Hello!

The probability of something is just the amount of the object to the total amount of objects

So the answer is \frac{2}{5} which is also 40%

Hope this helps!

x = -15

Step-by-step explanation:

x =  \frac{2}{3} x - 5

Collect like terms and simplify

x -  \frac{2}{3} x =  - 5 \\  \frac{1}{3} x =  - 5

Cross multiply

x =  - 5 \times 3 \\  \\ x =  - 15

Which one is the better option and why need at least four sentences explaining which option is better please someone help
SCORPION-xisa [38]

9514 1404 393

Answer:

  Option B

Step-by-step explanation:

The cost of 6 turkeys at $1 per pound will be between $78 and $90. The cost of 6 turkeys at $20 each, B2G1, will be $80. We imagine that the average weight of turkeys in the 13-15 lb range will usually exceed 13 1/3 pounds, the weight at which the cost per pound is the same. That means, 6 turkeys at $1 per pound will likely cost more than $80, unless extreme effort is made to choose only the lightest turkeys.

Option B is likely to be cheaper; certainly so, if heavier turkeys are preferred.
