Answer:
Step-by-step explanation:
-2/5 - 4/5 + -9/10
= -2/5 - 4/5 - 9/10
= {-2(2) -4(2) - 9)/10
= (-4 - 8 - 9)/10
= -21/10
= -2 1/10
I believe that 30.5 as a fraction is 30 and 1 half but don't take my word
2/3 hour = 20 minutes. so therefore 20 / 5 = 4 x3 = 12
3/5 of that time is 12 minutes.
Answer:
x=5
y=30
x=15
Step-by-step explanation:
y=3x=15, then x=15/3, x=5
x=10, then y=3x=3*10=30
y=3x=45, then x=45/3, x=15
Answer:
4x^2+17x+15
Step-by-step explanation:
(4x-3)(x+5)
= 4x(x+5) -3(x+5)
= 4x^2+ 20x -3x + 15
= 4x^2 + 17x + 15
