3.5(c-8)+c = 12.5
⇒ 3.5c- 3.5*8+ c= 12.5 (distributive property)
⇒ (3.5c+ c) -28= 12.5
⇒ 4.5c= 12.5+ 28
⇒ 4.5c= 40.5
⇒ c= 40.5/ 4.5
⇒ c= 9
The correct answer is 9~
1. To solve this problem, you must keep on mind the followinwg information:
You know that, by definition, an irrational number is a number that cannot be expressed as a fraction.
2. Therefore, the correct answer is the option D.
3. To verify the answer you have:
∛16=2.51
As you can see, the result is 2.51 and the decimal number 2.51 cannot be expressed as a fraction.
2 feet in a second 12 inches in a foot
First solve for parenthesis
73 + 27 = 100
x - 100 = 400
Isolate the x. Add 100 to both sides
x - 100 (+100) = 400 (+100)
x = 400 + 100
x = 500
500 is your answer for x
hope this helps
