In order to solve first convert both values into improper fractions:
18/5+63/10
second, convert both values to fractions with a base of ten:
36/10+63/10
finally, add the numerators:
99/10 is the final answer
D.
204 is how much she had at the end of the month so you want to take away both deposits to find out how much she had at the beginning of the month.
These numbers are "a" and "b".
Sum is 64, so
a+b=64
Difference is 42 so
a-b=42
So you've got:

When a+b=64 and a=53 you've got:
53+b=64
b=11
So these numbers is 53 and 11.
Given:
The dotted boundary line passes through the points (-3,-8), (1,-2) and (9,10).
Above line is shaded.
To find:
The inequality for the given graph.
Solution:
Consider any two points on the line. Let the two points are (1,-2) and (9,10). So, the equation of the line is:





Multiply both sides by 2.




Above line is shaded and the boundary line is a dotted line. So, the sign of inequality must be >.

This inequality is not in the equations. So, multiply both sides by -1 and change the inequality sign.


Therefore, the correct option is D.
