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:
Supplementary angles add to 180 degrees.
Angles of a triangle add to 180 degrees.
So, the angles of this triangle are 2x, 3x, and 70.
This means we can have the equation: 5x+70=180, and 5x=110, meaning that x=22

Given parameters:
Percentage gain = 300%
Selling cost last year = $2420
Unknown:
Selling cost this year = ?
Solution:
To solve this problem;
Profit percent = 
300 = 
3 = 
S- 2420 = 7260
S = $9680
To make a 300% gain, Jefferson Middle school needs a $9680 from fundraiser sales this year.
