Answer:
74
Step-by-step explanation:
2x+x+4=115 (ext ∠)
3x=111
x=37
∠MNO=2(37)

Jane was charged $15/4 = $3.75 per item and George was charged
$39/12 = $3.25 per item, so in addition to the charge per item, there must be an extra charge for each purchase.
We note that George bought 12-4 = 8 more items than Jane and was charged
$39 - $15 = $24 more, or $24/8 = $3 more for each additional item. So if we figure $3 per item, we can find out that extra charge.
Jane paid 4 * $3 = $12 for her 4 items, plus $3 to make her total $15.
George paid 12 * $3 = $36 for his 12 items, plus $3 to make his total $39.
So we can see that if x is the number of items, the store charges
x times $3 plus an extra $3.
Using function notation, we write
f(x) = 3x + 3
and then work out the charge for 22 items:
f(22) = 3 * 22 + 3 = 66 + 3 = 69

<em>4</em><em>0</em><em>0</em></h2>
Step-by-step explanation:
12% × ? = 48
? =
48 ÷ 12% =
48 ÷ (12 ÷ 100) =
(100 × 48) ÷ 12 =
4,800 ÷ 12 =
400;
Answer: d
The two smallest sides have to add up to the largest one
So, from the first term, to the fifteen term, there are 14 terms to go through.
that means, if say the common difference is say "d", we have to add "d" 14 times, to get to the 15th term, lemme make a quick table,
and surely you know how much that is.
