  • AC is congruent to itself
  • AC bisects angle BAD, so that angles BAC and DAC are congruent
  • Both angles B and D are right angles, so they are congruent

This means triangles BAC and DAC are a pair of angle-angle-side triangles, so they are congruent to one another. Corresponding parts of congruent triangles are congruent, so the line segments BC and DC are congruent and have the same length.

Then

8n+2=2n+20\implies6n=18\implies n=3

Pete estimates that he has spent $64.50 on supplies for his lawn mower. He charges $12 per lawn for his service. Write a linear
nadya68 [22]

Answer:

The equation representing the Amount of profit Peter earns is y=12x-64.5 .

Step-by-step explanation:

Given:

Money spent on supplies = $64.50

Per lawn charge for mowing lawn = $12

Solution:

Let the amount of profit Pete earns be represented by 'y'.

Let the number of lawns to be mowed be represented by 'x'

Now we can say that:

Amount of profit Pete earns is equal to Per lawn charge for mowing lawn multiplied by number of lawns to be mowed minus Money spent on supplies.

framing in equation form we get;

y=12x-64.5

Hence The equation representing the Amount of profit Peter earns is  y=12x-64.5 .
