Jack has [ 1 (x+3) ].
Angus has [ 5 (x+3) ].
Together they have [ 6 (x+3) ].
That's all we can tell from the information given.
The total could be
3 + 15 = 18
4 + 20 = 24
5 + 25 = 30
6 + 30 = 36
7 + 35 = 42
etc.

What is relative frequency?
Relative frequency is the proportion of all given values in an interval, i.e., the frequency of the event/value divided by the total number of data points.In other words...If you picked 12 marbles out of a bag, and 9 of them were green, the frequency of green marbles would be 9... but the relative frequency would be that number (the frequency) divided by the total number of marbles... so the relative frequency would be 9/12 or 3/4.--Relative frequency is the time that you get something successfully over the total number of times attempted... for example.. you flipped a coin 10 times, and you got heads 4 times. the relative frequency would be 4 over 10.
A bag contains 3 red marbles 5 blue marbles 8 yellow marbles and 4 black marbles what is the theoretical probability of randomly picking each color marble?
The theoretical probability of randomly picking each color marble is the number of color marbles you have for each color, divided by the total number of marbles. For example, the probability of selecting a red marble is 3/20.
What is the probability of choosing a red marble from a jar containing 5 red 6 green and 4 blue marbles?
First, you add all the numbers together- 5+6+4=15. So the number of red marbles (5) and the total number of marbles (15)= 5/15=1/3
A bowl contains a total of 26 blue and red marbles There are two more red marbles than blue marbles How many blue marbles are in the bowl?
There are 26 total marbles. We will call x the number of blue marbles. So there are x+2 red marbles. If you add them together you get x + x + 2....and all that equals 26 (subtract 2 from each side and add the two x's together) 26 - 2 = x + x 24 = 2x then divide each side by two and you get 24/2 = 2x/2 simplified is 12 = x So x is 12 (blue marbles) and x + 2 is 14 is (the amount of red marbles). 12 + 14 = 26!
David and Joseph have a total of 328 marbles. Matthew and David have 176 marbles. Joseph has 5 times as many marbles as Matthew. How many marbles does David have?
D+J = 328 M+D = 176 J = 5M D+5M = 328 D+M = 176 subtract 4M = 152 M = 38 D = 176-38 = 138
The number of marbles in jar A is 4 times than in jar B If 96 marbles are transfred from jar A to jar B will become 4 times than in Jar A Find the total number of marbles in both jars?
They started off with A = 128, B = 32.
Zachary has ninety marbles five-ninths of them are blue how many of the marbles are blue?
Number of marbles in total = 90 Fraction of marbles are blue = five-ninth Number of blue marbles = five-ninth of ninety = 50 So, the answer is 50 blue marbles.
Jerry has a total of 23 marbles The marbles are either blue or green He has three more blue marbles than green marbles How many green marbles?
Let X = the number of green marbles. X+3 = the number of blue marbles. X + (X+3) = 23 2X + 3 = 23 2X = 20 X = 10 or the number of green marbles.
What is the probability of selecting 4 red or 5blue marbles?
The probability of selecting 4 red marbles or 5 blue marbles depends on how many marbles there are altogether, and how many of the total number of marbles are red and how many are blue.

What does ratio mean in a math problem?
it means a number verses another number, like a fraction Here;s an example you have 10 white marbles, 3 blue marbles, and 7 green marbles. what is the ratio of green marbles to the total amount of marbles? hat you do is look at the green marbles, and in this case, there are 7. Now add up all the marbles, which is 20. Your ratio is then 7:20.
What is the probability of drawing two pink marbles if the first one is placed back in the bag before the second draw?
it depends on the total number of marbles you have!
How do you do a multiply?
I'm not sure how they teach multiplying today, but when I was in school, it began with memorizing. We had to memorize the 'times tables' that had all of the numbers from zero to ten times all of the other numbers from zero to ten. Once you could name any of those from memory, we learned how to lay out a formula to multiply larger numbers, first by zero to ten, then by any larger number. The letter X was used as the symbol to tell you to multiply the numbers. When you start learning, we laid the problem out like this: You and two of your friends each have eleven marbles; how many marbles in total for the three of you: 11 marbles x3 friends 33 total marbles Or if each of you has twelve marbles: 12 marbles x3 friends 36 total marbles Once you've memorized the 'times tables' and learned to do this simple form of multiplying, you can ask how to multiply larger numbers. You will find a times table with some helpful hints on the link below.
What is the equation used to determine probability?
Number of possibilities for one category / Total of all possibilities. For example, if I had a bag of marbles where there are three white marbles and two black marbles. The probability of pulling out a white marble is how many white marbles are in the bag which is: three. But the total of things you can draw out of the bag can either be one of the three white marbles or one of the two black marbles. 3 white marbles+ 2 Black marbles= five marbles. Possibility is 3/5 for drawing a white marble.
A bag contains 3 red marbles 5 blue marbles 8 yellow marbles and 4 black marbles what is the theoretical probability of randomly picking each color marble?
The theoretical probability of randomly picking each color marble is the number of color marbles you have for each color, divided by the total number of marbles. For example, the probability of selecting a red marble is 3/20.
Boddy has a bag full of marbles that he keep in his room he has 35 red marbles and 25 green marblesfind the ratito of red marbles and put it in its simplest form?
Ratio is a fraction. Number of total marbles is the denominator, number of red marbles is numerator. So the fraction is 35/60. This can be reduced by dividing by 5/5, so the simplest form is 7/12.
Jerry has a total of 23 marbles the marbles are either blue or green he has three more blue marbles than green marbles how many marbles does he have?
He will have 13 blue marbles and 10 green marbles.
