1m = 100cm therefore 1cm = 0.01m
347 cm = 347 · 0.01 m = 3.47 m
2 1/2 becomes 2 2/4. 3 1/4-2 2/4 = 3/4 of an hour
Older people can afford more pets than younger people... right?
This is a true statement. Here's how we know. The factors of that general formula are (ax - b)(ax - b). If that is in fact the general formula of the quadratic shown, then our a would be 2 and our b would be 3, since 2 times 2 is 4 which is the leading coefficient, and 3 times 3 is 9 which is the constant. Those factors, filled in accordingly, would be (2x - 3)(2x - 3). If we FOIL those out we should get back the quadratic in question. FOILing gives us

which of course simplifies to

<span>We simplify the equation to the form, which is simple to understand
<span>q+2/5=2q-11/7
Simplifying:
<span>q + 0.4=2q-11/7
Simplifying:
<span>q + 0.4=2q-1.57142857143
We move all terms containing q to the left and all other terms to the right.
<span>+1q-2q=-1.57142857143-0.4
We simplify left and right side of the equation.
<span>-1q=-1.97142857143
We divide both sides of the equation by -1 to get q.
<span>q=1.97142857143</span></span></span></span></span></span></span>
