Step-by-step explanation:
x+y=-12
x-y=-2
solve by simultaneous equations multiply the second equation by -1
-x-y=2
subtract both equations
y=10
x+10=-12
×=-22
Percent means parts out of 100 so
125.25%=125.25/100=12.525/10=1.2525/1=1.2525
basically:
percent to decimal: move decimal place 2 places to the left and get rid of percent sign
decimal to percent: move decimal place 2 places to the right and add percent sign at end
fraction to decimal: divide completely
fraction to percent: divide completely then convert to percent
the answer is 1.2525
The equation representing Max's number is .
<h3>What is an equation?</h3>
In its simplest form in algebra, the definition of an equation may be a mathematical statement that shows that two mathematical expressions are equal. It consists of variables dependent and independent variables. They can be linear or non-linear in nature.
Let the number Max is thinking be 'x'
He adds 8 to the number and then he doubles the sum.
Sum means we are adding a number to x, in this case it is 8.
Double the number means twice the given number in this case it is twice the sum of number with 8.
As per the statement:
The expression to represents Max's number
=
