Answer:
the answer for #2 is -7
the answer for #3 is 11 or D
number 4 is 5 or C
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:

Answer:
d = 13 and n = 52
Step-by-step explanation:
Number of dimes: d
Number of nickels: n
Then d + n = 65, and n = 4d
Substituting 4d for n in the first equation, we get:
d + 4d = 65, or 5d = 65. Then d = 13 and n = 52
