8.EE.8.b

Andre is in charge of cooking broccoli and zucchini for a large group. He has to spend all $17 he has and can carry 10 pounds of veggies. Zucchini costs $1.50 per pound and broccoli costs $2 per pound. One graph shows combinations of zucchini and broccoli that weigh 10 pounds and the other shows combinations of zucchini and broccoli that cost $17.
Name one combination of veggies that weighs 10 pounds but does not cost $17.

The temperature in degrees Fahrenheit, F, is related to the temperature in degrees Celsius, C, by the equation

F=\frac{9}{5}C+32
In the Sahara desert, temperatures often reach 50 degrees Celsius. How many degrees Fahrenheit is this?

8.EE.8.a

8.EE.8.b

The temperature in degrees Fahrenheit, F, is related to the temperature in degrees Celsius, C, by the equation

F=\frac{9}{5}C+32
In parts of Alaska, the temperatures can reach -60 degrees Fahrenheit. How many degrees Celsius is this?

8.EE.8.a

8.EE.8.b

The temperature in degrees Fahrenheit, F, is related to the temperature in degrees Celsius, C, by the equation

F=\frac{9}{5}C+32
There is one temperature where the degrees Fahrenheit and degrees Celsius are the same, so that C=F. Use the expression from the equation, where F is expressed in terms of C, to solve for this temperature.
