shtirl [24]

Well that would be 105 - 10. If you spent 105 minutes in total and 10 of that was putting your stuff away, take that 10 minutes away and you’d get 95. So, she spent 95 minutes washing 3 cars in total. If you divide that 95 into 3s, you get rounded 31 minutes each.

In a rectangle, the length is five times the width.

8_murik_8 [283]

Answer:The perimeter =12w

Step-by-step explanation:

Let the width represent W and Length represent L

Length= 5 x width

L=5W

W=W

Since perimeter =2(L+w)

Substitute for L=5w

=2(5w+w)

=2(6w)

=12w

Choose the equation that represents the line that passes through the point (-1, 6) and has a slope of -3.

stich3 [128]

Answer:

Equation of line is $\mathbf{y=-3x+3}$

Option A is correct.

Step-by-step explanation:

We need to write an equation that represents the line that passes through the point (-1, 6) and has a slope of -3.

The equation will be of slope-intercept form: $y=mx+b$

where m is slope and b is y-intercept

We are given slope m =-3, we need to find y-intercept b

Finding y-intercept

using slope m=-3 and point (-1, 6)

$y=mx+b\\6=-3(-1)+b\\6=3+b\\b=6-3\\b=3$

So, y-intercept b is 3

Now the equation of line having slope m= -3 and y-intercept b = 3 is

$y=mx+b\\y=-3x+3$

Equation of line is $\mathbf{y=-3x+3}$

Option A is correct.
