Two sides of a triangle measure 10cm and 18cm . Which could be the measure of the third side of the triangle?

1 answer:

8 0

It cannot be 30, because the sum of two sides should be more than third side
-not D
10+18=28 <30

it cannot be 6 +10 < 18

it cannot 8
8+10=18

so it is has to be C) 12
12+18>10
10+12>18
10+18>12
answer C. 12 cm

<h3>The answer is:</h3><h2>D. 5 hours</h2><h2 />

The equation should be:

(70x) - (20x) = 250

Because we have all the possible answers, we can plug one of them into x to see if it equals 250 miles.

Use an educated guess. I'm going to go with 5 because it seems reasonable.

(70 * 5) - (20 * 5) = 250

Let's check to see if it equals 250:

70 * 5 = 350

20 * 5 = 100

350 - 100 = 250

Therefore, the answer is D. 5 hours.
