Find 10% of 40 to find the amount of the tax:

\sf 40\times 10\%

Convert 10% to a decimal

\sf 40\times 0.1

Multiply:

\sf 4

So the amount of the tax is $4. Just add this to the purchase amount to find the total amount he paid:

\sf 40+4=44

So the total amount he paid was $44.

Answer:

Tax= $4

Total payed: $44

Step-by-step explanation:

It´s very simple, you just have to calculate the tax by multiplying the cost of the purchase by the percentage, you just do a rule of thirds:

\frac{10}{100} =\frac{x}{40}

Now we just clear the X to solve for the value of the 10%:

x=\frac{40*10}{100} \\x=\frac{400}{100} \\x=4

So we know that the tax is 10% of $40 which is $4.

The total payed is calculated by adding up the cost plus the taxes:

Total payed= Cost+Taxes

Total payed= $40+$4

Total payed: $44

Two welders worked a total of 46 h on a project. One welder made $34/h, while the other made $39/h. If the gross earnings of the
Ratling [72]

Answer:

25 and 21 hours respectively

Step-by-step explanation:

Let the number of hours worked by each welder be x and y respectively.

They worked a total of 46 hours. This means :

x + y = 46 hours.......(I)

Now, given their hourly charges, since we have the total amount of money realized, we can make an equation out of it. This means:

34x + 39y = 1669........(ii)

We then solve both simultaneously. From I, x = 46 -y

We can substitute this into ii

34(46 -y) + 39y = 1669

1564 -34y + 39y = 1669

5y = 1669 - 1564

5y = 105

y = 105/5 = 21

x = 46 - y

x = 46 - 21 = 25 hours

The numbers of hours worked by the welders are 25 and 21 respectively

In dividing two equation with variables and exponent, First you must align or rearrange the equation and group them base on their variables but don't forget the sign of each variables. Second, proceed in dividing its quantity and then subtract its exponent to the other variables having the same. So by calculating it, the answer would be  X or X^1
