Answer:
Joseph caught 7 tadpoles
Step-by-step explanation:
Let the number of tadpoles caught by Joseph be x
The number of tadpoles Wendy caught will be ;
9(x + 3)
After Joseph was upset, he released half of Wendy’s tadpole and then six times as many as Joseph caught swam away leaving Wendy with only three tadpoles left;
Hence, mathematically;
9(x + 3)/2 - 6x = 3
Multiply through be 2
9(x + 3) - 12x = 6
9x + 27 -12x = 6
9x -12x = 6-27
3x = 21
x = 21/3
x = 7
Answer:
Step-by-step explanation:
Let's take it part by part.
" lina is 1 year less than..." So this means a value that we get some other way -1. So let's call it x-1 for now. The next part tells us how to get x.
"3 times his age" so now we have 3y-1, where y is Adam's age. We know adam's age though.
3*2 - 1
6-1
5
Basically, follow the order of operations, Multiplication comes before adding and subtracting.
So, do 4636 x 968, and 325 x 5 first.
Then subtract 23 from 4636 x 968, and add the result to the product of 325 x 5
It should be 4489250
Answer:
100 minimum
Step-by-step explanation:
because 100 times 12 equals 1200
Answer:
1/160
Step-by-step explanation:
Assuming that you want to roll a 5 and then select the ace of hearts that would make this a sequence of events. In order to find the probability of this happening, you would need to multiply the probability of each of these events happening separately with one another.
Since there are a total of 6 possible outcomes when rolling a die (1,2,3,4,5,6) which rolling a 5 is only one of the options. Meaning that the probability of rolling a 5 is 1/5.
In a deck of cards, there are a total of 32 cards in the deck and only 1 of those cards is an ace of hearts. Meaning that the probability of getting the ace of hearts is 1/32. Now we simply multiply these two probabilities together to get the probability of the sequence.
1/5 * 1/32 = 1/160
