What does GEMDAS stand for

Hi!

GEMDAS is the guideline that you would use to solve a algebraic expression. It tells you the order of which things you should solve or simplify first.

G. Groupings. (There is a similar expression called PEMDAS that is a bit easier to understand, where  the P stands for parentheses, brackets, etc.)

E. Exponents.

MD. Multiplication and Division, right to left.

AS. Addition and Subtraction, right to left.

Hope this helps!

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

the answer is c just got it on ed
