-8a/8 = 22
8 divided by 22 is 2.75
a = -2.75
Answer:
x = 47/7 or 6.714
Step-by-step explanation:
7 (x+3) = 72-4
7x + 21 = 68
7x = 68 - 21
7x = 47
x = 47/7 or 6.714
Answer:
85 points
Step-by-step explanation:
Let :
Total points made by team = x
Points made by the player :
2/5 of total = 2x/5
1/3 of the rest :
Points left = x - 2x/5= 3x /5
1/3 of 3x /5
1/3 * 3x / 5
= 3x / 15 = x / 5
Points made by rest of the players = 34 points
Hence, total points scored, x :
x = 34 + 2x /5 + x /5
x = 34 + 3x / 5
x - 3x/5 = 34
2x / 5 = 34
2x = 34 * 5
2x = 170
x = 170 / 2
x = 85
Total points scored by team = 85
Welcome to the concept of the maths.
Here, we can see, that Linear equation always have highest power or degree of its variable as '1' ,
thus here, y = 3/x has degree as -1 and y = x^2 +5 has degree 2 ,
hence,
The equations that are NOT linear are
2.) y = 3/x and 5.) y = x^2 + 5
Let's think that The NUMBER is x so it would be 2x+13=27 so this goes to 2x=27-13 which is 2x=14 so x equal to 7
