Sarah is 8, Ricky is 13 age now age 3 yrs ago Sara x x - 3 ricky x + 5 (x+5)-3 so (x+5-3)= 2*(x-3) x+2=2x-6 x=8

no solutions, or empty set solve both equations for y: y >= -1.5x + 20 y <= -1.5x + 42.5 Same slope with different y-intercepts indicates parallel lines; Graph both, which shows the solution set: solutions for 1st equation are above the line, and solutions for 2nd equati...

where's the rest of the problem?
math
Do you know how to use parentheses? I don't know if I should read your problem as written or how I think you intended it to be written. Ex: 5x divided by (x-2) would be written as: 5x/(x-2), not 5x/x-2.
math
It's not clear what you are asking. If you are dividing 2 by quantity [(1-x)*(1+x)], then your answer is sqrt3/3; where x does not equal 1 or -1 (that would induce division by 0).
