<h3>
Answer: 2(11+9)</h3>
Explanation:
22 = 2*11
18 = 2*9
We see that 2 is the GCF of 22 and 18. It's the largest shared factor.
Now use the distributive property to say the following
22 + 18
2*11 + 2*9
2(11+9)
To check the answer, multiply the outer 2 by each term inside to end up with 22+18 again.
Answer:
12r/t
Step-by-step explanation:
The number of red marbles in the bag is 19 and the number of blue marbles is 8.
<u>Explanation:</u>
Let R be the number of red marbles
Let B be the number of blue marbles
According to the question,
R + B = 27 (Total number of marbles is 27
) -1
R = 3B - 5 (Number of red marbles is 5 less than 3 times the number of blue marbles
)
Substitute the right half of the second equation for R in the first equation
3B - 5 + B = 27
Add 5 to each side and combine the Bs
4B = 32
Divide both sides by 4
B = 8
Use this value of B in the first equation
R + 8 = 27
R = 19
Therefore, number of red marbles in the bag is 19 and the number of blue marbles is 8.
Yes it is. 5\7 is a fraction, therefore it is rational; it can be written as a decimal, 0.714285...... [bar notation indication].
