Let's represent the number of weeks with the variable 'w':

130 + 25w = 600

We subtract both sides by 130:

25w = 470

w = 18.8

We round up:

It will take her 19 weeks.

Answer:

Jan got 19 weeks.

Step-by-step explanation:

The number of weeks should be the variable of "w."

\displaystyle 130+25w=600

Subtract by 130 from both sides of equation.

\displaystyle 130+25w-130=600-130

Solve.

\displaystyle600-130=470

\displaystyle 25w=470

Divide 25 both sides.

\displaystyle\frac{25w}{25}=\frac{470}{25}

Simplify, to find the answer.

\displaystyle \frac{94}{5}=18.8=19

There are 19 weeks.

Xelga [282]
In this problem, since we are trying to find Sam's monthly net income, we just need to multiply his weekly net income (which is after all the deductions come out) by how many times he gets paid! Because he gets paid 4 times, we just need to multiply $654.48 by 4! The you should get an answer of $2617.92, which is Sam's monthly net income!

Kobotan [32]

Answer:

30,40,50

Step-by-step explanation:

If it is a right triangle then the pythagorean theorum would work

a^2+b^2=c^2

30^2+40^2=50^2

900+1600=2500

2500=2500

this means that 30,40,50 is the right answer

*******extra********

also 30,40,50 is a pythagorean triplet

pythagorean triplets form right angles

this one came from the original triplet of 3,4,5---just multiply by 10
