For this case we have the following variables:
x: number of free throws that Tessa made
y: total number of free throws
We now write the relationship of free throws.
We have then:

Simplifying the expression we have:


Answer:
The fraction of the free throws that she made is:

Answer: 1) 2x+18=-15
2) -33+18
Step-by-step explanation: 1) multiply the outer number by the numbers inside the parentheses : 2 times x would = 2 because x is not by itself so it would be X=1x and you are multiplying 2x1 which = 2 and add the variable x so it would be 2×, and same with 18, you multiply 9x2 which =18 and thats how i got 2x+18 doesnt matter if i havent found the x yet because we already know what it equals to which is -15... 2) X=16.5 so to check we do 2×-16.5 which = -33 and add 18 it = -15
(IM NOT SURE ABOUT THE THRID ONE )
Step-by-step explanation:
(4/3)–1 = 3/4 and (1/4)–1 = 4/1
now we have,
(3/4 - 4)–1 = (-13/4)–1
= -4/13
Answer:
