Lets say the number is x so we can make an equation
If is at least 21, that means it has to be greater then or equal to it.
6+5*x>=21
You can subtract 6 from both sides
5*x>=15
Then divide both sides by 5
x>=3
You can conclude that the number is greater then or equal to 3.
Hey there!
The first thing we can do is find the number of third in 4.
We can do this by multiplying 4 by 3 since there are 3 thirds in a whole.
4 x 3 = 12
So, 4 = 12/3
If she studies for 2/3 an hour each night, then we can divide 12 by 2 to figure out how many 2/3 go into 12/3.
12 ÷ 2 = 6
So, she studied for 6 days.
Hope this helps!
Hello There!

The y intercept is where the graph crosses the y axis. It goes vertical
Answer:
3^5 is 3*3*3*3*3
Which is 9*3*3*3 = 27*3*3 = 81*3 =243
3* -3 = -9
243*-9 = -2187
