Answer:
Resulting expression is - 0.8x + 4.8y +16.
Step-by-step explanation:
Given : 4(0.5x+2.5y-0.7x-1.3y+4).
To find : what is the resulting expression.
Solution : We have given that 4(0.5x+2.5y-0.7x-1.3y+4).
First we will solve the parenthesis by combine like terms:
4( 0.5x - 0.7x +2.5y -1.3y +4).
4( - 0.2x + 1.2y +4).
Now distributes 4 over parenthesis's terms
- 0.8x + 4.8y +16
Therefore, Resulting expression is - 0.8x + 4.8y +16.
Not 100% sure but i will say (B)
A
look where the plot is Set 1 is at 8 and Set 2 is at 10. obviously 10 is greater than 8
Multiply both sides by 3
The correct answer is actually around 21%. Are you sure the question wasn't asking what the approximate percent decrease from 85 to 70 was? Because in that case it would be around 17%.
