Answer:

Step-by-step explanation:

Given that:

Tip left = $1.30

Tax = 7%

Tip = 10% of after tax cost

The tax percentage is not needed in calculating the bill after tax and tip

Hence,

Let after tax cost = x

10% of x = 1.30

0.1x = 1.30

x = $13

After tax cost = $13

Hence, the Total bill after tax = $13

Describe two methods for converting a mixed number to a decimal
uysha [10]
R example: 6 1/2 = 13/2 = 6.5

For the first example, six and a half is equal to thirteen halves, which is then equal to six point five. To do this, the rule to turn a mix number into a fraction is by multiplying the 2 with the 6 and then add the answer to 1, which gives 13/2 (Remember to always give the same denominator). Finally, thirteenth halves is equal to six point five (because when you divide 13 by 2, you get 6 and one left over. To continue dividing, add a 0 , and so 10 goes into 2 is five. so the decimal is 6.5

8xy= 2(2x + y) solve for y
STatiana [176]

Answer:  \displaystyle y= \frac{2\text{x}}{4\text{x} - 1}

============================================

Work Shown:

8\text{x}y= 2(2\text{x} + y)\\\\8\text{x}y= 4\text{x} + 2y\\\\8\text{x}y - 2y= 4\text{x}\\\\y(8\text{x} - 2)= 4\text{x}\\\\y= \frac{4\text{x}}{8\text{x} - 2}\\\\y= \frac{2*2\text{x}}{2(4\text{x} - 1)}\\\\y= \frac{2\text{x}}{4\text{x} - 1}\\\\

---------------

Explanation:

The idea is to first get all the y terms to one side. I did this by subtracting 2y from both sides in the third step.

Then factor out y and divide both sides by (8x-2)

Afterward there's the optional steps of simplifying (as shown in the final two steps).

zzz [600]

Answer:

1/8

Step-by-step explanation:

<u>Solving in steps:</u>

  • x(8x - 8y)⁻¹ + y(8y - 8x)⁻¹ =
  • x/8(x-y) +y/8*(-(x-y))
  • x/8(x-y) - y/8(x-y) =
  • (x -y)/8(x-y) =
  • 1/8

Answer is 1/8

Find the equation given the following two points (7,19) and (9,29)
ra1l [238]

Answer:

y=mx+bx

Step-by-step explanation:

You could either use (7,19) or (9,29) to find the equation....

Y=mx+b

You plug in you x and y, then we are trying to solve for b

x=7, y=19

19=m(7)+b

7m+b=19

-7m          -7m

b= 19 - 7m

Y=7m+1
