Answer:x=10

Step-by-step explanation:

You will first multiply (8x-11) to 10 to distribute.

You end up with 80x - 110.

You will then add 110 from 690.

You end up with 800.

You will then divide by 80, which will leave you with x=10.

Answer:

(x - 7)² + (y - 4)² = 49

Step-by-step explanation:

Given

Equation: x² + y² = 49

Required:

New Equation when translated 7 units right and 4 units up

Taking it one step at a time.

When the equation is translated 7 units right, this implies a negative unit along the x axis.

The equation becomes

(x - 7)² + y² = 49

When the equation is translated 4 units up, this implies a negative unit along the y axis.

(x - 7)² + (y - 4)² = 49

The expression can be further simplified but it's best left in the form of

(x - 7)² + (y - 4)² = 49

Answer:

The answer is nearly $81 billion.

Step-by-step explanation:

If we know that 80% of airline tickets worth $65 billion, then $65=80\%\plus{Total_{tickets}}=0.8\plus{Total_{tickets}}\\$ .
Then,to know how much billion dollars worth the total tickets, we just have to clear out $Total_{tickets}$ of the equation, by dividing both sides by 0.8, which yields $\frac{65}{0.8}=Total_{tickets}=81.25$
