The equation that matches the given situation is 
. So, after two moves, Eric's elevation changed 
meters above.
We know that in mathematics, subtraction means removing something from a group or a number of things. What is left in the group gets smaller when we subtract. The minuend is the first element we use. The subtrahend is the part that is being removed. The difference is the portion that remains after subtraction.
Assume that "negative" means climbing down and "positive" means climbing up. We must locate the elevation change in this area.
Given that Eric climbed straight down 
meters. So we can write 
.
Again Eric climbed straight up 
meters. So, we can write .
Then the change = 
=
=
=
=
=
=
=
Therefore, the equation that matches the given situation is . So, after two moves, Eric's elevation changed meters above.

Mike biked 10 miles in 1.5 hours. Mila bikes at the same rate too.
Therefore, she will bike x miles in 3.5 hours
(10/1.5) = (x/3.5)
You cross multiply
1.5x = 10 x 3.5
1.5x = 35
x = 35/1.5
x = 23 miles (approximately)
I hope this helps
Answer:
y=0.5x + 5
Step-by-step explanation:
The points are (0,5) and (-10,0)
to find the slope do
0-5/-10-0 = 5/10 = 1/2 = 0.5
next plug one of the points into point slope formula
y-y1=m(x-x1)
lets use the point (-10,0)
y1=0
x1= -10
m= 0.5
y-0=0.5(x- -10)
y = 0.5(x+10)
distribute the 0.5
y=0.5x+5
Answer:
There are multiple possibilities. One is there are 12 boys, and 16 girls. 12+16= 28 which is between 20 and 30. That would be 12:16, which can be simplified to 3:4. There is also 9 boys, and 12 girls. that would be 9:12, which can be simplified to 3:4. Also, 9 + 12 = 21, which is between 20 and 30.
The ratio of shots made to shots took is 6:10
