Answer: D, 6km/hr.
Step-by-step explanation:
Heather can finish a 12-kilometer race in 2 hours, and now we have to find how many kilometers she can ride/run at in 1 hour.
How many hours can Heather run in 1 hour? To solve that, we can use the equation 12 ÷ 2.
12 ÷ 2 = 6.
Therefore, if Heather keeps her pace constant, then her rate will be 6km/hr, or D.
The answer is C. Supplementary.
Answer:
6
Step-by-step explanation:
Let the 4 people be A, B, C and D. If each of them shakes hands with another person exactly one time then that means
A shakes with B, C and D. So 3 handshakes
B already shakes with A. So B shakes with C and D. 2 handshakes
C already shakes with A and B. So C shakes with D only. 1 handshake.
D already shake hand with all above.
Total handshakes: 3 + 2 + 1 = 6
Question is not complete, so i have attached it.
Answer:
B: -2x² - 6x² - 6x + 3x + 3 + 2
Step-by-step explanation:
From the image attached, the given polynomial is;
3 - 6x - 2x² + 3x - 6x² + 2
For like terms to be next to each other, we have to rearrange it as follows;
-2x² - 6x² - 6x + 3x + 3 + 2
Like terms are x² and x, thus they are now arranged next to each other.
The only option that corresponds to our answer is option B
