Answer:
Example 11 answer = 12
Step-by-step explanation:
40, 36, 32, 28
is an arithmetic sequence.
The first term (a) is 40
The common difference (d) is -4
The formula for finding the nth term (
in an arithmetic sequence is;
= a + d(n - 1)
= 40 + -4(8 - 1)
= 40 - 28 = 12
You got divide só see mean, the middle number is the median, range you add all number and divide but how many number has
90
55+65=120
there are 3 numbers and when you divide them it makes 70.
70 x 3 = 210
210 - 120 = 90
55 + 65 + 90 = 210
210 / 3 = 70
the sum of the lengths of any two sides of a triangle is always greater than the length of the third side
T=the third side
12+18>T
12+T>18
18+T>12
the first equation says that T<30
the second equation says that T>6
putting these together...
6<T<30
Answer:
pervious prices is $4.8 per pound
Step-by-step explanation:
current price is $6 per pound
previous price is 20% less than current price
20% of 6
6 × 20 ÷ 100 = $1.2
$6 - $1.2 = $4.8
