Answer:
Step-by-step explanation:
okay so to get 10% of 20 you just move the decimal to the right one so 25.0 would become 2.5 then to find 20% of that you multiply by 2 so 2.5 x 2 = 5 so that means the team lost 5 girls. 25-5=20 therefor there are 20 players on the team this year
Answer:
20
Step-by-step explanation:
Answer:
y=2.5x+5 or f(x)=2.5x+5
Step-by-step explanation:
We know 2 given points. (-2, 0) and (0,5)
With these two points we can calculate the slope:
0-5/-2-0+
-5/-2=
5/2 = 2.5
Because the y-intercept is given at 5, we can put these numbers into y=mx+b and get y=2.5x+5 or f(x)=2.5x+5
4n-5=3n+2
subtract 3n from each side
4n -5 -3n = 3n +2 -3n
n -5 = 2
add 5 to each side
n-5+5 = 2+5
n = 7
To solve a equation with a variable, you need to get the variable alone. I got the variable on the left hand side and the constants on the right hand side
