Since there are 60 minutes in an hour, 35 minutes is the same as 35/60 hour.
35/60 reduces to 7/12.
35 minutes = 7/12 hour
4(1+1+2)-2(1)+8+4 you would just plug it in for x and y. And then solve the equation.
Answer:
{-14, 4}
Step-by-step explanation:
the absolute value function only makes sure that the result always has a positive sign.
so, (x + 5) must be either +9 or -9 to make the original equation true. the absolute value would turn both into +9.
so,
x + 5 = 9
x = 4
and
x + 5 = -9
x = -14
that gives us the correct set of solutions as indicated above.
