Marcus can drive his boat 36 miles down the river in 3 hours but takes 4 hours to return upstream. Find the rate of the boat
in still water and the rate of the current.

Answers

Answer:

With river 12 miles per hour

Against river 9 miles per hour

wv = water velocity vsw = boat velocity in still water

vsw +wv = 12 mph

vsw -wv = 9 mph

2 * vsw = 21 mph

boat velocity in still water = 10.5

Since vsw + wv = 12 then

water velocity = 1.5 mph

Step-by-step explanation:

Answer:

speed in still water: 10.5 Current: 1.5

determine the slope of the linear graph y=12x+7

Answers

Answer:

12x

Step-by-step explanation:

3x-2y=1x+4y=33 elimination process

Answers

Answer:

x = 5 ; y = 7

Step-by-step explanation:

3x - 2y = 1 --------------------(I)

x + 4y = 33 ------------(II)

Multiply equation (II) by (-3) and then add. So, x will be eliminated and we can find the value of y

(I) 3x - 2y = 1

(II)*(-3) -3x -12y = -99 {Now add}

- 14y = -98

y = -98/14

y = 7

Plugin y = 7 in equation (I)

3x - 2*7 = 1

3x - 14 = 1

3x = 1 + 14

3x = 15

x = 15/3

x = 5

A rectangular mat has an area of 7/12 in2. The length of the mat is 5/6 in. What is the width of the mat

Answers

The width of the mat with the given area and length is 7/10 in.

What is the width of the mat?

The area of a rectangle is expressed as;

A = l × w

Where l is length and w is width.

Given the data in the question;

Area A = 7/12 in²Length l = 5/6 inWidth w = ?

We plug our given values into the above equation and solve for w.

A = l × w

7/12 = 5/6 × w

w = 7/12 ÷ 5/6

w = 7/12 ÷ 6/5

w = 42/60

w = 7/10 in

Therefore, the width of the mat with the given area and length is 7/10 in.

only 1 and 2. input the numbers for x

Answer:

1 and 2

Step-by-step explanation:

If x is 1: 2 x 1 + 7 = 2 + 7

= 9 This works.

If x is 2: 2 x 2 + 7 = 4 + 7

= 11 This works

If x is 3: 2 x 3 + 7 = 6 + 7

= 13 This does not work since 2x + 7 has to be less than 13.
