The solution to linear equality is an interval denoted with k\in I.

Lets start solving.

We have

4k+k > k + 16

Simplify the inequality

4k > 16\Longrightarrow k > 4

If k > 4 then I=(4,\infty) or simply k\in(4,\infty).

Hope this helps.

A cashier collects 124 bills totaling $920 dollars. Assuming that the cashier collects $5, $10, and $20 bills, and that she coll
musickatia [10]
Let the no. of $10 bills be x, the no. of $5 bills be 2x, and the no. of $20 bills be y.

<span>A cashier collects 124 bills => x + 2x + y = 124  => 3x +y =124

</span>totaling $920 dollars => ($10)(x) + ($5)(2x) + ($20)(y) = $920 => 20x + 20y = 920

Now you got 2 equations :
3x +y =124 &
20x + 20y = 920

3x +y =124 => y=124-3x
Then Sub y=124-3x into 20x + 20y = 920,
ie. 20x + 20(124-3x) = 920 
     20x + 2480 - 60x = 920
     2480 - 40x = 920
      2480 - 920 = 40x
               1560 = 40x
                      x = 39

How to solve 10-3(3x-40)=-9x
vichka [17]
<span>Simplifying 10 + -3(3x + -40) = -9x
 
Reorder the terms: 10 + -3(-40 + 3x) = -9x
10 + (-40 * -3 + 3x * -3) = -9x
10 + (120 + -9x) = -9x
 
Combine like terms: 10 + 120 = 130 130 + -9x = -9x
 
Add '9x' to each side of the equation. 130 + -9x + 9x = -9x + 9x
 
Combine like terms: -9x + 9x = 0 130 + 0 = -9x + 9x 130 = -9x + 9x

Combine like terms: -9x + 9x = 0 130 = 0
 
Solving 130 = 0
 Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.</span>
