Answer:
8 times 5 is 40
8 plus 32 is 40
21 divided by 3 is 7
21 minus 14 is 7
E makes no sense becayse you cant multiply 21 by anything to get 7
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.
Answer:
About 68% will make between $200000 and $240000.
Step-by-step explanation:
C. About 68% will make between $200000 and $240000. If the standard deviation is $18,000, then add that to $225000. That equals $243000. Subtract $18000 from the average, you end up with $207000. So it is close, but about 68% will make between $200000 and $240000.
