Last year at a certain high school, there were 50 boys on the honor roll and 100 girls
Sedbober [7]

there were 145 boys on the honor role and 60 girls equally given a total number of 205. This year, the number of boys decreased by 20% = 0.2*145=29

145-29=116

116 is this year number of boys on honor role

For girls.

=0.25*60=15

60-15=45

45 is this year number of girls on honor role.

Total number of students on honor role this year is 116+45 =161

Percentage of decrease = 1 -(161/205)*100% =( 1-0.785)*100

= 0.215*100

= 21.5%

Step-by-step explanation:

<u>Step 1: Define</u>

<u />\displaystyle \frac{6}{19} = \frac{x - 12}{2x - 2}<u />

<u />

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

  1. Cross-multiply:                     \displaystyle 6(2x - 2) = 19(x - 12)
  2. Distribute:                             \displaystyle 12x - 12 = 19x - 228
  3. Isolate <em>x</em> terms:                     \displaystyle -12 = 7x - 228
  4. Isolate <em>x</em> term:                      \displaystyle 216 = 7x
  5. Isolate <em>x</em>:                               \displaystyle \frac{216}{7} = x
  6. Rewrite:                                \displaystyle x = \frac{216}{7}
