Answer:

(4x + 1) + (5x + 4) + E = 180.

Simplify: Combine the x values

4x + 5x = 9x.

Now add 4 + 1 = 5.

So far we have; 9x + 5 + E = 180.

180 - 5 = 175.

9x = 175

175/9 = 19.4 repeated. X = 19.4 repeated.

Substitute in the value we have so far.

(4 x 19.4 repeated + 1) + (5 X 19.4 repeated + 4) = 180

So, E must be 0 for this equation to work.

Answer:

The unit rate is accurately $\frac{1}{4}$ (km/minute)

Step-by-step explanation:

(1,1/4) means that the vehicle traveled 1/4 km within 1 minute.

The unit rate for this problem is also known as the speed of the vehicle.

So to find the speed, you need to use distance over time.

---> Unit rate: $\frac{1}{4}\\$ / 1 = $\frac{1}{4}$ (km/minute)

(2,1/2) means that the vehicle traveled 1/2 km within 2 minutes.

Same process:

---> Unit rate: $\frac{1}{2}$ / 2 =

Because of this, the unit rate is accurately $\frac{1}{4}$ (km/minute)
