?
nika2105 [10]

Answer:

14 square units

Step-by-step explanation:

You need to know the formulas for the perimeter of a rectangle and the area of a rectangle, which are

2L + 2W - P     where L is the length, W is the width, and P is the perimeter

and

A = LW      

So we need to find the length and width to find the area


Step 1:  Write equations out of the given information

"The length of a rectangle is 1 more than 3 times the width" can be rewritten as

L = 3W + 1


"the perimeter of the rectangle is 18 units" can be rewritten as

2L + 2W = 18


Step 2:  Plug the first formula into the second one and solve

      2(3W + 1) + 2W = 18

Simplify...

      6W + 2 + 2W = 18

Combine like terms and subtract 2 from both sides

     8W = 16

Divide both sides by 8 to isolate the W

   W = 2


Step 3:  

Plug W = 2 into the formula for L and solve for L

  L = 3(2) + 1

      L = 6 + 1

        L = 7


Step 4:  Use the length and width to calculate the area

A = LW

  A = (7)(2)

     A = 14 units squared
