Diego is buying shrimp and rice to make dinner. Shrimp costs $6.20 per pound and rice costs $1.25 per pound. Diego spent $10.55 buying shrimp and rice. The relationship between pounds of shrimp s, pounds of rice r, and the total cost is represented by the equation 6.20s+1.25r=10.55.


Write an equation that makes it easy to find the number of pounds of rice if we know the number of pounds of shrimp purchased.

Question image

The graph shows the relationship between the total cost, in dollars, and the number of hats ordered.

What does the slope of the graph tell us in this situation?

1

It tells us that there is a fixed cost of approximately $35 for ordering hats.

2

It tells us the amount that the total cost increases for each additional hat ordered.

3

It tell us that when 9 hats are ordered, the total cost is approximately $160.

4

It tells us that when the number of hats ordered increases by 10, the total cost increases by approximately $175.

In physics, the equation PV=nRT is called the ideal gas law. It is used to approximate the behavior of many gases under different conditions.

P, V, and T represent pressure, volume, and temperature, n represents the number of moles of gas, and R is a constant for the ideal gas. Which equation is solved for T?

1

PVR=nT\frac{PV}{R}=nT

2

PVnR=T\frac{PV}{nR}=T

3

T=PVnRT=PV-nR

4

RVnR=TRVnR=T
