Two​ trains, Train A and Train​ B, weigh a total of 379 tons. Train A is heavier than Train B. The difference of their weights is 255 tons. What is the weight of each​ train?

Answers

Answer 1

Answer: A = 317

B = 61

Step-by-step explanation:

The following equation can be gotten from the question given. This will be:

A + B = 379 ........ i

A - B = 255 ........ ii

From equation i, make A the subject of the formula

A = 379 - B ...... iii

Put the value of A in iii into equation ii

A - B = 255

(379 - B) - B = 255

379 - B - B = 255

379 - 2B = 255

2B = 379-255

2B = 124

B = 124/2

B = 62 tons

Since A + B = 379

A + 62 = 379

A = 379 - 62

A = 317 tons

Answers

Answer:

Step-by-step explanation:

90(5/6)

450/6

75

9514 1404 393

Answer:

  75

Step-by-step explanation:

90 = 6 × 15

There are 15 6-day periods in 90 days. The gardener will have mowed ...

  15 × 5 = 75

times in those 15 periods.

He will mow 75 times in a 90-day period.

__

If you like, you can set up a proportion for the unknown number of mowings (m).

  mows/days = m/90 = 5/6

Multiply by 90 to solve for m.

  m = 90(5/6) = (90/6)(5) = 15(5) = 75 . . . . . . this should look like the above

the answer is none the right answer would be x>= -37/3
All you have to do is put in one of the numbers given and put it in the inequality as x. For example, in the picture you can see that I put in each of the numbers as x for the equations and checked which ones came out as false or true. The ones that came out as true are the correct answer. So the answer is 8 and 2.

the width if a rectangular room is 1 less than twice the length if the perimeter is 196 feet how long is the length

Answers

Answer:

l = 33 feet

Step-by-step explanation:

Let length be l.

Width, b = 2l-1

Perimeter of the room, P = 196

We know that the perimeter of the rectangle is given by :

P = 2(l+b)

196=2(l+2l-1)

98=3l-1

Adding 1 both sides.

98+1=3l-1+1

3l=99

l = 33 feet

So, the length of the room is 33 feet.

The future value of the account is given by the formula ...

  A = P(1 +r/12)^(12t) . . . . principal P invested at rate r for t years

Solving for t, we find ...

  A/P = (1 +r/12)^(12t) . . . . . . . . . . . divide by P

  log(A/P) = 12t·log(1 +r/12) . . . . . . take logs

Divide by the coefficient of t, then fill in the numbers.

  t = log(A/P)/(12·log(1 +r/12)) = log(202800/93000)/(12·log(1 +.068/12))

  t ≈ 11.497

3x + 50 = 6x - 10

Solve by combining like-terms and isolating x. Move the 3x to the right by subtracting it from both sides.

50 = 3x - 10

Move the 10 to the left by adding it to both sides.

60 = 3x

Divide the 3 from both sides to isolate the x.

x = 20

Furthermore, this can be checked by plugging in 20 to x and seeing if the expression is true.

3(20) + 50 = 6(20) - 10

The computation of the number of second would be

In the case when the ball would hit the ground, the ball height would be zero

So the following equation would be
