You are part of a rowing team. Every 1, miles you stop to take a drink of water. How many times will you stop to drink water if you row 10.2 miles?

10 stops I think as the 0.2 is not a full mile so you dont stop

Step-by-step explanation:

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
