Arnoldo needs to write this system in slope-intercept form. Which shows how he could do that?
Jobisdone [24]

Answer:

y =  \frac{3}{2}x - 3

y =  \frac{1}{8} x -  \frac{7}{8}

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

y =  \frac{3}{2}x - 3

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

8y  + 7 = x

8y= x - 7

Divide through by 8

y =  \frac{1}{8}x -  \frac{7}{8}

Therefore the system in slope-intercept form is:

y =  \frac{3}{2}x - 3

y =  \frac{1}{8}x -  \frac{7}{8}

Use inverse operations and properties of equality to isolate the variable m+31=307
otez555 [7]

ANSWER

m = 276

EXPLANATION

The given equation is

m + 31 = 307

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

m + 31   +  - 31= 307 +  - 31

Simplify;

m +0= 307 - 31

m = 276

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
