Carlos find the absolute value of -5 3/10 and then find is the opposite of his answer Jason finds the opposite of -5 3/10 and th
a_sh-v [17]

we know that

5 \frac{3}{10}= \frac{5*10+3}{10} = \frac{53}{10}

Step 1

<u>Carlos's method</u>

1) <u>Find the absolute value of -\frac{53}{10}</u>

\left|-\frac{53}{10}\right|=\frac{53}{10}

2) <u>Find the opposite</u>

opposite=-\frac{53}{10}

Step 2

<u>Jason's method</u>

1) <u>Find the opposite of  -\frac{53}{10}</u>

opposite=\frac{53}{10}

2) <u>Find the absolute value </u>

\left|\frac{53}{10}\right|=\frac{53}{10}

Step 3

<u>Compare the answers</u>

\frac{53}{10} > -\frac{53}{10}

therefore

<u>The answer is</u>

The greater value is obtained with the method of Jason

<u>Algebra I</u>

  • Terms/Coefficients
  • 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.
