Answer:
because it is 3/4 of the entire bag, there has to be a Ratio:
3:4 = 4.5:w
\frac{3}{4} \frac{4.5}{w}
cross mult.
3w= 4.5(4)
3w = 18
divide 3 both sided
18/3=6
w=6
6lbs of food.
Therefore, your ans is 6lbs of dog food
Step-by-step explanation:
8z=4(2z+1)
First you would distribute the constant into the numbers in the parentheses. so
8z=8z+4
then you would combine like terms which in this case would result in a zero.
8z-8z=0 So the z would be zero or no solution.
Divide both sides by 2
p + 1 = 16/2
Simplify 16/2 to 8
p + 1 = 8
Subtract 1 from both sides
p = 8 - 1
Simplify 8 - 1 to 7
<u>p = 7</u>
