Answer:
8x + 4y
here's your solution
=> (10x + 3y) - (2x - 4y)
=>. now multiple - to (2x - 4y)
=> hence we get -2x + 4y
=> now put this in above
=> 10x +3y -2x + 4y
=> solve for common terms
=> 8x + 7y
hope it helps
The answer to your question is 706,000.
Answer:
(x, y) = (-1.4, 1.6)
Step-by-step explanation:
The graph shows the solution pretty clearly. It seems no estimation is required.
Your answer is 3/5b + 79.50 = 132.50.
3/5b +79.50 = what - like an algebra question solve for b.
3/5b +79.50 = -79.50
- 79.50
3/5b = 79.50
5/3 x 3/5 b = 79.50 x 5/3
b - 79.50/1 x 5/3 = 397.50/3
b = 132.50
sqrt(2/3) = 0.816496
since it is a decimal with no repeating numbers it would be irrational
