Answer:
1+b/a
Step-by-step explanation:
To find the amount of a/b we have to solve the equation
(a+b)/a
a/a+b/a
a/a is one so
1+b/a
I think x=90°, and z=136°
Answer: ok
Explanation: doesn’t need anything
The correct answer is Choice A.
This is an example of an exponential equation, so we need the formula

.
The a value is the starting value of 100. The b value must be a decimal lower than 1 because it is decreases.
If you substitute in 8 for x, you will see that the output is about 50 (half of 100).
