Let the age of ahmed three years ago be x years old. since 3 years ago ahmed as one third of his sister's age, his sister would be 3x years old 3 years ago.
in a year's time, ahmed would be x+4 years old and his sister would be 3x+4. we also know that in a year's time ahmed's age doubled will match his sister's age. hence 2(x+4)=3x+4
2x+8=3x+4
4=x
x is the age of ahmed three years ago. hence, now ahmed is 7 years old.

Answer:
1. y=mx+b
(5 , 5) (10 , 10)
5m+b=5 10m+b=10
10m+b-5m-b=5
5m=5
m=1
5+b=5
b=0
So for 1---10s the slope is: y = x
2. y=mx+b
(10 , 10) (35 , 10)
10m+b=10 35m+b=10
35m+b-10m-b=0
25m=0
m=0
b=10
So for 10-----35s the slope is: y=10
3. y=mx+b
(35 , 10) (0 , 0)
35m+b=10 b=0
35m=10
m=2/7
So for 35----40s the slope is: y= 2/7 x
Answer:
He can use 2 scoops of the 1/8 cup
Step-by-step explanation:
You can find this answer because 2/8 is really just 1/4 cup.when you divide both sides of 2/8 by 2 it equals 1/4. Hope this helped
