Probability = (number of possible successes) / (number of total possibilities).
<u>Number of total possibilities:</u>
Each cube can come up in 6 different ways.
Total number of possibilities = 6 x 6 = 36
<u>Possible successes:</u>
There are 2 different ways to roll a 3 . . .
1 . . . 2
or
2 . . . 1
The probability is 3/36 = 1/12 = 0.0833... = (8 and 1/3) percent
Equation:
distance + distance = 2250 miles
3x + 3(x-110) = 2250
6x - 330 = 2250
6x = 2580
x = 430 mph (rate of the westbound plane)
x-110 = 320 mph (rate of the eastbound plane)
PLS MARK BRAINLIEST!!!
Apples = $.30
Peaches = $.60
You can get this by setting up a system of equations that looks like this.
2x + 3y = 1.65
3x + 2y = 1.60
Where x is the amount of apples and y is the number of peaches. Then you can solve using any of the methods (I would suggest elimination for ease).
