A) 42x-12
6*7=42. 6*2=12
b) 21y
11+4+6=21
Answer: It's being divided by 5. hope this helps
Angles in a triangle add up to 180 degrees.
(2x-10)+(x+30)+70=180
(2x-10)+(x+30)=110
3x+20=110
3x=90
x=30
so A:
2(30)-10
=50
Using the Fundamental Counting Theorem, we have that:
4. 1,757,600 different license plates can be there.
5. 676,000,000 different driver's license numbers can be formed.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:

For the letters there are 26 outcomes and for the digits there are 10 outcomes, hence the parameters for item 4 are given as follows:

Hence the number of license plates is given by:
N = 26 x 26 x 10 x 10 x 26 = 1,757,600.
For item 5, the parameters are:

Hence the number of license numbers is:
26 x 26 x 10 x 10 x 10 x 10 x 10 x 10 = 676,000,000

Step-by-step explanation:
The slope-intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept (0, b)</em>
We have

Substitute:

We only need two points to draw a line.
One we have: y-intercept → (0, -7).
Calculate other point:
Substitute <em>x = -3</em> to the equation of a line:

Mark the points on the coordinate plane and draw a line through the given points.
