First find the formula which is A(N)=A+(N-1)D then fill in what you know
N=term your looking for
A=first term
D= common diffrence
Once filled in you will get this 18(18)=18+(18-1)-6
then solve to get 324= -84
Your final answer is that the 18th term is -84
Hope I could help
36 pounds because there’s already 36 pounds in the tire and there needs to be 72
Supplementary, and if they have a sum of 90 they are complementary.
ANSWER
Rewrite and make substitution.
EXPLANATION
Since Harriet calculated 27 divided 4 and had 6.75.
This means that:
Now we want to find
without divide.
Therefore we need to rewrite the expression so in terms of
so that we can substitute.
This will give us;
This implies that,
Look carefully at the point where the 2 lines intersect. From that point, look straight down to the x-axis; you'll see that the x-value there is 50. Similarly,
starting at the intersection, look straight left to the y-axis; the y-value there is 11.
Thus, the coordinates of the intersection (i. e., the solution) are found in (50,11).
