lisa drank 1/3 quart of orange juice and lane drank 1/2 quart of orange juice. how many quarts did they drink together

Answers

Answer:

[tex]\frac{5}{6}[/tex] quarts

Step-by-step explanation:

Total amount of drinks = [tex]\frac{1}{3}[/tex] + [tex]\frac{1}{2}[/tex]

You would want to make the denominators the same before adding them, so I will multiply the first fraction by 2 and the second one by 3 so their denominators are 6.  

[tex]\frac{1}{3}[/tex] + [tex]\frac{1}{2}[/tex] = [tex]\frac{2}{6}[/tex] + [tex]\frac{3}{6}[/tex]

Now we can directly add them together while keeping the denominator the same.

[tex]\frac{2}{6}[/tex] + [tex]\frac{3}{6}[/tex] = [tex]\frac{5}{6}[/tex] quarts

The standard form of the given expression is 7x - y = 17

Equation of a line in standard form

The equation of line in standard form is expressed as Ax + By = C

Given the equation

y + 3 = 7(x - 2)

Expand

y + 3 = 7x - 14

y -7x = -14 - 3

-7x + y = - 17

7x - y = 17

Hence the standard form of the given expression is 7x - y = 17

The variables x and y very directly. Use the values to find the constant of proportionality K then write equation that relates to x and y. Write any fraction in simplest form. Y equals 20 and X equals 12

Answers

Answer:

k=5/3

Step-by-step explanation:

The variables x and y vary directly. Given that, y = 20 and x = 12

We can write it as :

y=kx

Where k is constant of proportionality

Put the values of x and y

20=12k

k = 20/12

k = 5/3

So, the value of the constant of proportionality is 5/3.
