Answer:

First find the amount of tax paid, by subtracting the total amount paid from the cost of the item:

530 - 500 = 30

Now divide the amount of tax paid by the cost of the item:

30 / 500 = 0.06

Multiply by 100:

0.06 * 100 = 6% tax

Alfonso and Lucas are 238 miles apart, traveling towards each other. If Lucas travels 21 mph and Alfonso travels 13 mph how long

Alex

Lucas equation for his location is x(t) = 13t.

Alfonso's equation is x(t) = 238 - 21t

If you equate these, you get:

13t = 238 - 21t =>

34t = 238

t = 7

So after seven hours they meet.

Step-by-step explanation:

Step 1: Define

5x + 3 - 2x = 12 + 7x - 2

Step 2: Solve for x

Combine like terms: 3x + 3 = 7x + 10
[SPE] Subtract 3x on both sides: 3 = 4x + 10
[SPE] Subtract 10 on both sides: -7 = 4x
[DPE] Divide 4 on both sides: -7/4 = x
Rewrite: x = -7/4

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: 5(-7/4) + 3 - 2(-7/4) = 12 + 7(-7/4) - 2
Multiply: -35/4 + 3 + 7/2 = 12 - 49/4 - 2
Add: -23/4 + 7/2 = 12 - 49/4 - 2
Add: -9/4 = 12 - 49/4 - 2
Subtract: -9/4 = -1/4 - 2
Subtract: -9/4 = -9/4

Here we see that -9/4 does indeed equal -9/4.

∴ x = -7/4 is the solution to the equation.

Answer:

2/3

Step-by-step explanation:

Simplifying the Complex Fraction

Convert Mixed Numbers to Fractions

56114=5654

Method 1 : LCD Multiplication

The LCD for 6 and 4 is 12

Multiply top and bottom by the LCD

12×5612×54=1015

convert to mixed numbers and

reduce fractions where possible

=1015=23

Method 2 : Fraction Division

Divide the top fraction by the bottom

(multiply top by reciprocal of bottom)

56÷54

=56×45

=2030

convert to mixed numbers and

reduce fractions where possible

=2030=23
