Let's say that the weight of the orange is x and the weight of the pineapple is y.
The weight of the pineapple is 7 times that of the orange, so
y = 7x.
Also, y = x + 870.
Therefore, 7x = x + 870.
If we take away x from both sides, we get 6x = 870
If we divide both sides by 6, we get x = 145.
Therefore, the weight of the orange is 145 g.
Also, 145 + 870 = 1015.
So the weight of the pineapple is 1015 g.
To convert grams into kilograms, they must be divided by 1000.
Therefore, the weight of the orange in kilograms is 145/1000 = 0.145 kg
And the weight of the pineapple is 1015/1000 = 1.015 kg.
Answers:
a. 145g for the orange and 1015g for the pineapple.
b. 0.145kg for the orange and 1.015kg for the pineapple.
Answer:
y=39
Step-by-step explanation:
Remove the radical by raising each side to the index of the radical.
Answer:
length = x+6
width = x-6
Step-by-step explanation:
The area of rectangle is:
where A is area, l is length and w is width.
We know the area of this rectangle or table since we are given A = x^2-36.
First, substitute A = x^2-36 in.
Then we factor x^2-36, use the difference of two squares:
Compare the terms.
First, we have to understand that length is always longer or greater or have more values than width.
Hence length cannot be x-6 and width cannot be x+6 either.
Thus:
Answer:
no
Step-by-step explanation:
8 is not grater than 9 so it would be 7 6 5 4 3 2 0r 1
Answer:
as it is a square toy
area = l×l
64=l^2
√64=l
8=l
therefore,each side of the toy is 8m long
