Answer:
x = –4
Step-by-step explanation:
x = –koef x / (2•koef x²)
Answer:


Step-by-step explanation:
The given system is
3x-2y=6
0.4(20y+15)=x
The slope intercept form is y=mx+c.
For the first equation, 3x-2y=6, we add -3x to both side -2y=-3x+6

For 0.4(20y+15)=x, we expand to get:


Divide through by 8

Therefore the system in slope-intercept form is:


ANSWER

EXPLANATION
The given equation is

We add the additive inverse of 31 which is -31 to both sides of the equation to get,

Simplify;


Answer:
She can make 27 bags
2 pieces of candy is left over
Step-by-step explanation:
She has 245 Chocolate Twisters.
she puts 9 Chocolate Twisters in each treat bag,
1 bag hold 9 chocolates
9 chocolates = 1 bag
So 245 chocolates in how many bags
Divide 245 by 9
use long division
2 7 -----------> Quotient
------------------------------------
9 245
18 (subtract it)
-------------------------
65
63 (subtract it)
----------------------------
2 -----------> remainder
She can make 27 bags
2 pieces of candy is left over
