4/5÷8/15
multiply by the inverse
4/5 x 15/8 = 60/40 or 3/2 or 1 1/2
Answer:
x = 5.09, -6.09.
Step-by-step explanation:
1/(x-2) - 1/(x+3) = 1/5
Multiply through by the LCM 5(x-2)(x+3):
5(x + 3) - 5(x - 2) = (x - 2)(x + 3)
5x + 15 - 5x + 10 = x^2 + x - 6
x^2 + x - 31 = 0
x = [ -1 +/- sqrt(1 - 1*1*31)] / 2
x = 5.09, -6.09.
Your answer is
a-4a
= 1a-4a
= -3a
85 because 34 divided by 2 is 17 which means hes going 17 an hour. 17 times 5 is 85.
Answer:
-2<x<1
Step-by-step explanation:
-5 < 8x + 11 < 19
Subtract 11 from all sides
-5-11 < 8x + 11-11 < 19-11
-16 < 8x<8
Divide by 8
-16/8 < 8x/8 <8/8
-2<x<1
