7 0

Answer:

m=3

Step-by-step explanation:

Slope formula

m=\frac{y_2-y_1}{x_2-x_1}

Here

(x_1, y_1) = (-2, -1) \ \ and \ \ (x_2, y_2) = (-4, -7)

Slope can be calculated as

m=\frac{-7-(-1)}{-4-(-2)}

m= \frac{-6}{-2} \\m=3

podryga [215]

Answer:

Mike can stitch one shirt in 6 hours and in 1 hour he can stitch \frac{1}{6} (0.167) shirts.

Step-by-step explanation:

Mike can stitch 7 shirts in 42 hours

to calculate the time that he takes to make 1 shirt, we have to divide 42 by 7.

He can stitch 1 shirt in = \frac{42}{7} = 6 hours

Now we calculate the work done in one hour.

He can stitch in 1 hour = \frac{1}{6}  shirts or 0.167 shirts

Mike can stitch one shirt in 6 hours and in 1 hour he can stitch \frac{1}{6} shirts.

Dimas [21]

Answer:

The width of the rectangular room =x= 8

Step-by-step explanation:

Given: A rectangular room is twice as long as it is wide, and its perimeter is 48 meters.

To find: The width of the room.

Solution: Let the width of the rectangular room= x meters, then the length of the rectangular room will be = 2x.

Now, Perimeter of rectangular room=2(l+b)

⇒48=2(2x+x)

⇒24=3x

⇒x=8 meters

Then, the width of the rectangular room =x= 8 meters and the breadth of the rectangular room=2x=2(8)=16 meters.
