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.
It has a coefficient of 4 :)
Answer:
1st one
Step-by-step explanation:
C.64 and octagon has 8 sides and one side is 8cm so you multiply 8x8
Hi!
Given:

Multiply both sides by 

<em>Notice the sign was flipped. This is because when you multiply or divide by a negative number, you must always flip the sign!</em>
<u>Now, for the graph:</u>

For < or > signs, it should be an open circle. For
or
signs, it should be closed.
Since
is less than 6, it should go to the left. Since it's a < symbol, it should be open. Therefore your answer is B.
(looks like you were right!!)
