Make x the subject in
Substitute 114 - y for x in
Open bracket
Collect Like Terms
Divide by 3
Answer:
Step-by-step explanation:
This is our absolute function for which we are tasked with finding the values of x that make the whole thing equal 6:
-.5 | 2x + 2 | + 1 = 6. Subtracting 1 from both sides gives us
-.5 | 2x + 2 | = 5. Dividing both sides by -.5 gives us
| 2x + 2 | = -10.
Because absolute value is in fact a distance measure, and one of the 2 things in math that will NEVER be negative is distance, there is no solution to this equation.
7/8 divided by 1/4 (or 2/8) = 3 1/8
C because you have to do 50÷2=25 and 40÷2=20 and 20-25=5
