A because 1-10 would be -9 and she was a meter above so positive but they descended 10 meters no negitve
Answer:
Is there an image?
Step-by-step explanation:
First of all, you add 1/3 and 4/5, so you get:

To add 2 fractions, they need to have the same denominator. Since 3 and 5 don't have a common factor, so you multiply 1/3 by 5, and 4/5 by 3, so you get:


Now, the two fractions got the same denominator, and you can add them by adding the numerators over the same denominator. (You don't add denominators in addition) so you get:


That's the sum of 1/3 + 4/5.
Now, they want the sum of the 2 fractions 7 times. So you multiply 17/15 by 7. And as you know, 7 = 7/1. So you get:

In multiplication no need to have the same denominator. You multiply nominators by nominators and denominators by denominators. So you get:


Since 119 and 15 don't have a common factor, so they can't be simplified.
So, the answer is 119/15.
Hope this Helps! :D

Answer: The answer should be 38.
I also saw that you placed a t after the -2 so I wasn't sure if it was a mistake or if it was on purpose or you left another t out of the problem on accident.
Step-by-step explanation:
2.3 (14+6) -2 to the power of three
2.3 (20) -2 to the power of three
2.3 (20) -8
46-8
38
I really hoped this helped and if I got it wrong with the t just reply to me c:
