To solve this you can make a perportion
252 x
----- = -----
350 100
and solve 252 times 100/350=72
252 is 72% of 350
Answer:
x = 5, -1
Step-by-step explanation:
0 = 3x^2 - 12x - 15 or
3x^2 - 12x - 15 = 0
By solving for x, use the Quadratic Formula.
… x = 5 and/or -1
Answer:
, 12, 
, 10
Step-by-step explanation:
so
= 10
12
= 10.66
and 10
Because saying 5 over 1/2 is saying 5 divided by 1/2 which is the same as saying 5 * 2
8 over 3/4 is 8 divided by 3/4 which is 8 * 1.33.
A fraction is division. If you mean 5 and 1/2 as well as 8 and 3/4 then remove 5 and 1/2 from the answer.
-1 Let's say the set of downs starts at the 20 yard line (maybe the kicking team kicked deep, the receiving team took a knee and so play starts at the 20).
Ok - we're at the 20. First down - they advance 5 yards. So we're now at the 25. We can write that mathematically as:
20
+
5
=
25
So the second play they get sacked deep and lose 6 yards. So we subtract 6:
25
−
6
=
19
So what's the change in yardage for the 2 plays? We are on the 19 and started at the 20, so we can write:
19
−
20
=
−
1
and this makes sense because we know we advanced 5 and fell back 6
