Answer:
IT IS POSITIVE
Step-by-step explanation:
Consecutive integers are one apart from each tother
they are
x,x+1,x+2
sum is -30
x+x+1+x+2=-30
3x+3=-30
minus 3 both sides
3x=-33
divide 3
x=-11
find rest
x+1=-11+1=-10
x+2=-11+2=-9
they are
-9,-10,-11

Answer:
(a), (b), (c) are non-proportional
(d) is proportional
Step-by-step explanation:
An equation or graph with a non-zero y-intercept is non-proportional. That is true for (a), (b), (c).
The table of (d) is proportional, with a constant of proportionality of 6.5.

<em>Comment on (c)</em>
In a proportional relation, price would go up with quantity, not down. If the prices both end in 9, one cannot be double the other, as would be required for the price of a gallon to be proportional to the price of a half-gallon.
Step-by-step explanation:
Let people behind you=x
People ahead of you will be x+2
Total number of people in the line(including you) = x+(x+2)+1 = 2x+3
Also, 2x+3=3x
So x=3
People ahead = x+2 = 5
People behind = x = 3
Answer:
98
Step-by-step explanation:
Of means multiply and is means equals
20% *x = 28
Changing to decimal form
.20 * x = 28
Divide each side by .20
.20x/.20 = 28/.20
x =140
Now we want to find 70% of 140
70% * 140
Changing to decimal form
.70 * 140
=98
