-32-y=90
-y=90+32
-y=122
y=-122
So, the answer is y=-122

Answer: y=-61/2

Step-by-step explanation: - 4(8 + y)/-4 = 90/-4

8+y-8=-45/2-8

-8(2)-45/2

-16-45

-61

y=-61/2

Write an equation of the line that passes through the point (5, -8) with slope 5

Oxana [17]

$\Large\texttt{Answer}$

$equation=$ $\bold{y=5x-33}$

$\overline{\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad}$

$\Large\texttt{Process}$

⇨ Use the formula below

$\bf{y-\hfill\stackrel{y \:co-ordinate}{y1}=\hfill\stackrel{slope}{m}(x-\hfill\stackrel{x\:co-ordinate}{x1)}}$

⇨ Substitute the parameters:

$\bold{y-(-8)=5(x-5)}$

$\bold{y+8=5x-25}$

$\bold{y=5x-33}$

Yvonne had a rope that measured 2/5 long. She

yawa3891 [41]

Answer:

Number of smaller ropes she can make from the larger rope = 2/3

Step-by-step explanation:

Total length of rope = 2/5 ft

Length of smaller rope = 3/5 ft

How many smaller ropes can she make from the larger rope?

Number of smaller ropes she can make from the larger rope = Total length of rope / Length of smaller rope

= 2/5 ÷ 3/5

= 2/5 × 5/3

= (2*5)/(5*3)

= 10/15

= 2/3

Number of smaller ropes she can make from the larger rope = 2/3

andre rode his bike at a constant speed he rode 1 mile in 5 minutes which of these equations represents the amount of time in mi

Alex777 [14]

We are given

Andre rode his bike at a constant speed he rode 1 mile in 5 minutes

Firstly, we will find constant speed

In 5 minutes , distance travelled =1 miles

so, we get speed

$v=\frac{1}{5} mile/min$

Let's assume T is time in minutes

D is the distance in miles

we know that

$Time=\frac{Distance}{speed}$

so, we can plug value

and we get

$T=\frac{D}{\frac{1}{5} }$

so, we get

$T=5D$ ...............Answer
