10. What is the measure of ZP?* E (15m + 17)º -Q (4m – 10) P (7m - 9)

vovikov84 [41]

Answer:

m∡P = 40°

Step-by-step explanation:

15m + 17 + 4m - 10 + 7m - 9 = 180

26m - 2 = 180

26m = 182

m = 7

∡P = 7(7) - 9 = 49 - 9 = 40

I really need help! Please, please, PLEASE do not give me a link.

Answer:

7 fiction and 23 non- fiction

Step-by-step explanation:

The number of non-fiction read was 5 less than 4 times the number of fiction books.

Assume fiction books are x.

An equation representing this would be:

x + (4x - 5) = 30

5x - 5 = 30

5x = 30 + 5

x = 35 / 5

x = 7 fiction books

Non-fiction books:

= 4x - 5

= 4 * 7 - 5

= 23 non - fiction books

Answer:

Step-by-step explanation:

Instead of dividing both sides by 5, it is multiplied

5x + 3 = 6 {Subtract 3 from both sides}

5x + 3 - 3 = 6-3

5x = 3 {Divide both sides by 5}

5x/5 = 3/5

x = 3/5
