Write two equations with the given information:
1) x = 2y ( x is twice the value of y)
2) x + y = 42
Replace x in the second equation with the value of x in the first equation:
2y + y = 42
Simplify:
3y = 42
Divide both sides by 3:
y = 42 / 3
y = 14
Now we have the value for Y, solve for x by replacing y with 14:
x = 2y
x = 2(14)
x = 28
X = 28 and y = 14
Solution: The number of ways we can arrange 3 blue marbles if a set of 5 marbles is selected is:
Therefore, there are 10 ways we could arrange 3 blue marbles.
68.01
A quotient is the answer to two numbers being divided.
Meaning 68.0052÷12 is 68.01
Answer:
the slope would be -5
Step-by-step explanation:
in linear equations, the slope of the line is the coefficient of x
so in this case, it is -5
