3 hrs 4.6 mins
Step-by-step explanation:
1/5 + 1/8 = 1/x
x = 40/13
Answer:
B -1/2
Step-by-step explanation:
4x+8y = 11
We need to get the equation in the slope intercept form
y = mx+b where m is the slope and b is the y intercept
Subtract 4x from each side
4x-4x+8y = -4x+11
8y = -4x+11
Divide by 8
8y/8 = -4x/8 +11/8
y = -1/2x +11/8
The slope is -1/2 and the y intercept is 11/8

B) 63
Answer:
x-2x-35
Step-by-step explanation:
-5 and 7
x=-5
x=7
x+5=0
x-7=0
Put them in bracket.
(x+5)(x-7)
Expanding the bracket
x(x-7)+5(x-7)
x-7x+5x-35
x-2x-35
