Answer:
<h2>5</h2>
Step-by-step explanation:
Given the expression (8x² −15x)−(x² −27x) = ax² +bx, we are to determine the value of b-a. Before we determine the vwlue of b-a, we need to first calculate for the value of a and b from the given expression.
On expanding the left hand side of the expression we have;
= (8x² −15x)−(x² −27x)
Open the paranthesis
= 8x² −15x−x²+27x
collect the like terms
= 8x²−x²+27x −15x
= 7x²+12x
Comparing the resulting expression with ax²+bx
7x²+12x = ax²+bx
7x² = ax²
a = 7
Also;
12x = bx
b =12
The value of b - a = 12 - 7
b -a = 5
Hence the value of b-a is equivalent to 5
Answer:
B. 48

Answer:
The answer to your question is: V = 12 + 5n
Step-by-step explanation:
Data
Video games right now = 12
She purchases 5 video games each month
Equation = ?
# of video games in n month = V
Process
- Consider the initial amount of video games
V = 12
- Now, consider the number of video games the buys each month and the months
5n
- Finally, join both terms
V = 12 + 5n
