These symbols are called operators.
Mathematics is the science that relates everyday practices and nature to human reasoning and numerical logic.
<h3>Math Operations</h3>
The four basic math operations are present in your day-to-day life, for example: when you pay your bills. The math operations are:
- addition - represented by symbol "+"
- subtraction - represented by symbol "-"
- multiplication - represented by symbol "x"
- division - represented by symbol "÷"
These symbols, also, are known as arithmetic operators.
Note that in math expressions, it is necessary to apply the rule of operations: parentheses, exponents, multiplication/division, and addition/subtraction.

Answer:
First one is 25/2
Step-by-step explanation:
12×2+1=25/2
9×4+1=36/4
cross multiply and you get
100/
divide both by 2 and you get 50/4 then you divide both by 2 again and you get 25/2 because you can't reduce it anymore
20 jasmine flowers? just do tally marks and count how many times you did them because each tally has five so you subtract the four from the five and count the tallys you have left
Answer:
x = 6, y =3
Step-by-step explanation:
4x-7y=3
x-7y=-15
Multiply the first equation by -1
-4x+7y=-3
Then add this to the second equation to eliminate y
-4x+7y=-3
x-7y=-15
------------------
-3x +0y = -18
-3x = -18
Divide by -3
-3x/-3 = -18/-3
x = 6
Now find y
x -7y = -15
6 -7y = -15
Subtract 6 from each side
6-7y-6 = -15-6
-7y = -21
Divide by -7
-7y/-7 = -21/-7
y =3
