Answer:
x = 8, y = 3
Step-by-step explanation:
Equating corresponding x and y coordinates , then
- y = - x + 5 ( multiply through by - 1 )
y = x - 5 → (1)
2x - 5y = 1 → (2)
Substitute y = x - 5 into (2)
2x - 5(x - 5) = 1 ← distribute and simplify left side
2x - 5x + 25 = 1
- 3x + 25 = 1 ( subtract 25 from both sides )
- 3x = - 24 ( divide both sides by - 3 )
x = 8
Substitute x = 8 into (1) for corresponding value of y
y = 8 - 5 = 3
Step-by-step explanation:
Mean =sum of values /number of values
total sum ↪️ 6+4+9+6+7+10+7
number of values is 7
= 49/7

Answer:
Maybe you can have someone read it to you to see if you can answer it that way after you answer it on your own a cupple of times
Step-by-step explanation:
No, because if he runs 7/30 mile each day he will run 210 miles each week because he is running 30 miles every day so he has to run 7/4.28 miles each day of the week to get 30 miles each week.
Answer:
n <=6.5
Step-by-step explanation:
Six less than two times a number is no more than 7
2n-6 <=7
Add 6 to each side
2n-6+6 <=7+6
2n <=13
Divide by 2
2n/2 <=13/2
n <=6.5
