Answer:
∠3 and ∠7 ↔ Corresponding Angles
∠2 and ∠7 ↔ Alternate Exterior Angles
∠4 and ∠5 ↔ Alternate Interior Angles
∠3 and ∠6 ↔ Alternate Interior Angles
Answer:
the first number equals 6
the second number equals 10
Step-by-step explanation:
3×n1 + 5×n2 = 68
3×n2 - 4×n1 = 6
3×6 + 5×10= 68
\/ \/
18 + 50= 68
3×10 - 4×6 = 6
\/ \/
30 - 24 = 6
hope this helped :)
Answer:
$173.90
Step-by-step explanation:
The most obvious way to answer this question is to multiply $9.40 by 18.5
This would result in 173.90.
But I realize nobody like to deal with decimals in a multiplication problem, so here's the way I would do it (<em>especially if you don't have a calculator!</em>)
The strategy is to break it down!
Multiply $9.40 x 18 hours to start, since this is easier.

So, that's $169.20 for 18 hours of work.
We aren't finished, because Abdel worked for 18.5 hours.
So, what half of $9.40?

= 4.7
-or-
$4.70
So, knowing that Abdel makes $4.70 in half an hour, lets just add that onto the $169.20 we got earlier.
169.2 + 4.7 = 173.9
-or-
$173.90 for 18.5 hours of work!
Given:
and
where
.
To find:
The explicit formula for the given recursive formula.
Solution:
We know that recursive formula of an AP is:

Where, d is the common difference.
We have,

Here, d=9.
The first term of the AP is
.
The explicit formula for an AP is:

Substituting
and
, we get



Therefore, the required explicit formula for the given sequence is
.
