What does y equal y-16-3y=0

Afina-wow [57]

Answer:

y = - 8

Step-by-step explanation:

y - 16 - 3y = 0

Group like terms

y - 3y - 16 = 0

Add similar elements: y - 3y = - 2y

- 2y - 16 = 0

Add 16 to both sides

- 2y - 16 + 16 = 0 + 16

Simplify

- 2y = 16

Divide both sides by - 2

$\frac{-2y}{-2}$ = $\frac{16}{-2}$

Simplify $\frac{-2y}{-2}$ : y

$\frac{-2y}{-2}$

Apply the fraction rule: $\frac{-a}{-b} = \frac{a}{b}$

= $\frac{2y}{2}$

Divide the numbers: $\frac{2}{2} = 1$

= y

Simplify $\frac{16}{-2}$ : - 8

$\frac{16}{-2}$

Apply the fraction rule: $\frac{-a}{-b} = \frac{a}{b}$

$-\frac{16}{2}$

Divide the numbers: $\frac{16}{2}$ = 8

= - 8

y = - 8

Patty can make 10 purses in 8 hours. At this rate how many purses can she make in 28 hours

Norma-Jean [14]

8 x 3 = 24
24 + 4 = 28
Now if 10 purses are made in 8 hours, and we can see we timesed 8, 3 times, thats 10 x 3 = 30
Now we take in to count the last 4 hours
30 + 4 = 34
And 4 is half of 8 so if we cut 10 in half we get 5.
So, the answer is 35
At least that's what I got :)

The price of a cell phone call costs $4.35 for 3 minutes. How much would a 20-minute call cost?

It would equal 29$ dollars because you divide 20 and 3, and with that answer you multiply by 4.35 :)
