Answer: 3
Step-by-step explanation: Your equation is p- (-9)=12. A negative plus a negative is a positive. So the equation is basically p+9=12. 12 minus 9 is 3 and that's the answer!
Answer:11
Step-by-step explanation:
Look at middle of pot line
It’s b; both a and b are the basically the same equation so neither one will work and all of them are in standard form so c won’t work
Answer:
x/y = 3/5
=> x = (3/5)y (1)
(x + 8)/(y + 8) = 2/3
=> 3*(x + 8) = 2*(y + 8)
=> 3x + 24 = 2y + 16
=> 3x - 2y = -8 (2)
From (1) and (2), we have:
=> 3*(3/5)y - 2y = -8
=> (-1/5)y = -8
=> y = 40
=> x = (3/5)*y = (3/5)*40 = 24
=> Solution: x = 24, y = 40
Hope this helps!
