Tamika went hiking with her friends. the beginning of -1 feet. the highest elevation on hiking path is 100 feet. what is the difference in the two elevations?

hello!

so the difference is 101 and here is why!

you want to minus -1 from 100

100 - (-1)

but because it is a double negative it will become addition

100 + 1

so the difference is 101 feet

i hope this helped :)

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
