while excluding 0, the product and quotient is positive if operating between same sign, otherwise if we operating different sign will resulted negative.
Answer:
A
Step-by-step explanation:
1/2(2/3y) - 1/3y = 5
1/3y - 1/3y = 5
0 ≠ 5

Answer:
x = (74-28)/2
Step-by-step explanation:
We find the perimeter of a triangle by adding the sides together
s1 +s2+s3 = P
The perimeter is 74
s1 +s2+s3 = 74
We know one of the sides is 28
28 +s2+s3 = 74
The other two sides are equal in length, call them x
28 +x+x = 74
Combine like terms
28+2x = 74
We want to solve for x
Subtract 28 from each side
28-28+2x = 74-28
2x = 74-28
Divide each side by 2
2x/2 = (74-28)/2
x = (74-28)/2
Answer:
First differences means take the ordered pairs in increasing order for their x coordinates (assuming the x's go by ones), then subtract each y (except the last) from the y that comes after it. Keep doing that and you get the first differences. (The second differences would be what you get if you then subtract each of the first differences from the one that came after it (TMI probably but ...)
Say the points were (1,3), (2,7), (3,11) and (4,15). The first differences are
7-3 = 4
11-7 = 4
15 - 11 = 4 all 4. This would also be the slope. So that is the relationship - they are the same.
On the 21st day, he sprints 205 yards.
Is that what you meant for the problem
or do u want to know how many yards he sprinted total for the 21 days
If it is,
he sprinted a total of 3390 yards
