Answer:
<u><em>-29/15</em></u>
Step-by-step explanation:
- <u><em>Multiply 2 and 3 to get 6</em></u>
- <u><em>-6+2/3 + 11/15</em></u>
- <u><em>Add 6 and 2 to get 8</em></u>
- <u><em>-8/3+11/15</em></u>
- <u><em>LCM of 3 and 15 is 15. Convert -8/3 and 11/15 to fractions with 15 as the denominator</em></u>
- <u><em>-40/15 + 11/15</em></u>
- <u><em>Since -40/15 and 11/15 have the same denominator, add them by adding the numerators</em></u>
- <u><em>-40+11 / 15</em></u>
- <u><em>Add -40 snd 11 to get -29</em></u>
- <u><em>-29/15</em></u>

Answer:
5 mph.
Step-by-step explanation:
Let the runner travel at x miles an hour , then the cyclist travels at 5/ 3 * x
= 5/3 x miles an hour.
So we have the equation
5/3 x - x = 2 ( since the cyclist was travelling at 2 mph faster).,
2/3 x = 2
x = 3/2 * 2 = 3 mph.
So the cyclists speed was 3 * 5/3
= 5 mph.
Answer:
98.5 cm2
Step-by-step explanation:
1/2 × b × h = A
1/2 × b × 10 = 100
5b = 100
b = 100/5
b = 20
