Answer:
11x-14xy
Step-by-step explanation:
3(2x- 3xy) + 5x-5xy
=6x-9xy+5x-5xy
=11x-14xy
9 1/2 * 15.15 = $143.925 dollar
Answer:
1. 2x + 8y = 10xy
2. 13ab + 15ab = 28ab
Step-by-step explanation:
This is because for question 2 the "a" and "b" stay together since it's on 13 and 15. So that is why you would get 28ab. For question 1 it's basicly the same but instead, you combine the two to get your answer.
Hope this helps.
To find how many degrees Celsius, divide your number in Fahrenheit by 5/9 (or approximately 0.56), then subtract 32. As an example we'll convert 90 degrees Fahrenheit into Celsius.
C = 5/9f - 32
C = 5/9 x 90 -32
C = 50.4 -32
C = 18.4
