18.87 lbs heavier
Work:
6.29 = apple weight
6.29•4=25.16
25.16 = banana weight
25.16-6.29=18.87
18.87 is the difference between the apples and bananas so therefore is how much heavier the bananas are
We know that the perimeter of a rectangle is 2l+2w
24=2y+2x
Subtract 2x on both sides (we are isolating y)
24-2x=2y
Divide 2 on both sides
Therefore, y=12-x
Some possible values using this equation..
y=8
x=4
Hope this helped :)
You can tell if a line is parallel if they will N E V E R meet (touch, come together ect.)
I believe the answer is 10
Answer:
Step-by-step explanation:
it depends. if (for example) y=x2 then there are an infinite amount of answers. if there is an equation like: If (variable X)= (variable Y) + 5 and if X=5, what is Y? then there is only one answer. check an algebra book, it can give you a more detailed answer.
