The coordinates of r is ( 4, -1 )
80 - [50 - {20/2 - (16 - 2/2) ÷ 3}]
80 - [50 - {20/2 - (15) ÷ 3}]
80 - [50 - {10 - 5}]
80 - [50 - {5}]
80 - [45]

Answer:
4√7
Step-by-step explanation:
5√7 + √7 - 2√7
Taking out common term, √7.
= √7 ( 5 + 1 - 2)
Simplify the terms in the bracket.
= √7 (4)
= 4 √7
3/4+5/6 divided by 2/3 is 8/4 or 2
Do 5/6 divided by 2/3 first to get 5/4
then use 5/4 to +3/4 and the answer is 8/4 or 2
(2-c,y) is the answer for the problem.
