Y= -2x+3 is the correct equation for this graph
19
Starting amount 5
Adding 6 and 8
5+6+8=19
To solve these, I like to write it out in expanded form for each rectangle.
Starting from left to right:
(12*7)+(12*5)+(12*7)+(7*5)+(12*5)+(7*5)
It can also be written as:
2(12*7)+2(12*5)+2(7*5)
This equals 358cm^2
It is squared because it is a result of multiplying 2 dimensions: length*width.
The gcf for 13 and 65 is 13 because that is the greatest number that 13 and 65 can divide into and for the 2nd question it is 13(1+5) bc you put the 13x1 equal 13 and 13x5 equals 65 so ya.
Answer:
3.019 hours.
Step-by-step explanation:
In this case they ask us to calculate the time in hours that are in those distances, for this we have the speed and the distance, we know that speed is equal to:
v = d / t
therefore the time would be:
t = d / t
we must pass the distance that is in kilometers to miles, like this:
350 km * 1 mile / 1.61 km = 217.4 mi
Now if replacing:
t = 217.4 / 72 = 3.019
Therefore, the time would be 3.019 hours.
