Multiply the amount of shoes being bought (7) by the price of one pair of shoes (15):

7(15) = $105 with NO discount

If you have 10% off that means that you will be paying 90%. Multiply 90% or 0.9 by the cost of the seven shoes:

0.9(105) = 94.50

You will pay $94.50 for the seven pairs of shoes.

When dividing with polynomials, the goal is to determine how many times the dividend divides evenly into the?
kkurt [141]
Whether dividing constant terms or polynomials, we always have definitive terms when it comes to division. Suppose we say, 10x divided by 2. The dividend is the 10x and the divisor is the 2. In other words, the dividend is the number to be divided by the divisor, to obtain the answer called the quotient.

When dividing polynomials, your main goal is to be able to divide the dividend evenly into the <em>divisor</em>. For example, we divide x²+2x+1 by x+1. The first thing you're going to focus is, what term will completely divide the first term of the polynomial? That would be x. Why? Because when you multiply x with x+1, the product is x²+x. When you subtract this from the polynomial, the x² will cancel out. All you have to do is subtract x from 2x, yielding x. Then, you carry down the last term of the equation: +1. You do the steps again. The term that will completely divide x+1 by x+1 is 1. When you subtract the two, you will come up with zero. That means there is no remainder. The polynomial is divisible by the divisor. 
                          x + 1
                        ------------------------------------
                  x+1| x²+2x+1
                        - x²+x
                         ----------------------
                                 x +1
                               - x + 
                             ------------

Formula One race cars can reach speeds of approximately 100 meters per second. What is this speed in meters per minute?
WARRIOR [948]
Set up multiplication/division of ratios to cancel out units you don't need for the final answer and introduce those that you do.

We have m/s and we want m/min so

(100m/s)(60s/min)=6000m/min
