It takes Sam 3 hours to rake leaves, but if Laura helps, it takes 2 hours. How long would it take Laura to rake the leaves on her own?
Answer:
6 hours
Step-by-step explanation:
Given that:
Time taken by Sam = 3 hours
Sam's rate = 1/3
Time taken : Sam + Laura = 2 hours
Sam's rate + Laura's rate = 1/2
Let time taken by Laura = x
1/3 + 1/x = 1/2
1/x = 1/2 - 1/3
1/x = (3 - 2) / 6
1/x = 1 /6
x = 6
Hencw, it will take 6 hours for Laura alone to rake leaves
Wai keong's monthly salary is twice the amount he save in April he save $3500 in April. In may, he saved $4200 less than the amount he spent. How much is his monthly salary? How much did he save in may?

He saved 2800 in may
The monthly salary of the Wai keong will be $7,000 and the amount of his savings will be $2,800.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Wai keong's monthly salary is twice the amount he save in April he save $3500 in April.
Let x be the monthly salary of the Wai keong.
Then the equation will be
x = 2 × $3500
x = $7,000
The monthly salary is $7,000.
In may, he saved $4200 less than the amount he spent.
Then the amount of money that he can save will be
⇒ $7,000 - $4,200
⇒ $2,800
The monthly salary of the Wai keong will be $7,000 and the amount of his savings will be $2,800.

What are m and b in the linear equation 5 + 12x + 1 + 15x = y?
Answer: m = 27, b = 6
Step-by-step explanation:
1. Start by combining like terms
6 + 27x = y
2. Rearrange into standard form (y = mx +b)
y = 27x +6
Interpret the values:
m = slope -> 27
b = y-intercept -> 6
