Answer:
You are 25
Step-by-step explanation:
This problem is a word problem that requires algebra notation, actually, we are meant to convert this word problem to mathematical expression then solve.
We proceed in a stepwise manner
let say what I have is x
1. Subtract 5 from me
(x-5)
2. Then add 2
(x-5)+2
3. If you subtract 10
(x-5)+2-10
4. And then add 3
(x-5)+2-10+3
5. you get 15
(x-5)+2-10+3=15
what am I is the question we need to answer, we do this by solving for x
x-5+2-10+3=15
x-15+5=15
x-10=15
x=15+10
x=25
Answer:
y-4=4(x+1)
Step-by-step explanation:
y-y1=m(x-x1)
m=4
y-4=4(x-(-1))
y-4=4(x+1)
An equivalent ratio would be 7:10 or 70:100 or 42:60 and so on...
