One way to solve:
960-12x=816
144=12x
12=x
Another way to solve
80-x=68
x=12
Answer:
4
Step-by-step explanation:
Q*1/5-t
Q=k/5-t
8=k/5-3
8=k/2
8x2=16
k=16
Q=16/5-t
16=16/5-t
16(5-t)=16
80-16t=16
80-16=16t
64/16=t
t=4
Refer the attached figure of the graph (Option A) that shows the solution to the given equation
<u>Step-by-step explanation:</u>
The given logarithmic equation is

The solution to this logarithmic equation is where the graph of

When comparing above with the given equation, we find that y = 1.
Now, find the 'x' value by using this. So, applying log base 3 rule on right side, we get as below,

x = 3 - 2 = 1
Plot the asymptote and the point (1 , 1). Sketch the log curve using those two reference facts. Hence, concluded the graph in option A as solution to the given equation.
To get our answer, can either work backwards, or use another viable strategy, giving random operations until we find the correct answer.
40/10/4*(8/2-3)*5^2 = 25
The second problem is much simpler. There is no exponent in this problem, therefore making it much easier to complete.
(9+5)+2+4+30-2+3 = 51
Hope this helps. :)
