If y = x/k where k is a constant, and y = 5 when x = 30, what is the value of y when x = 60?
Alex777 [14]

Answer:

\huge\boxed{\sf y = 10}

Step-by-step explanation:

<u>Given Equation is:</u>

y = x / k

We know that y = 5 when x = 30

Put it in the above equation

5 = 30 / k

k = 30 / 5

k = 6

<u>Now,</u>

y = ? when x = 60

Put it in the above equation

y = x / k

y = 60 / 6

y = 10

\rule[225]{225}{2}

Hope this helped!

How many solutions does the equation have?<br> -2(v - 2) = -3 - 2v
Mashcka [7]

Answer:

no solution

Step-by-step explanation:

- 2(v - 2) = - 3 - 2v ← distribute left side

- 2v + 4 = - 3 - 2v ( subtract 4 from both sides )

- 2v = - 7 - 2v ( add 2v to both sides )

0 = - 7 ← not possible

Hope this helps
