Answer:
[See Below]
Step-by-step explanation:
Look at the "Fraction" column, all the fractions in this column must add up to 1 (because the whole bag contains only Red, Green, Blue or Other coloured beads).
So we work out the sum of missing fractions:
And so we know the fractions in the missing boxes must add up to .
This means that the number of blue and green beads is 2/3rds of the total number of beads in the bag. There are 12+4=16 blue+green beads so
.
So if there are 24 beads in the bag, then the red beads are 1/12th of 24 which is 2 and the other beads are 1/4 of 24 which is 6.
Finally to complete the missing fractions: there are 12 blue beads and 24 in total so the fraction of blue beads is 12/24 = 1/2. Similarly, there are 4 green beads so the fraction of green beads is 4/24 = 1/6.
(I thought this was a very tricky question. Let me know in the comments if something doesn't make sense, or if you need more explanation on any part, or even if you spot an easier way to do it that I can't.)

Answer:</h2>
In this exercise we have the following pattern:
1, -12, 12, -1
So we need to find the rule for this patter. First of all, let's take the first number, which is 1:
1
To find the second number, which is -12, we must subtract 13, because:
1 - 13 = -12
To find the third number, which is 12, we must add 24, because:
-12 + 24 = 12
In conclusion, the correct answer is A.) subtract 13, then add 24
The solution for the given equation 3x+1 = 4 is x=1.
<u>Step-by-step explanation:</u>
The equation to be solved is given as 3x+1 =4.
<u>The steps to be followed are :</u>
To solve this equation and to find the x value, bring x alone on one side to get a value for x.
For this, the first step is to subtract 1 from both sides of the equation. You get, ⇒ 3x+1-1 = 4-1
⇒ 3x = 3.
The next step is to divide 3 on both sides of the equation.
⇒ 3x/3 = 3/3
⇒ x = 1
Therefore, the above steps must be followed in order to solve the equation 3x+1 = 4. The solution is x=1.
Answer:
Option B and C
Step-by-step explanation:
Option A: NO
38 < 25
38 is NOT less than 25
Option B: YES
38 < 40
38 is less than 40
