Kip starts with 1 4/6 lbs of toffee. First we need to convert this to an improper fraction, the improper fraction is 10/6
Now subtract 5/6 from 10/6,
10/6 - 5/6 = 5/6
Kip has 5/6 lbs of toffee left. He gave half of what he originally had to his friend.
Hope that helps ya!
Answer:
C.
Step-by-step explanation:
Answer:
x = 44 and y = 4
Step-by-step explanation:
Given:
x - y = 40
2x + 3y = 100
Isolate for x in the first equation:
x = 40 + y
Sub x = 40 + y into the second equation and solve for y:
2(40 + y) + 3y = 100
80 + 2y + 3y = 100
5y = 20
y = 4
Sub y = 4 into the equation for x:
x = 40 + 4
x = 44
Therefore, x = 44 and y = 4
Answer:
x(x - 6)(x + 8)
Step-by-step explanation:
First, the GCF of these 3 terms is x.
So to separate x from this it now becomes x(x^2 + 2x - 48).
Now to factor the expression inside the parentheses easily I use "a" and "b" to make it easier.
a + b = 2 (from 2x)
a * b = -48 (from third term of expression)
a = -6, b = 8
Substitute "a" and "b" and I get: x(x - 6)(x + 8)
