Devaughn is 10 years older than sydney.The sum of their age is 64.What is Sydney age?
1 answer:
Hello!
You can make this into two expressions based on what you know
let x stand for Devaughn's age
let y stand for Sydney's age
x = y + 10
x + y = 64
You can put x into the second equatoin
y + 10 + y = 64
Combine like terms
2y + 10 = 64
Subtract both sides by 10
2y = 54
Divide both sides by 2
y = 27
You can put y into the first equation
x = 27 + 10
combine like terms
x = 37
Devaugn is 37 and Sydney is 27
Hope this helps!

Since all you’re saying is evaluate ∫12–2
I’m assuming the answer would be 1/(1+x)(1-x)
