On monday marco practiced the piano for 7/10 hour. On Tuesday he practiced for 1 1/4 hours each day write a question that involv

Fantom [35]

Step-by-step explanation:

Since we have given that

Number of hour Marco practiced the piano on Monday is given by

$\frac{7}{10}$

Number of hours Marco practiced the piano on Tuesday is given by

$1\frac{1}{4}=\frac{5}{4}\ hours$

1) For Adding :

Total number of hours he practiced on both Monday and Tuesday will be

$\frac{7}{10}+\frac{5}{4}\\\\=\frac{14+25}{20}\\\\=\frac{39}{20}\ hours$

2) For Subtraction,

Number of hour he practiced more on Tuesday than on Monday will be

$\frac{5}{4}-\frac{7}{10}\\\\=\frac{25-14}{20}\\\\=\frac{9}{20}\ hours$

The equation of a line is given by, 13x – y + 12 = 0. Find the slope and both the intercepts.

MArishka [77]

Answer:

The slope is 13.

The x intercept is $x=\frac{-12}{13}$ .

The y intercept is $y=12$ .

Step-by-step explanation:

1. Finding the slope.

This is a linear equation, because it's graph forms a line. In a linear equation, the slope is always the value that multiplies x. In this case, x is being multiplied by 13, therefore, the slope is 13.

2. Finding the x intercept.

The x intercept is found when the value of y is 0. Let's replace the value of y for 0 in the equation and solve the x:

$13x-y + 12 = 0\\\\13x-(0) + 12 = 0\\\\13x+12 = 0\\\\13x= -12\\\\x=\frac{-12}{13}$
