Hey mate!
You stuck?
It shows the expression of the sum of the total miles per hour the car traveled.
Hope this helps! :)
2/27 total play both.
2/27 = .074 move the decimal over 2 places = 7% chance
Answer:
when you have two fractions that equal each other you want to solve by using cross multiply
What cross multiply is, is when you multiply diagonally so:
8/x=14/7
you would take 14*x and 8*7
14x=56 (you would then divide each side by 14)
x=4 (14/14=1, 56/14=4)
8/4=14/7
To check your work you could simplify
8/4=2
14/7=2
2=2, which is true
x=4
Hope this helps ;)
(100-9^2)/3
PEMDAS: parenthesis, exponents, multiply, divide, add, subtract
Lets' work on the parethesis first.
100-9^2
We can do the exponent first, 9^2=81, so 100-81=19
Then we divide and 19/3 is your final answer.
He has come from the hole in the roof because the text states that he did not come from a door, a window, or a chimney, and that is the only answer that was left.
