Luda [366]

Answer:

n=16

Step-by-step explanation:

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

12−2(n−1)=−18

Step 1: Simplify both sides of the equation.

12−2(n−1)=−18

12+(−2)(n)+(−2)(−1)=−18(Distribute)

12+−2n+2=−18

(−2n)+(12+2)=−18(Combine Like Terms)

−2n+14=−18

−2n+14=−18

Step 2: Subtract 14 from both sides.

−2n+14−14=−18−14

−2n=−32

Step 3: Divide both sides by -2.

−2n /−2  =  −32 /−2

n=16

kirill115 [55]

Answer: 1 / 5 of the total distance.

Step-by-step explanation:

They traveled 7/10 of the distance on Saturday. This means that on Saturday, the fraction left was:

= 1 - 7/10

= 3/10 of the distance

On Sunday, they traveled 2/3 of this remaining distance. The fraction of the distance traveled is therefore:

= 2/3 * 3/10

= 6 / 30

= 1 / 5 of the total distance.
