Answer:

B) 2(y-3)=7+2y-3

Step-by-step explanation:

2(3y-1)=7-6y-2

6y-2=7-6y-2

6y-(-6y)-2=7-2

6y+6y-2=5

12y-2=5

12y=5+2

12y=7

y=7/12

-----------------------

2(y-3)=7+2y-3

2y-6=2y+4

2y-2y-6=4

0-6=4

-6=4

no solution

---------------------

2(3-2y)=7+4y-2

6-4y=4y+5

6-4y-4y=5

6-8y=5

8y=6-5

8y=1

y=1/8

----------------------

2(3y-2)=7-6y-2

6y-4=5-6y

6y-(-6y)-4=5

6y+6y=5+4

12y=9

y=9/12=3/4

The Candy Store held a raffle, and Matt won the grand prize. He won a gift card to the store, as well as a bag of giant lollipop

seropon [69]

Answer:

<h2>28 lollipops.</h2>

Step-by-step explanation:

Let's say that $n$ is the total number of lollipops in the bag, which Matt won.

So, if Matt gave 21 lollipops to his friends, and he kept with 7 lollipops, that means there were 28 lollipops in the bag.

If we represent this as an equation, would be:

$n=F+M$

Where $F$ is friend's lollipops, and $M$ is Matt's lollipops.

Replacing values we have:

$n=21+7=28$

Therefore, in the bag were 28 lollipops in total.

Divide by rt on both sides
$a) \: p = \frac{i}{rt}$
Subtract 2L from both sides
$b) \: m = 9 - 2l$
Subtract 9 then multiply by 4
$c) \: x = 4(2k - 9) = 8k - 36$ Multiply by K
$d) \: p = rk$

m=3
b=?

2=3*6+b
2=18+b
b=-16
