16 to 30
is the ratio of girls to the classmembers
Hope this helps!
Multiplying exponents will just have to follow a rule.
Make sure that the base are the same otherwise, you keep it as is.
If they have the same bases, then just add the exponents.
= (5a^5)(6a^6)
= 30a^11
So the final answer is <span>30a^11.</span>

Answer: x = 6
Step-by-step explanation:
First step is to distribute the 5(x + 2).
5x + 10 = 6x + 3x - 14
The 6x and the 3x on the right can be combined.
5x + 10 = 9x - 14
Now add 14 to both sides to isolate the 9x.
5x + 24 = 9x
Subtract 5x from both sides.
24 = 4x
Divide by 4 to get x by itself.
6 = x
Answer:
3x +4 = -2x -1
Step-by-step explanation:
The line that goes up to the right has a y-intercept of +4. This is where it crosses the y-axis. It's slope (rise/run) is 3/1 = 3, so its equation in slope-intercept form is ...
y = mx +b . . . . where m is the slope, b is the y-intercept
<u>y = 3x +4</u>
The other line has a negative slope and a y-intercept of -1. The slope of that line is rise/run = -2/1 = -2, so its equation is ...
<u>y = -2x -1</u>
__
The solution point will have the x-coordinate that is the solution of the equation ...
y = y
3x +4 = -2x -1 . . . . . . substituting the above expressions for y.
