Answer:
c = 75
Step-by-step explanation:
Add 6 to both sides: 2/5c = 30
Divide both sides by 2/5 (or multiply by reciprocal of 5/2): c = 150/2
c = 75
All the natural numbers which are not prime numbers are composite numbers as they can be divided by more than two numbers (1 and itself).
Example: factors of 12
12 ÷1 = 12
12÷ 2 = 6
12÷3= 4
12÷4 = 3
12÷6=2
12÷12 = 1
= {12,6,4,3,2,1}
Composite Number/ Its Factors
4 = {1,2,4}
6 = {1,2,3,6}
8 = {1,2,4,8}
9 = {1,3,9}
10 = {1,2,5,10}
12 = {1,2,3,4,6,12}
14 = {1,2,7,14}
15 = {1,3,5,15}
16 = {1,2,4,8,16}
18 = {1,2,3,6,9,18}
20 = {1,2,4,5,10,20}
21 = {1,3,7,21}
22 = {1,2,11,22}
24 = {1,2,3,4,6,8,12,24}
25 = {1,5, 25}

23.
store price = 14 + 0.5(14)
store price = 21
customer price = 21 + 0.08(21)
customer price = 21 + 1.68
customer price = $22.68

formula: A = P(1 + rt)
A = 140(1 + (0.03)(2))
A = 140(1.06)
A = 148.40
interest = 148.40 = 140
interest = $8.40
Hope this helps!! :)
Step-by-step explanation:
due to the rules of crossing lines and their angles, the 2 angles opposite of each other must be equal.
so,
7x + 7 = 112
7x = 105
x = 15
