So we start by getting x on one side of the equals sign
2x-14=10
+14 +14
2x=24
divide them both by 2 to get x by itself
x=12
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~
To compare fractions you need a common denominator, then you can make a
comparison. You would divide the number line between 0 and 1 (or any 2
whole numbers on the number line) based on that common denominator. For
example... if you were trying to compare 3/4 and 2/8, you would find
the common denominator (in this case 8) and convert the fractions...
3/4 = 6/8
2/8 stays as 2/8
Now
you would go to the number line between 0 and 1 and divide it into 8
equal pieces. 3/4 would go over the 6th division and 2/8 would go over
the second division.
That would give you a good visual that 2/8 < 3/4
[ / / / / / / / ]
0 2/8 3/4 1
