Question

Devaughn is 14 years older than Sydney. The sum of their ages is 94 . What is Sydney's age?

Answer 1

Lets let Devaughn's age be 'a'

And sydney be 's'

So we know together they sum to 94

a + s = 94

But we also know...that Devaughn is 14 years older than sydney...so

a = s + 14

So now tht we know what 'a' equals...we can plug it into our first equation we made

a + s = 94

will become

s + 14 + s = 94

Answer 2

40 years old! thank you

Answer 3

that's right john...Amanda just solve for s then for a

Answer 4

We can simplify and make this

2s + 14 = 94

And then use algebra to solve for 's'

**which yes is 40 lol great job!**

Answer 9

actually this one has me confused,
tal of
357
tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?

Answer 10

Well good that it helped...now for this one

So we can let ADULT tickets = 'a'
and STUDENT tickets = 's'

The total was 357 so

a + s = 357

And we know that there were 2 times as many student tickets sold than adults...so

s = 2a

Now we just plug it in

\[\large a + 2a =357\]
