Answer:
It is number four
Step-by-step explanation: when you have a dividing one such as this you subtract the exponents which would give you 9^-5 but you can’t have a negative so make a fraction and its a positive
3+4+1 for each class so it's 8
8 x 6 for all the classrooms so it's 48. The school buys 48 games
The number is 6400.
We have given that,
divided 80 by my number, and then added 13.
<h3>What is the expression?</h3>
An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Suppose the number is x
Subtract 13 from both sides
Multiply both sides by 80
x=6400
Therefore the number is 6400.

Answer:
x = 57, x = 111
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
x + 67 + 56 = 180
x + 123 = 180 ( subtract 123 from both sides )
x = 57
---------------------------------------------------------------------
Similarly
x + 47 + 22 = 180
x + 69 = 180 ( subtract 69 from both sides )
x = 111
