Kevin must have 3x-2 ......so these are the two eqns
Answer:
t=-10 or t=20
Step-by-step explanation:
We want to solve the equation:
We use the definition of the absolute value function to get:
Divide through the first equation by -1 to get:
We now add 15 to both sides of the equation to get:
Divide through by 3
<span>adjacent means close too</span>
Answer: 2n-8
Explanation: 2(n-6)+4 you bring 2 into the parentheses so 2 x n is just 2n
then 2 x -6 = -12
New equation 2n-12 +4
Now you combine-12 and 4 which is -8
Finale equation: 2n-8
1/12c = 0.6
To remove a fraction you simply multiply it by its inverse fraction (take the original fraction and flip it! So, multiply it by 12/1 (which is the same as saying 12).
12(1/12c) = 0.6*12
The 12 cancels out leaving this:
c = 0.6 * 12
c = 7.2
If you don't have or are allowed to use a calculator. To compute that you simply make 0.6 into a fraction then multiply the numerator by 12. .6 is in the tenths place so you can write it like this:
6/10 simplifying it becomes, 3/5
3/5 * 12 = 36/5
Now! That was assuming 1/12c was written like this:
(1/12)c = 0.6
If it was actually written like this:
1/(12c) = 0.6 then you'll do this.
Multiply 0.6 by 12c. Which will get you 7.2c. After that you need to get c alone, so you divide both sides by 7.2. Yielding the result:
1/7.2 = c
c = 0.1389...
