__. ___
30. 100
66 times 30 gets u 1980
then divide that by 100 and that gets you
19.8
that's how u do it for 1-4
except change the numbers

Answer:
y= -11/7x+8
move variables to the right hand side and change its sign
-7y=-56+11x
change the signs on both sides of the equation
7y=56-11x
divide both sides by 7
y=8-11/7 x
reorder the terms and get y= -11/7x+8
Answer: 19
Step-by-step explanation:
So, for this problem, you want to find the value of x. When you take a look at m(3), there is a 3 in the place of x, which means the x = 3. Then when you plug 3 into the equation, you get:
(4-3)2 + 15 + 2=
1(2) + 15 +2 =
2 + 15 + 2=
17 + 2=
