svlad2 [7]

The blank spaces in the task content can be filled with; Substitution property, 90° and subtraction property.

<h3>What are the missing statements in the proof?</h3>

Since it follows from the vertical angles theorem that angle 1 = angle 4 as they are congruent.

Additionally, angles 1 and 2 are said to be complementary and hence, the sum of their measures is equal to 90°.

Finally, by virtue of the subtraction property of equality, the measure of angle 2 is; 90° - 40° = 50°.

I need help on number 18
vladimir2022 [97]

Answer:

Plan C

Step-by-step explanation:

Complete the table first:

To find the number of weeks for each amount of $ to save, divide $500 by the amount.

Plan B: $500/$30 = 16.7 weeks, rounded to 17 weeks

Plan C: $500/$40 = 12.5 weeks, rounded to 13 weeks

Plan D: $500/$50 = 10 weeks

Save $500 in less than 16 weeks with $20 extra:

Which plans need less than 16 weeks?

Plans C and D.

Check the amount of money Plan C gives:

In 13 weeks, how much extra money does this plan give?

Extra money = Total - $500

The total money is 13 weeks * $40 = $520

$520 - $500 = $20 in extra money

Therefore Plan C gives Todd $500 in less than 16 weeks, with $20 extra.
