Mary is four years older than Sue. If the sum of their ages is 16, how old are Mary and Sue?
dusya [7]

Answer:

Sue is 6 and Mary is 10

Step-by-step explanation:

let Sue's age be x then Mary is x + 4 and the sum of their ages is

x + x + 4 = 16

2x + 4 = 16 ( subtract 4 from both sides )

2x = 12 ( divide both sides by 2 )

x = 6

x + 4 = 6 + 4 = 10

then Mary is 10 and Sue is 6

What is this called, like whats the name of this thing??<br> {18 ≤ y ≤ 30}
Tpy6a [65]

Answer:

An inequality.

Step-by-step explanation:

This gives the range of values that y can take.

It can equal 18 or be greater than eighteen but it also could be 30 or less than thirty.

WE read the signs starting from y to the left  and to the right.

So y is greater or equal to 18 and less than or equal to 30.
