The answer is D. Maria selected a multiple that is not the least of the common multiples.
We see from the list that the least common multiple between 6 and 15 is 30, not 60.
Answer:
She originally had 7 necklaces.
Step-by-step explanation:
She now has 18 necklaces. She bought four more. That would be 18 - 4 = 14. She gave half of them to her sisters. 14 divided 2 is 7.
These 2 angles are vertical angles.
Vertical angles are equal.
Set up an equation where 2 angles are equal to each other.
Solve for 'x'.
6x+238 = 3x + 178
3x = 178 - 238 = -60
x = -60/3
x = -20
The value of x and y in the given equation is determined -1 and -2 respectively.
<h3>
Value of x and y</h3>
The value of x and y can be determined by solving the two equations simultaneously.
y = -2x - 4 ----- (1)
y = 4x + 2 ----- (2)
solve (1) and (2) together
-2x - 4 = 4x + 2
-6x = 6
x = -1
y = 4(-1) + 2
y = -4 + 2
y = -2
