Answer:
45
Step-by-step explanation:
3z² - 6z
3(5)² - 6(5)
3(25) - 30
75 - 30
as x increases, y increases
C. 490.
25% = 0.25.
If the number of emails that Ryan and Taylor each received is x emails then Sara received 2x + 0.25 * 2x = 2.5 emails.
So 2x + 2.5x = 882
x = 882/4.5
x = 196.
So Sara received 2.5 * 196
= 490 emails.
b=-a
899.5
