Step-by-step explanation:
-3x+3x-(b÷2)=-3
0-(b÷2)=-3
-(b÷2)=-3
b=-2×-3=+6
=> b=6
<h2>The answer is:
D</h2>
(12 x 4= 48) + (4 x 2=8) = 56
The 4 is for the $4 amount spent on adult tickets. The 2 is for the $2 amount spent on child tickets.
HOPE THIS HELPS!
Answer:
b
Step-by-step explanation:
There are 
ways for the teacher to decide which student she will teach during each lesson time if she must teach each student exactly 3 times. Here, "!" represents the factorial.
A number's factorial is the result of multiplying the integer by each natural number below it. Factorial can be symbolized by the letter "!". Thus, n factorial is denoted by n! and is the result of the first n natural numbers.
A whole number's "n" factororial is the sum of that number and each whole number up to one.
When a question asks you to determine how many different ways you can arrange or order a given number of items, you use a factorial.

3.) 3, 4, 5
&
4.) 6, 8, 10
Those two are right triangles because when you add the squares of the first two it should give you the square root of the third number
a^2 + b^2 = c^2
So
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
Therefore they are right triangles
But 1 & 2 aren’t right triangles because when you add the squares of the first two number, it doesn’t equal to the square root of the third number.
Hope this helps!!
