Which equation correctly rearranges the formula D=rt to find the time it will take her to run around the lake? A) t=d/r
B) t=r/d
C) t=d+r
D) t=d-r

t = D/r

Step-by-step explanation:

D = rt

Divide each side by r to isolate t

D/ r = rt/r

D /r = t

The time required is D/r

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
