What are the option? If there are none
then you would take the two fractions and multiply the <span>denominators thus making a new fractions. This is called finding the common denominator.
</span>Ex: 1/2 and 2/3 would have a CD of 6.
<span>So, you would rename them 3/6 and 4/6</span>
Let the width be x, the length is then 3x-10
Area of a rectangle is length times width: x(3x-10)=77 => 3x^2-10x-77=0
Factor this quadratic equation: (x-7)(3x+11)=0 =.x=7 or x=-11/3
width cannot be negative, so the only answer is x=7
width is 7m, length is 11m
In form
ax+by=c
slope=-a/b
a=T
b=12
slopt=-10
-10=-T/12
multiply both sides by 12
-120=-T
mulitply -1
120=t
T=120
The answer is d thx for askin
2.79 / 2 = 1.395 rounds to 1.40 per roll
8.99 / 6 = 1.498 rounds to 1.50 per roll
the better deal (cheapest) is the 2 roll package
** if u want price per roll (price / roll) ...u divide the price by the number of rolls
