The first thing we should do is turn our mixed number into an improper fraction. To do this, you should multiply the whole number by the denominator, and then add the numerator and place it over the denominator.
Now our problem is 1/3+5/2. Now, we need to find the least common denominator, which is the lowest proportion where these fractions have the same denominator.
Here, we will just multiply the numerator and denominator by 2 and 3, respectively
1/3+5/2 = 2/6+15/6
Now, it is as simple as adding the numerators.
2/6+15/6=17/6
No simplification is needed, so we know this expression is equal to 17/6 or 2 5/6.
-2b + 7 > 27.5
- 2b > 27.5 - 7
- 2b > 20.5
b < - 10.25

Answer:
Step-by-step explanation:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable.
Given that y varies directly with x, if we introduce a constant of proportionality, k, the expression becomes
y = kx
If y = 8 when x = 3, then
8 = 3k
k = 3/8
Therefore, the direct variation equation that relates x and y is
y = 3x/8
When x = 12, then
y = 3 × 12/8
y = 4.5
Part A: 2x-3=5
Part B: Bob the 4 brand new CDs.
Step-by-step explanation:
Given,
Number of CDs Ann has = 5
Number of CDs Bob has = x
Ann has 3 less CDs than twice the number of Bob's CDs.
Number of Ann's CDs = 2x - 3
Part A: Translate the situation into an algebraic equation:
2x-3=5
Part B: For the correct equation, find the value of x (the number of brand new CD'd Bob has).
Dividing both sides by 2;
Bob the 4 brand new CDs.
