192 = total beads
necklace + bracelet = 192
Let x equal the number of beads
bracelet = 5x
necklace = x
5x + x = 192
6x = 192
x = 32
It takes 32 beads to make a necklace
Answer:
x = -4 y =-4
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
<u>The answer for this equation is x = 7</u>
Step-by-step explanation:
1. Solve for x given that CE=36
9 + 3x + 6 = 36
3x + 15 = 36
3x = 36 - 15 (Putting x on the left side and all the numeric values on the right)
3x = 21
<u>x = 7 (Dividing by 3 at both sides)</u>
2. Proof of replacing x by 7
9 + 3 (7) + 6 = 36
9 + 21 + 6 = 36
<u>36 = 36</u>
<u>It proves that x = 7 is correct</u>
To start, note that the roots of a function have to do with how many times the function passes through the x-axis.
When you look at the graph above, notice that it passes through the x-axis 3 times, at the points (-6,0), (-4,0), and (3,0).
Knowing this, you can conclude that your answer would be choice B.)3
