I assume you mean 12 and 4/7.  A whole number is a number without a decimal or fractional part, so you can't do it. But, it CAN be written as a fraction.   First express 12 as 12/1.  Now multiply 7/7 (both numerator and denominator by 7). Note that this doesn't  change...

The y-intercept is the value of y when x=0

let n= one of the integers (the lesser one) then since they are consecutive, the other is (n+1). Now just write the problem as an equation:   n + (n+1) = -105   can you solve it?

There are 2 price changes; the initial price (callit x0) falls to x1, then x1 rises to x2.   Part 1:  x0 falls by 27% to x1, this is the same as saying x1 = (1-.27)*x0 = 0.73*x0           [ You can check this by the definition of fractional change :...

You are given D=distance, V=Speed(also called velocity), and you are asked for T=time. The relationship among these 3 variables is:    D(mi) = V(mi/hr) * T(hr).     You have D and V, you need T.  Using algebra to solve for T: T = D/V   D= 3/4...

let n= one of the integers, then the problem is written as follows; n*(n+1) = n + (n+1) + 5   Expand and combine to form the following quadratic; n^2 -n -6 = 0   Factor;   (n-3)*(n+2) = 0     n= +3, or -2(ignore, need Positive...

Not sure what the question is; can you clarify?
