7. If the concert handed out 208 wands and some wands were red wands and some were green wands. The ratio of red wands to green wands is 1:3. How many fans were given green wands?

There were 156 green wands.

Step-by-step explanation:

Given that,

The ratio of red wands to green wands is 1:3.

Let red wands be x and that of green wands be 3x.

ATQ,

Total wands = 208

x+3x = 208

4x = 208

x = 52

Green wands = 3x

= 3(52)

= 156

Hence, there were 156 green wands.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
