Take water heating up for example. Heat travels just from...heat!
Answer: x = 13
Step-by-step explanation: When solving an equation like this, we are trying to get our variable which is our letter by itself.
So we first want to ask ourselves what is the 14 doing to <em>x</em>. Well, we can see that it's being added to <em>x</em> so to get <em>x</em> by itself, we will do the opposite of addition which is subtraction. So we subtract 14 from both sides of the equation.
The +14 -14 cancels out so we're left with <em>x</em> on the left.
On the right, we must subtract 14 from 27 to get 13.
So we have x = 13 which is the solution to this equation.
Answer:
A) 1:2
B) 3:5
C) 5:4
D) 17:5
Step-by-step explanation:
Step 1) Convert the decimal number to a fraction
Step 2) Multiply the numerator and denominator by 10 to eliminate the decimal point.
Step 3) Simplify the fraction in the previous step by dividing the numerator and the denominator by the greatest common factor (GCF)
Step 4) Convert the fraction in the previous step to a ratio by replacing the divider line with a colon
Heres an example. I'll do the last one.
3.4 = 3.4/1
(3.4 x10) /(1 x 10)= 34/10
34 /2 = 17
10/2 = 5
17/5 = 17:5
