Answer/Step-by-step explanation:
An equation that describes the relationship can be written as 
.
Using the two sets of coordinates, (2, 140) and (4, 280), calculate the slope (m) as shown below:
Substitute m = 70 into
The equation would be:
This equation can be interpreted as follows:
The heart's resting rate is 70 beats each minute.
10 divided by 2= 5 Each person will get 5 punch
Answer
-1(3a-2)
Step-by-step explanation:
A. 3 times 10^4
90000000 divided by 3000 is 30000 which happens to be equal to 3 times 10^4
If you want to learn how to do this just take your whole number ex: 3 and put 10^6 and you will have 3 followed by 6 zeros. The ^ is just how many zeros will follow your whole number at first.
2x = 18
--------------------
x = 18 : 2 =
x = 9
-------------------
(2*9 : 3) + 1 = 7
6 + 1 = 7
