Dimas is playing a game that uses a number cube. The sides of the cube are labeled from 1 to 6. Dimas wants to roll a 2 or 3. He
wlad13 [49]

Answer:

B. 1/3

Step-by-step explanation:

The total number of sides in the cube are 6 (1,2,3,4,5,6). If Dimas only wants to roll either a 2 or 3 then that would mean that he has 2 chances out of the total 6 probable outcomes to roll one of those numbers. Therefore, in order to find the probability of this happening in a single roll we need to divide the number of times that his two choices appear on the dice by the total number of sides the dice has, like so...

2 / 6 = x

If we simplify it would give us \frac{1}{3}

Solve 8/t+5 = t-3/t+5 + 1/3
Aleks04 [339]

\frac{8}{t}  + 5 = t -  \frac{3}{t}  + 5 +  \frac{1}{3}  \\  \\ 1. \:  \frac{8}{t} =  -  \frac{3}{t} +  \frac{1}{3}   \\  \\ 2. \: 24 = 3t^{2}  - 9 + t \\  \\ 3. \: 24 - 3t^{2} + 9 - t = 0 \\  \\ 4. \: 33 - 3t ^{2}- t = 0 \\  \\ 5. \: t =  \frac{1 +  \sqrt{397} }{ - 6}  \:  \frac{1 -  \sqrt{397} }{ - 6}  \\  \\ 6. \: t =  -  \frac{1 +  \sqrt{397} }{6}  \:  -  \frac{1 -  \sqrt{397} }{6}

Dale drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 7 hours. When Dale drove h
matrenka [14]
If you let X = the distance in miles from Dales's house, and understand rate = distance/ time, the rate going to mountains = x/7, and back from mountains is x/5. If dale was 18mph fast going home, the equation would be...
(coming home rate) = (going to mountain rate) + 18 which is
x/5 = x/7 + 18. Then solve for X.
Use the least common denominator = 35 so multiply everything by 35 and you get...

7x = 5x+630
simplify...
2x = 630, then
x = 315 .
Dale live 315 miles away from the mountains.
