Step-by-step explanation:
Add the decimals first to get .84 then add the real numbers to get 46.
4/1 = 2/x...4 miles to 1 hr = 2 miles to x hrs
cross multiply because this is a proportion
(4)(x) = (1)(2)
4x = 2
x = 2/4 reduces to 1/2...so she can walk 2 miles in 1/2 hr (or 30 minutes)
Answer: Solve for
x

by simplifying both sides of the equation, then isolating the variable.

Step-by-step explanation:
If you toss a pair of dice
1,000 times, how many times would you expect to get a sum of 12 as the result. When
you toss a die there is 1/6 probility that you will get 6 so if you toss
another die the probability is the same. The get a sum of 12 the probability is
1/36.
So if you toss 1000 times,
<span>You will get about 1000
(1/36) = 27 times</span>
