Please help Maggie's brother is 3 years younger than twice her age. The sum of their ages is 30.
denpristay [2]
I’m not sure if this is correct but this is the way i would solve it.

first, make an equation with the given information

2x-3=30

Then, add three to both sides

2x=33

Finally, divide both sides by 2

x= 16.5


x represents the age of maggie so all you have to do is plug the solution into the equation to check your answer.

2(16.5)-3= 30

Is 5/8 grater than or equal to 11/16
dezoksy [38]

Answer:

Less than

Step-by-step explanation:

Although it wasn't an option, it is less than. In order to accurately compare then, you have to get the least common denominator. Using the least common multiple (2), you multiply 5/8 by 2 and end up with 10/16. Now 10 is less than 11, so the option is neither of those. 5/8 is less than 11/16.
