Answer:
1.07
Step-by-step explanation:
because 13 divided by 13.91 is 1.07
Answer:
one solution
Step-by-step explanation:
y=-3x+5
y=1/2x-2
You can tell straight off the bat, it does have a solution, and it isn't infinite solutions. If it had no solution, it would have the same slope but different y-intercepts. If it had infinite solutions, the 2 equations would have to be the exact same. So there is only one solution.

Answer:

Step-by-step explanation:
A highway engineer wants to compute the change in elevation of a section of road. The horizontal distance of this section of road is 2km and downgrade is 8%
The slope formula is given by

m = 8% = 8/100
run = y = 2km

21 is the real answer
because of BODMAS
A= πr2
d=10m
2r=d
2r=10
r=5
A= π•5^2
A=3.14 •25
A=78.5 m^2
