Answer:
Canada was 418.912 sq miles smaller than the USSR.
Step-by-step explanation:
Note: I don't know if this question required a calculator so I'll answer without one.
Symbols:
- USSR area in sq miles = u
- Canada area in square miles = c
u<em> </em>= 8.649×106
c<em> </em>= 4.797×106
x = how much less area
u<em> </em>= c + x
- USSR area = Canada area + number of sq miles less
Math:
u = c + x
8.649×106 = 4.797×106 + x
- divide by 106 to get rid of the ridiculously large numbers.
8.649 = 4.797 + 
- subtract (use calculator or just traditional subtraction methods)
3.952 = 
- multiply both sides by 106 (use calculator or traditional methods)
418.912 = x
What’s c? Not valid question
The answer is -6.825 in fraction form, it would be -6 33/40
Answer:
16/y = x
Step-by-step explanation:
You cannot solve for the question yet. However, you can create an equation!
we know that each person paid 16 dollars.
We don’t know how much the bill was or how many people were there.
So out equation looks like;
z/y = x
or
z * x = y
z = how much each person paid.
y = how much each person paid.
x = how many people paid.
Substitute with what we know.
16/y = x
16 * x = y
Now you will be able to substitute for either x or y to find either answer.
