5.
aritmetic is same increase per term
14 to 21 is 7
21 to 42 is 21
7≠21
no
6.
decreases by 4 each time
an=a1+d(n-1)
an=10-4(n-1)
n=12 for 12th term
a12=10-4(12-1)
a12=10-4(11)
a12=10-44
a12=-34
it is -34
7.
missing term is y
22+n=y
y+n=34
22+n+n=34
22+2n=34
minus 22 from both sides
2n=12
divide both sides by 2
n=6
22+n=y
22+6=y
28=y
28 is answer
5. no
6. -34
7. 28
121.5
121.5 rounded to nearest whole number is 122 --> 121.49 rounded to the nearest whole number is 121
$55. Multiply 15 by 20 to find out exactly how much he needs for 20 weeks, which is $300. subtract 245 from 300 to find out how much more money he needs to add to his account.
Answer: $12,000
Step-by-step explanation:
Miguel makes 6% on every sale he makes and wants to make $600 in commissions.
The amount he needs to sell is therefore the amount that has $600 as 5% of it.
Assume the amount of insurance needed is x.
x * 5% = 600
x = 600 / 5%
x = $12,000
