Answer:
80
Step-by-step explanation:
Freddie is one meter shorter than his father
His father is 180 centimeters tall
So freddie is 80 centimetres
Freddie is mother÷2
So 80=M÷2
Mother is 190 centimeters
Solving the expression
we get -2.
Comparing the solution with the one given, you can find the errors.
Step-by-step explanation:
We need to simplify
and identify errors.
Since the steps are not shown, so we cannot identify errors but I can solve the expression and you can compare to find errors.
Simplifying:

Using algebraic rule: if one digit has positive (+) sign and other digit has negative (-) sign then we will perform subtraction. and after subtraction, the sign of bigger value will be the sign of result.
Using the rule and solving:





Solving the expression
we get -2
Comparing the solution with the one given, you can find the errors.

1. 208/x = 100/130
2. multiply both sides by x
3. 208 = 0.76923x
4. divide both sides by 0.76923
5. x = 270.4
There's lots of even functions, but two that come to mind are the absolute value function, IxI, and x^2. These are even because they are reflected over the y axis. Another way to find this is that (-x)^2 is equal to x^2 and so is I-xI, the algebraic method. Good luck!
