1) 2.7*10=27 (total number of miles ran by everyone)
4*3=12 (to find how many miles not averaged, multiply)
27-12=15 (how many miles left over for the other 6 people to run)
15/6= 2.5 (your answer)
2. 80/400= .2 (E)
3. Given:
x-5/4=-9/5
Mulitply everything by 4 to cancle it out
x-5=-36/5
add 5 to both sides
x=-11/5
4. A

Answer:
a proportion
Step-by-step explanation:
If you know one ratio in a proportion, you can use that information to find values in the other equivalent ratio.
Answer:
11. Slope of the line is 7/10.
12. Slope of the line is
Step-by-step explanation:
11. Given points are:
(-6, 1) and (4, 8)
Slope of a line is given by the formula;
m =
m =
m =
m =
Slope of the line is 7/10.
12. Given points are:
(2, -3) and (5, -4)
Slope of the equation is;
m =
m =
m =
Hence,
Slope of the line is .
A polygon that has 4 sides and two sets of parallel sides is a parallelogram. In a parallelogram, each set of opposite sides is congruent, but all four sides do not have to be congruent.
