The total number of marbles is 30+20+50= 100, so. Since there are 20 red marbles and 50 blue marbles. There are 30+50=80. 80/100=4/5= 80%
A. you plug in to a calculator, which will give 1840.986 so you need to round up to 1840.99. if you truncate it to .98 then he won't reach 2000 in 3 years
b. for this one if you look at the equation given to find the principle it is principle = result (1+rate) ^ -time
if you re arrange this you get result=principle (1+rate)^time
so result = 1840.99(1.028)^5
= 2113.57

Answer:
1. x = 10 - y/2 2. x = 2 + 5y/6
Step-by-step explanation:
