You've already completed the first step by lining up terms with the same variables. Like addition, simply add them together column by column. x+(-x) equals 0 so it is cancelled out. 4y plus 6y is 10y. 9+11=20. We are left with 10y equals 20, so y equals 2. Then plug in the y value into either equation. I will use the first so x +4(2)=9. x must equal 1. Double check by plugging in both x and y into the second equation.
Answer:
164 people
Step-by-step explanation:
100% represents the 150 people who attended last year.
this year , there is an increase of 9% , which will make the total percentage to be 109%.
if ; 100% = 150 people
109% = ?
cross multiply to get 163.5 the round off to get 164
Answer: I'd assume its B 100 miles each day.
Step-by-step explanation:
Because 70 x 100 is 7,000 which is equal to the amount of miles stared in the question
If the problem youre solving as the value of the x and y you can make those linear equations, however u can make them with only the x val
