We multiply 1/5 times 40 as step 1. (1/5)(40) = 8 We now subtract the product 8 from 40. So, 40 - 8 = 32. The answer is 32.

Yes, you are right so far. 7 - 2x < 3x + 32 Treat it like a regular equation question. Combine like terms and solve for x. 7 - 32 = 2x + 3x -25 = 5x -25/5 = x -5 = x Checking: 7 - 2x < 3x + 32 7 - 2(-5) < 3(-5) + 32 7 + 10 < -15 + 32 17 < 17....This is not true...

Set up a proportion and solve for a letter of choice. I will let w = weight for 3.75 gallons of water since we are searching for weight. So, w = weight we are searching for. 1 gallon/3.75 gallons = 8.34 weights/w Cross-multiply to find w. w = 8.34 times 3.75 w = 31.275 IBS Is ...

We can also write y = x as f(x) = x because f(x) = y and vice-versa since both represent a function. In your case, y = x is a linear function because it forms a LINE PICTURE when graphed on the xy-plane. The line y = x goes through the origin or this point (0,0) from the first...

4x^2 = 8x-5 You must bring every term to one side of the equation. I would bring 8x - 5 to the left side. Don't forget change the sign of each term when crossing the equal sign. We now have this: 4x^2 -8x + 5 = 0 This is called a quadratic equation. The exponent of 2 gives...
