There are 100 bolts and 2 wingnuts in each bookcase kit. What is the unit rate in bolts per wingnut?
gayaneshka [121]
Since they are asking for the unit rate in bolts per wing nut, you can think of it as bolts per ONE wing nut. 

To figure that out, you can divide 100 bolts by 2 wing nuts to get 50 bolts per wing nut.

  • Coordinates (x, y)
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

y = -2x + 4

2x + y = 4

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

<em>Substitution</em>

  1. Substitute in <em>y</em>:                                                                                                  2x + (-2x + 4) = 4
  2. Combine like terms:                                                                                         4 = 4

Here we see that 4 does indeed equal 4.

∴ the systems of equations has an infinite amount of solutions.
