Answer:
1
Step-by-step explanation:
Given that both equations are equal, solve the distributive property and then just solve for X:
2x + 2(3x-1) = 3(x+1)
2x + 6x - 2 = 3x + 3
5x = 5
x = 1
Therefore, the value of X is 1.
To know the perimeter of the triangle, we apply the value of X to solve the equation.
3(x + 1)
3(1 + 1)
3 + 3 = 6.
Therefore, each figure's perimeter is 6, as both are equal.
Answer
58
Step-by-step explanation:
So you would plug in 4 for h and 6 for g to get 4+9(6), then you multiply 9x6 to get 54 then you would add 4 to get 58
Answer:
The probability of select randomly a red or a blue marble is
Step-by-step explanation:
The probability of an event is the ratio of the number of ways it can happen, to the total number of possible cases.
Select randomly a red or a blue marble are mutually exclusive events because they cannot occur at the same time. When two events, A and B, are mutually exclusive, the probability that A or B will occur is the sum of the probability of each event.
We know from the information given that
- There are 46 red marbles, 59 white marbles and 49 blue marbles
We can use this information to calculate the probability of select randomly a red marble and also the probability to select randomly a blue marble
Now we can calculate the probability that we select a red or a blue marble
