Brianna made cookies. She used 5/8 of a cup of flour and 1/2 of a cup of sugar. How much more flour than sugar did Brianna use?
KiRa [710]

Answer:

She used 1/8 or 12.5% more flour than sugar

Step-by-step explanation:

flour: 5/8

sugar: 1/2 = 4/8

\frac{5}{8} - \frac{4}{8} = \frac{1} {8}  = 0.125

0.125 = 12.5%

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

3m - n = -10

2m + n = -5

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

<em>Elimination</em>

  1. Combine equations:                    5m = -15
  2. Divide 5 on both sides:               m = -3

<u>Step 3: Solve for </u><em><u>n</u></em>

  1. Define equation:                    3m - n = -10
  2. Substitute in <em>m</em>:                      3(-3) - n = -10
  3. Multiply:                                  -9 - n = -10
  4. Add 9 to both sides:              -n = -1
  5. Divide -1 on both sides:         n = 1

Consider the equation. Which graph shows a line that is perpendicular to the line defined by the given equation? A. In a linear
mixer [17]

The graph second represents the line that is perpendicular to the line y = 4x - 2 option  (B) is correct.

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

\rm m =\dfrac{y_2-y_1}{x_2-x_1}

The question is incomplete:

The complete question is:

Consider the equation y = 4x - 2 Which graph shows a line that is perpendicular to the line defined by the given equation?

Please refer to the attached picture.

The given line:

y = 4x - 2

The slope of the line m = 4

The slope of the line which is perpendicular to the above line:

M = -1/4 = -0.25

The graph second has a slope of -0.25

\rm y\ -2\ =\ \dfrac{\left(2-0.5\right)}{-4-2}\left(x+4\right)

y - 2 = -0.25x - 1

y = -0.25x + 1

Thus, the graph second represents the line that is perpendicular to the line y = 4x - 2 option  (B) is correct.
