Answer:
Age of Alice = 25, Age of Jane = 20.
Step-by-step explanation:
Let age of Alice = x
Then age of Jane is 80% of the age of Alice
=> Age of Jane = 80% of x = 80/100 * x = 0.8x
Adding the two ages gives 45.
The two ages are x and 0.8x.
The sum of the two ages is x+ 0.8 x = (1+0.8)x = 1.8x.
=> 1.8 x = 45
Dividing both sides by 1.8, x = 45/1.8
=> x= 25
But x represents the age of Alice.
So age of Alice is 25.
Age of Jane = 0.8* 25 = 20
Verification: Adding the two ages gives 45.
Answer:
y = 1/5x - 6/5
Step-by-step explanation:
Step 1: Write out known variables
m = 1/5
y = 1/5x + b
Step 2: Find <em>b</em>
-1 = 1/5(1) + b
-1 = 1/5 + b
b = -6/5
Step 3: Write linear equation
y = 1/5x - 6/5
