How to make a mixed number a improper fraction ​
Elena L [17]

A mixed number of the form a\frac{b}{c} can be turned into an improper fraction by using the fact that a mixed number is really het whole number plus its fraction part, so

  a\frac{b}{c} = {\displaystyle a + \frac{b}{c}=\frac{a}{1}+\frac{b}{c}}

Then do the usual procedure for adding fractions via common denominator.

For example, to convert the mixed number 5 \frac{1}{4} into an improper fraction, we have

  5\frac{1}{4}={\displaystyle 5 +\frac{1}{4}=\frac{5}{1}+\frac{1}{4}}

To add \frac{5}{1}+\frac{1}{4}, we need \frac{5}{1} to have a denominator of 4, so we multiply the numerator and denominator by 4 to get

   =\frac{5\cdot 4}{1 \cdot 4}+\frac{1}{4}=\frac{20}{4}+\frac{1}{4} = \frac{21}{4}

Therefore,

  5\frac{1}{4} = \frac{21}{4}

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1LaTeX: \frac{3}{5}3 5 doors. How m
marissa [1.9K]

Answer:

1 1/4 liters of paint

Step-by-step explanation:

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1LaTeX: \frac{3}{5}3 5 doors. How many liters of paint are needed for 1 door?

From the above question, we can deduce that:

2 liters of paint covers 1 3/5 doors

Hence:

1 3/5 doors = 2 liters of paint

1 door = x liters of paint

Cross Multiply

1 3/5 doors × x liters = 2 liters × 1 door

x liters = 2 liters × 1 door/ 1 3/5 doors

x liters = 2 ÷ 1 3/5

x liters = 2 ÷ 8/5

x liters = 2 × 5/8

x liters = 5/4 liters

x liters = 1 1/4 liters of paint

Hence: 1 1/4 liters of paint is needed for 1 door

What is the equation of a hyperbola with a = 9 and c = 12? Assume that the transverse axis is horizontal
Lorico [155]
The general equation of a hyperbola with a horizontal transverse axis is defined as:
x²/a² - y²/b² = 1

Solving for b², we use the formula: a² + b² = c²
b² = 12² - 9² = 63

Equation of our hyperbola will be:
x²/81 - y²/63 = 1

Simpify the expression.<br>5+4z-2z<br><br>Simpilfied expression ​
Dafna11 [192]

Answer:

2z + 5

Step-by-step explanation:

you have to combine like terms

subtract 4z - 2z and you get 2z

the number with the variable next to it goes first not the constant

2z + 5

the variable is z and the constant is 5 because it doesn't have variable next to it

hope this makes sense and helps :)
