3 (4x + 6) = 21
4x + 6 = 21/3
4x + 6 = 7
4x = 7 - 6
4x = 1
x = 1/4
Answer:
C. 5.2 cm
Step-by-step explanation:
Arc length formula:

where s = arc length
n = central angle of arc
r = radius of circle
diamter = d = 10 cm
r = d/2 = 10 cm/2 = 5 cm
n = 60 deg



Answer: 5.2 cm
The inequality would be 3.1h + 2.3b ≥100
Step-by-step explanation:
Earning of Tammy for each hour of work= $3.1
Total hours she worked= h
Earning for picking each bushel of apple= $2.3
Total bushel she picks= b
Her goal = minimum of $100
Hence total earning from working= earning from each hour* no of hours worked
Total earning= 3.1h
Similarly, total earning from picking up apple bushels= earning from picking one bushel*no of bushels picked
Total earning= 2.3b
According to question total earning must be greater than $100
Hence, 3.1h + 2.3b ≥100
Answer:
e total number of minutes, m.
Step-by-step explanation:
The dependent variable is the variable in which the variable cannot stand by itself.
In this situation, the total number of minutes, m, equal 20 times the number of d.
m = 20d
d, is a variable which can be multiplied which states that it has a value, no matter what. On the other hand, m, requires d, to be there in order to have a value.
The answer is, m, the total number of minutes.
