Answer:
A. Move the decimal point to the left
Step-by-step explanation:
Given that:
The scientific notation = 10⁻¹⁰
Let recall;
That the standard notation usually took the form of an inverse:
For example;
Let say 10⁻¹ will be
in scientific notation;
SO, 
Now; we are given 10⁻¹⁰ as a scientific notation,
To standard notation, we get:

= 0.01
Thus, it is true to say that the decimal point will be moved to the left side when converting a number from scientific notation to standard notation if the power of 10 is -10.
Hey! So this is pretty straightforward. You're given all the information already and now you just have to do some calculations.
60 + 30w = 480
You can start by subtracting 60 from both sides
30w = 420
Now you need to get w by itself so you have to divide both sides by 30 and you will end up getting
w = 14!
It will take him 14 weeks to save up
3x+4=1
3x=-3
x=-1
Hope this helps!!!!
