Answer:

Salary is 7000

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.

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.

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.

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

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

Step-by-step explanation:

There 3 different flavors of ice-cream available and 5 different toppings are available.

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

[tex]{n\choose k}=\frac{n!}{k!\cdot (n-k)!}[/tex]

(a)

Compute the number of possible sundaes that can be made with one flavor  and three different toppings as follows:

[tex]\#\text{Sundaes}=\#\text{Ways to select 1 flavor}\times \#\text{Ways to select 3 toppings}[/tex]

                [tex]={3\choose 1}\times {5\choose 3}\\\\=3\times 10\\\\=30[/tex]

(b)

Compute the number of possible sundaes that can be made if there are three scoops of each ice cream and two different toppings as follows:

[tex]\#\text{Sundaes}=\#\text{Ways to select 1 flavor}\times \#\text{Ways to select 3 toppings}[/tex]

                [tex]=1\times {5\choose 2}\\\\=1\times 10\\\\=10[/tex]
