Answer:

18 hours.

Step-by-step explanation:

Gebe rents a piano for $49 per month.

He earns $15 per hour for giving piano lessons to students.

Let his earning for x hour = 15x

15x + 49 = 316

15x = 316 - 49

15x = 267

x = \frac{267}{15}

x = 17.8 hours ≈ 18 hours

Gebe must give 18 hours lessons to earn a profit of $326.

Express 2x^2+8x+3 in the form 2(x+p)^2+q
e-lub [12.9K]

Answer:

2(x + 2)² - 5

Step-by-step explanation:

Given

2x² + 8x + 3

To obtain the required form use the method of completing the square.

The coefficient of the x² term must be 1, thus factor 2 out of 2x² + 8x

= 2(x² + 4x) + 3

add/subtract ( half the coefficient of the x- term)² to x² + 4x

= 2(x² + 2(2)x + 4 - 4) + 3

= 2(x + 2)² - 8 + 3

= 2(x + 2)² - 5

with p = 2 and q = - 5

What is the best estimate for 591.3 divided by 29
Katena32 [7]

Answer:

  about 20

Step-by-step explanation:

The numbers round to 600/30 = 20, which is a reasonable estimate.

You can refine this by doing the next step of long division:

  29×20 = 580

Subtracting this from 591.3 give 11.3, so the fraction is ...

  11.3/29 ≈ 10/30 = 1/3

A better estimate is 20 1/3.

_____

A calculator tells you the quotient is about 20.3897.
