Answer: 1.29n + 0.79w + 3.39b  is the expression.

The total cost is $12.91

Step-by-step explanation:  Substitute the number of pounds for each given supply. Multiply to get the individual amounts, then add all of those amounts to find the total cost.

1.29(2) + 0.79(4) + 2.39(3) = total

2.58 + 3.16 + 7.17 = 12.91

Step-by-step explanation:

<u>Step 1: Define Equation</u>

2t + 5 = 2t + 5

<u>Step 2: Solve for </u><em><u>t</u></em>

  1. Subtract 5 on both sides:                    2t = 2t
  2. Divide 2 on both sides:                        t = t

Here we see that <em>t</em> does indeed equal <em>t</em>.

∴ t = infinite amount of solutions

What the answer to k in -14=k+6​
lapo4ka [179]

Answer:

14=k+6

We move all terms to the left:

14-(k+6)=0

We get rid of parentheses

-k-6+14=0

We add all the numbers together, and all the variables

-1k+8=0

We move all terms containing k to the left, all other terms to the right

-k=-8

k=-8/-1

k=+8
