Answer:
9 beads are purple
Step-by-step explanation:
we know that
To find out how many beads are purple, multiply the total beads by the fraction of the beads that are purple
so

therefore
9 beads are purple
Another way to solve the problem is convert the fraction in percentage
we have

so
If the total are 18 beads
50% is 9 beads
therefore
9 beads are purple
Step-by-step explanation:
3(x - 4y) - 2(y + 7x)
= 3x - 12y - 2y - 14x
= 3x -14x -12y -2y
= -11x -14y
Answer:
-1/5
Step-by-step explanation:
make them have the same denominator by multiplying -1/2 by 5 on the bottom and top which then gives you -5/10 + 3/10 that then gives your -2/10 which reduces to -1/5
