Software was 1/(1+4) = 1/5 of the total amount, so was $800.
Step-by-step explanation:
= - 4
= a* + (3- 1) d*
- 4 = a + 2d . . . . . . . . .(i)
= - 29
= a + ( 8 - 1) d
- 29 = a + 7d . . . . . . . . (ii)
subtracting equations (i) and (ii)
25 = 5d
d = -5
placing d = -5 in equation (i)
a - 10 = -4
a = 6
For an arithmetic Progtession
= a + (n - 1)d
= 6 + (n- 1)-5
= 6 - 5n + 5

Answer:
Yes
Step-by-step explanation:
They add up to 90 degrees.
Answer:
u = 1/6
Step-by-step explanation:
<u>1</u> (12u - 2 )= 0
3
3×<u>1</u> (12u-2) =0×3
3
12u -2 =0
<u>12u</u> = <u>2</u>
12 12
u = <u>1</u>

You already have the answer. It is "One type of proof is a two-column proof. It contains statements and reasons in columns. Another type is a paragraph proof, in which statements and reasons are written in words. A third type is a flowchart proof, which uses a diagram to show the steps of a proof." which looks correct to me.
