−1
Explanation:
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:
+5 −6 = −1

adding 3.24 x and 8.37x on the right side:


adding 8.09 to both sides:



dividing both sides by 11.61
Answer : x=1.37
Short Answer: B
Remark
The area of any triangle is
A = 1/2 b * h
b = 7 3/4
h = 4 2/3
Step one
Convert all fractions to improper fractions.
7 3/4 = (28 + 3) / 4 = 31/ 4
4 2/3 = (12 + 2) / 3 = 14/3 Now multiply
Step Two
Multiply
Area = 1/2 * 31/4 * 14/3 Multiply the numerators together and then the denominators.
Area = (1 * 31 * 14) / (2 * 4 * 3) = 434 /24
Step 3
Convert this to a whole number + a fraction
Area = 18 + 0.08333333 You already have your answer. It is B because only B gives an answer of 18. But you can get the rest of
Let x = 0.083333333
100 x = 8.3333333333
<u>x = 0.0833333333 </u> Subtract
99 x = 8.25 Divide by 3 on both sides.
33 x = 2.75 Divide by 11
3x = 0.25
x = 0.25/3 Multiply top and bottom by 4
x = 1 / 12
The answer is 18 1/12.
