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
Answer:
<h2>28 lollipops.</h2>
Step-by-step explanation:
Let's say that
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:

Where
is friend's lollipops, and
is Matt's lollipops.
Replacing values we have:

Therefore, in the bag were 28 lollipops in total.
1 over 7 to the 2nd power
Divide by rt on both sides

Subtract 2L from both sides

Subtract 9 then multiply by 4

Multiply by K
The general formula: y=mx+b
(6,2) ⇒ x=6,y=2
m=3
b=?
2=3*6+b
2=18+b
b=-16
<u>y=3m-16</u>
