Is 83 ft larger than 786 in???
Answers
To convert feet to inches, multiply 83ft by 12 because there are 12 inches in a foot.
83 x 12 = 996
996 in > 786 in
786 in= 65.5 ft
83 ft is larger than 786 in

First, we can start out by finding the greatest common factor (GCF) of the numerator (30) and the denominator (54). To do so, we will list the factors of each number, find the common ones and then the greatest.
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
Factors of 54: 1, 2, 3, 6, 9, 18, 27, 54
Look through both sets of factors. Which are the common factors? 1, 2, 3, and 6 are the common factors of 30 and 54. Now, we have the find the greatest common factor. Basically, which number has greater value out of 1, 2, 3, and 6? The GCF is 6.
Second, our last step is to divide the numerator (30) and denominator (54) by our recently found GCF which was 6. This will create a new fraction which is in simplest form.
Let's collect our new numerator and denominator and rewrite our brand new fraction in its simplest form.

Set up proportions for the problem:
1 pound 4.5 pounds
________ x ___________
16 ounces x ounces
Cross multiply and solve for x.
x= 16 x 4.5
x= 72 ounces
So false, the recipe would call for 72 ounces of rice.
Answer: False
Hope this helps :)

add the 2 equations together
2x+x+y-y=-8-4
3x=-12
divide by 3
x=-4
subsitute
-4-y=-4
addd 4 to both sdies
-y=0
the solution is (x,y) (-4,0) or D
I have decided to use Elimination by Addition.
Add the two equations together
3x = -12
Divide both sides by 3
x = -4
Substitute -4 for x in the second equation.
-4 - y = -4
Add 4 to both sides
-y = 0
y = 0
Check
2(-4) + 0 = -8
-8 = -8 This checks.
-4 - 0 = -4
-4 = -4 This also checks.
The solution set for this system is as follows:
S = {(-4,0)}
That would be option D.
