The constant of proportionality is k = y/x.....k = 40/200 = 1/5

y = mx + b
slope(m) = 1/5
(200,40)...x = 200 and y = 40
now we sub...we r looking for b, the y int

40 = 1/5(200) + b
40 = 40 + b
40 - 40 = b
0 = b

so ur equation is : y = 1/5x

if pop star earned 800
800 = 1/5x
800 * 5 = x
4000 = x

A container of coffee is 1/6 full. That container contains 2/3 of a pound of coffee write a division expression that represents
Marizza181 [45]

Let us assume total capacity of the container = x pounds.

Container contains 1/6th coffee of total x pounds,  that is x/6 pounds.

We also given that 1/6th part is equal to 2/3 of a pound.

So, we could setup an equation now.

x/6 pounds equals 2/3 of a pound.

\frac{x}{6} = \frac{2}{3}

Dividing both sides by 1/6, we get

\frac{x}{6} ÷ \frac{1}{6} = \frac{2}{3} ÷\frac{1}{6}.

Therefore,  x = \frac{2}{3} ÷\frac{1}{6}

Division expression that represents the capacity of the container = 2/3 ÷ 1/6.

Serena is building a bookcase she cuts two pieces of wood from one board one piece is 1 7/8 feey long and another is 3.5 ft long
Vladimir79 [104]

Answer:

\frac{43}{8}  feet

Step-by-step explanation:

The total change is the sum of the length of two boards she cut.

First board length is 1  7/8th feet. Let's change to improper fraction:

1 7/8 = 15/8 feet

Second board lengrh is 3.5 feet, or 3  1/2 feet. Let's change to improper fraction:

3  1/2 = 7/2 feet

Let's add the two:

\frac{15}{8}+\frac{7}{2}\\=\frac{15+28}{8}\\=\frac{43}{8}

The change in original board is 43/8 feet
