40 if you truly really think about it
To find S or T add them together:
3/5 + 1/3
Rewrite the fractions to have a common denominator
9/15 + 5/15 = 14/15
Answer: 14/15
8.45 = 8 45/100 = 8 9/20 = 169/20
A. 8 3/8 = 67/8
B. 8 4/9 = 76/9
C. 8 3/5 = 43/5
D. 8 5/12 = 101/12
The common denominator of all those fractions is 360, so we can write them as:
8.45 = 3042/360
A. 8 3/8 = 3015/360
B. 8 4/9 = 3040/360
C. 8 3/5 = 3096/360
D. 8 5/12 = 3030/360
As a mixed numbers:
8.45 = 8 162/360
A. 8 3/8 = 8 135/360
B. 8 4/9 = 8 160/360
C. 8 3/5 = 8 216/360
D. 8 5/12 = 8 150/360
Now we can easily see that only 8 216/360 is greater than 8 162/360. It means the correct answer is C: From the given mixed numbers, only 8 3/5 is greater than 8.45.
If you're looking for equivalents to 3^x, choices
... D. (15^x)/(5^x)
... E. (15/5)^x
... F. 3×3^(x-1)
are the only ones that qualify.
y=2/3y-3
1. y = 2/3 (9)-3 multiply 9 and 2 =18/3
y=18/3-3 divide 18 and 3 =6
y=6-3 subt. 3
y=3
2. -11=2/3x - 3
-11+3 = 2/3 x add 3 to both sides to cancel -3
-8=2/3 x
(3/2)-8 = (2/3)3/2 x multiply both sides by reciprical of 2/3
-24/2 = x divide
-12=x
