If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable.
a = b and c ≠0, then a c = a c . Another example Consider the equation 12 = 12. Divide both sides by 4.
A box shape in three dimensional space. Formally, a polyhedron for which all faces are rectangles.
Rectangule
So, the question is, whether using the ratio of 1.35261 will give the same results as using the ration of 1.35 if the final answer has to be rounded to the hundreth places anyway.
let's try for 10 euros:
10*1.35=13.5 dollars
10*1.35261=13.5261, rounded to 100th: 13.5 the same!!!
Let's try for 250 dollars:
250*1.35=337.5 dollars
250*1.35261=338.1525, rounded to 100th: 338.12
so, if they use the exact exchange rate, they get more dollars!
In fact the more they exchange, the bigger the difference will be ,as for each dollar exchanged the difference is 0.00261.
So they better use the exact exchange rate!
5 hours because if you do 42 divided by 8 you get it so it would be

Answer:
(3x - 5 = -x + 3) x = 2
Step-by-step explanation:
3x - 5 = -x + 3
3x = -x + (3 +5)
3x=-x + 8
(3x + x ) = 8
4x = 8
4/8 =2
x = 2
