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.

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

y varies inversely as x. When x=10, y=20. Find y when x=50
Answer:
y=100
Step-by-step explanation:
You can solve this by comparing the ratio.
The first set is 10:20 or 1:2 when simplified.
This can then be applied to the second set. If x=50, then 50 times 2 will give you the answer of 100.
Which statements are true about the ordered pair (7, 19) and the system of equations?
The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.
The ordered pair (7, 19) is a solution to the second equation because it makes the second equation true.
The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.
The ordered pair (7, 19) is a solution to the system because it makes both equations true.
Answer:
(7,19) is a solution for only the first equation (2x-y= -5), so it is not a solution to the systemmmm
