Answer:

Step-by-step explanation:

Begin by isolating the term with the r in it. Do that by subtracting 8.9 from both sides:

9.5r = -110.445 - 8.9 and

9.5r = -119.345 Divide both sides by 9.5 to get

r = -119.345/9.5 and

r = 12.56263158 (or you could leave it as a fraction)

The answer is 11.51.

8.9+9.5r=-100.445, so we have to remove the 8.9 by subtracting it from both sides.

9.5r=-109.345, but now we have to get r by itself, so we have to divide both sides by 9.5

r=-11.51

A spaceship is traveling at a steady rate. The table shows the distance the spaceship travels in a given period of time. Find th

nika2105 [10]

The distance of the spaceship in discuss as in the task content given can be evaluated as; 800miles.

<h3>What is the distance the spaceship travels in 4 minutes?</h3>

The distance travelled by the spaceship in discuss can be evaluated by means of the slope of the linear relationship as follows;

Hence it follows from ratios that by observation, the linear relationship has a slope of 200mi/min.

Consequently, we can evaluate the distance travelled after 4 minutes as;

Distance = 200 × 4 = 800mi.

Ultimately, the distance travelled per minute by the spaceship is; 800mi.

Remarks:

600 miles

520 miles

800 miles

1,080 miles
