Solve for b.<br> 3-2(b-2)=2-7b3−2(b−2)=2−7b

lyudmila [28]

Step-by-step explanation:

3 - 2(b - 2) = 2 - 7b

To solve this first distribute -2 to (b - 2)

3 + (-2b + (-2) x -2) = 2 - 7b

when we simplify this it becomes:

3 + (-2b + 4) = 2 - 7b

We take (-2b + 4) out of the parenthesis:

3 - 2b + 4 = 2 - 7b

Now simplify again.

7 - 2b = 2 - 7b

Now send all the b's to one side and constants on the other.

7 - 2 = -7b +2b

5 = 5b

b = 1

Trava [24]

Answer:

Eli has to run for 2.25 minutes at this pace to win the bet.

Step-by-step explanation:

At his last track meet, Eli ran the 400-meter dash in 54 seconds.

So, the speed of Eli's run is $\frac{400}{54} \times 60 = 444.44$ meters per minute.

Now, if Eli is determined to run a whole kilometer with the same speed, then it will take Eli to run 1 kilometer within $\frac{1000}{444.44} = 2.25$ minutes.

Hence, Eli has to run for 2.25 minutes at this pace to win the bet. (Answer)
