John's gross monthly salary is $2000.

John receives a 15% raise in his salary.

So first we have to find 15% of $2000.

15% of 2000 = (2000)(\frac{15}{100})

= \frac{(2000)(15)}{100}

= \frac{30000}{100}

= 300

John's salary including the raise = $(2000+300) = $2300.

Now 30% of his monthly paycheck withheld for taxes.

30% of 2300 = (2300)(\frac{30}{100})

= \frac{(2300)(30)}{100}

= \frac{69000}{100}

= 690

So the amount of tax deducted = $690.

John's net monthly income = $ (2300-690) = $1610.

So we have got the required answer.

Approximately how many times greater is 1.2×103 than 4×10−1 ?

3000 Quick answer
Let your calculator do the work. Be careful how you enter this in. (Are you supposed to estimate it? We'll get around to that.) Write it like this.

1.2 * 10^3 divided by 4 * 10^-1 Your calculator will do this nicely. The trick is the - 1. Put it in the calculator like this.
1.2 
*
10
^
3
=
÷
4
*
10
^
(-1) 
= The calculator should read 3000
That's one way to do it. Another way is just to do it all by hand. The numbers are easy enough
1.2 * 10^3 means shift the decimal 3 places right. 1 200 which is 1200
4 * 10^-1 can be handled 2 ways 10 to the minus 1 in the denominator becomes 10^1 in the numerator. Notice the sign change on the 10 when you shift if :it becomes plus! That's why you did it.

1200 * 10^1 
12000

Now you are still left with 4 in the denominator.
12000/4 = 3000. 

The first method always works. The second one gives you a better understanding of how powers work. There are other ways of doing this, but these are the two best, I think.

Marta’s fruit stand sold x oranges on Thursday and twice as many on Friday. All together, on both days, she sold 108. Which bar
Allushta [10]

Step-by-step explanation:

Thursday = x

Friday = 2x (Since thursday is x and she landed up selling twice the amount she did on thursday, friday would be 2x)

Thursday + Friday = 108

For this problem you would need to find the value of x so you would need to substitute x into the equation that was created for the oranges sold on both the days

Thursday + Friday = x+2x = 108

x +2x = 108

3x = 108

x = 108/3

x= 36

Since x is thursday, Marta sold 36 oranges on thursday

To find the amount  of oranges sold on friday you would need to multiply x, which is 36, by 2

2x = 2(36) = 72

72 oranges were sold on friday

Hope this helps!!!

If you mean the system between the two then comes (x;y)=(5;3) otherwise if solved individually they are enough to make the common denominator
