Collins is working.......
lesya [120]
Let n represent the amount Colin earned on Sunday.

On Sat. he earned n/2; on Sun. he earned n; and on Friday he earned (1/2)(n/2).

Then n/2  +  n  + n/4 = $70

Mult. all terms by 4 to eliminate fractions:

2n + 4n + n = $280

7n = $280  =>  n = $40

Colin earned n/2, or $20, on Saturday; n, or $40, on Sunday; and n/4, or $10, on Friday.

Note that $20 and $40 and $10 add up to $70, as they must.

Solve for w<br><br> Simplify as much as possible <br><br> 3(3w-5)=12<br><br> plz help ty ;)
Masteriza [31]

Step-by-step explanation:

Simplifying

3(3w + -5) = 12

Reorder the terms:

3(-5 + 3w) = 12

(-5 * 3 + 3w * 3) = 12

(-15 + 9w) = 12

Solving

-15 + 9w = 12

Solving for variable 'w'.

Move all terms containing w to the left, all other terms to the right.

Add '15' to each side of the equation.

-15 + 15 + 9w = 12 + 15

Combine like terms: -15 + 15 = 0

0 + 9w = 12 + 15

9w = 12 + 15

Combine like terms: 12 + 15 = 27

9w = 27

Divide each side by '9'.

w = 3

Simplifying

w = 3
