Answer:

Step-by-step explanation:

She needs to practice piano for 2 hours this week:

Lets add the time she played the piano so far:

Monday + Tuesday + Wednesday

Which is

20 + 30 (half an hour) + 15

= 65 minutes

In which 2 hours is equal to 120 minutes

So,

120 - 65 = 55

She needs to practice for 55 more minutes in this week

Solve the equation for x. the square root of the quantity x minus 8 end quantity plus 2 equals 7 x = 1 x = 13 x = 17 x = 33
Masteriza [31]

The solution of the equation (√x-8) + 2 = 7 is x = 13.

According to the given question.

We have an equation

\sqrt{x - 8} + 2 = 7x

Since, we solve the above equation for x .

Therefore,

\sqrt{x - 8} + 2 = 7

⇒ (√x - 8) = 7 - 2

⇒ (√x - 8) = 5

Squarring both the sides.

⇒ x - 8 = 5

⇒ x = 5 + 8

⇒ x = 13

Hence, the solution of the equation (√x-8) + 2 = 7 is x = 13.
