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 ma’am i’m not helping but ya know i need point so i’m just doing stuff lol
Step-by-step explanation:
collin is correct and incorrect at the same time. when you solve this, you start with adding like terms.
10x and -11x will be added together to be -1x, after we figure this out, we solve.
-1x+7<-20
-7 -7
-1x<-27
/-1 /-1
x<27
after you solve, you notice that x is less than 27. collin has the correct answer for solving the equation, but if were looking on a more technical note, he would be incorrect because he said the answer is 27, when the answer is actually less than 27. therefore, collin has solved the inequality correctly, but he has said the answer incorrectly
62 is the correct answer of this question
-1/2 because slope is the rise over the run. If you count on the grid from one point on the line to another you go up one and 2 to the left meaning the slope is 1/2, buttttt when the line decreases going to the right, it has a negative slope so you just add a - sign in front
