The value of r so the line that passes through (-5,2) and (3,r) has a slope of -1/2 is -2
<u>Solution:</u>
Given that line is passing through point (-5, 2) and (3, r)
Slope of the line is 
Need to determine value of r.
Slope of a line passing through point
is given by following formula:
--- eqn 1

On substituting the given value in (1) we get

Hence the value of "r" is -2

Answer: 12.5%
Step-by-step explanation:
So we can do 11.5/92 with x/100 cross multiply with 100 and 11.5,
11.5 x 100 = 1150
Next we divide 1150 by 92,
1150/92 = 12.5
Therefore we get 11.5/92 = 12.5/100!
Answer: C. 7.5%
Solve as decimal
0.5*0.15=0.075
Move two decimal points over
0.075 -> 7.5
Change back to percent
7.5%
Volume equals mass divided by density.
