Math
Ok, but what is is the equation?

Math
Greg rode his bicycle at a constant speed of 20 miles per hour. Plot points on the graph to present the distances Greg rode after 1,2,3, and 4 hours (1 hour = 20 miles, 2 hours = 40, 3 hours = 60, 4 hours = 80 miles). Write an equation to represent the relationship between ...

The atomic number of cadium is half the atomic number of curium. Define a variable and write an expression for the atomic number of cadmium.

Physics!
A piston has a diemaeter of .64 cm. A second piston has a diameter of 3.8 cm. determine the Force necessary on Piston A to support the 500.0 Newton weight on piston B (in the absence of friction.)

Read my question, and then look at this message for my results!
I think I understand how to do this... here's my work. 4a - 2 < a + 1 < 3a + 4 I separated them into two pieces: 4a-2 < a + 1 and a + 1 < 3a + 4 Then, I added two to each side of the first one, and took away 1 from each side of the second one. 4a < a + 3 and...

Algebra
4a-2 (less than or equal to) a + 1 (less than or equal to) 3a + 4 I'm assuming I should put this on a line, like I did with some other problems on my worksheet, right? But I have no idea how I would show 4a-2 on a line! I have no idea how to do this. Thank you so much!

Algebra
Solve 3x +1 < 5 or 3x +1 > 4 By saying "solve," is it asking for me to show it on a line and in interval notation? Here's another: f(x) < 3 and f(x) > 4, where f(x) = 1/2x - 7 I have no idea how to solve this! Please walk me through it! Thank you so ...

Salty-- maybe pretzels or crackers, or pizza. Some kind of fruit or vegetable might be sour-- I know, like a lemon! Hope I helped!

Physics
A charge of 28.0 nC is placed in a uniform electric field that is directed verticall upward and that has a magnitude of 4.00*10^4 N/C. What work is done by the electric force when the charge moves (a)0.450 m to the right (b) 0.670 m upward (c) 2.60 m at an angle of 45 degrees ...
