Answer:
x=3
Step-by-step explanation:
- you have to move the terms collect like terms and divide both sides and down load photo math that helps alot with giving answers
X + 60 = 100 (because they are vertical angles, which means that because they are directly opposite of each other, they are of the same measurements).
Solve for x. Isolate the x, subtract 60 from both sides
x + 60 = 100
x + 60 (-60) = 100 (-60)
x = 100 (-60)
x = 40
40° should be your answer
hope this helps
This is a typical radioactive decay problem which uses the general form:
A = A0e^(-kt)
So, in the given equation, A0 = 192 and k = 0.015. We are to find the amount of substance left after t = 55 years. That would be represented by A. The solution is as follows:
A = 192e^(-0.015*55)
<em>A = 84 mg</em>
Answer:
-11.75 - x
Step-by-step explanation:
0.5 squared = 0.25
0.25-12= -11.75
-11.75 - x
It is a composite number and it is written as 7*3*5*2
