Solving equations with rational numbers
Nonamiya [84]

Answer:

P= 2

T=6

3) 252$

Step-by-step explanation:

1) set up your equation 3/8p=6/8 then divide 3/8 from both sides (remember when you divide fractions you would multiply by the reciprocal so 3/8 x 8/6. Also make sure you simplify)

2) Do the same here. 38/7 divided by 19/21

3) Turn the fraction into an improper fraction then multiply 126 by that amount (3/6)

Target pays $13 per pair of sunglasses and uses 30% markup rate. What is targets selling price for the sunglasses?
Elena L [17]

Answer:

$16.90

Step-by-step explanation:

First you need to find how much the markup is in dollars.

Multiply 13(0.3).

This will give you 3.9.

Then you add this to the original cost of the glasses.

13+3.9= 16.9.

So, the final cost of the glasses is $16.90.

Solve this equation for x. round your answer to the nearest 0 = ln (x+6)
MissTica

Answer: x=-5

Step-by-step explanation:

To solve this exercise you need to remember the following:

e^{lnx}=e^{lny} → x=y

Therefore, keeping the above on mind, you can solve for x as following:

e^0=e^{ln(x+6)}

e^0=x+6

Remember that, by definition: a^0=1, then you have:

1=x+6

Subtract 6 from both sides of the equation.

Then the value of x is:

1-6=x+6-6\\x=-5
