-5x + y = 1
- 10x + 2y = -2
plz answer right this is the last math problem i have to do!

-1 -y/5

Step-by-step explanation:

-5x + y = 1

Subtract yy from both sides.

-5x=1-y

−5x=1−y

2 Divide both sides by -5−5.

x=-\frac{1-y}{5}

x=−

5

1−y

-10x+2y=-2

Factor out the common term 22.

2(5x+y)=-2

2(5x+y)=−2

2 Divide both sides by 22.

5x+y=-1

5x+y=−1

3 Subtract yy from both sides.

5x=-1-y

5x=−1−y

4 Divide both sides by 55.

x=\frac{-1-y}{5}

x=

5

−1−y

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
