You need to establish the 2 equations first: Let x = the price of the apples and let y = the price of the peaches 3x + 2y = $3.00 4x + y = $2.75 Solve for one of the unknowns (I'd pick the bottom) and then substitute it in the other equation...

Area of a rectangle is written as A = L * W We know the length is x We know the width is (x + 3) Plug both into the equation above. A = (x)(x+3) Simplify A = x2 + 3x === Equation for Area We...
Chain rule: (2x^2-7)^4 = f (as per you stating this is how it should be written) Follow the steps for power rule, but now you'll have to differentiate what is inside the parenthesis. Technically you have done this with say x^2, which is 2x * 1 (derivative of x is 1) 4*(2x^2-7)^3...

The ratio means the number of students to every teacher, meaning for 1 teacher there are 30 students.
Acetate = CH3COO- Platinum = Pt+2 Pt(CH3COO)2 Acetate has a a minus -1 charge, and platinum has a +2. I need 2 acetate atoms to balance out the charge on the platinum. Does that make sense? Hope this helps.
Problem: 12a4b - 7a2b2 + 8ab3 -6a4b - 5a2b2 + 3ab3 Answer: We want to look at those terms that have the same variable and exponent. They need to match. Let's make first put these in order, bunching all the like terms. 12a4b - 6a4b + 8ab3 +...
