416.67 pounds of food should be given all five lions each day
<em><u>Solution:</u></em>
Given that, three adult lions together eat 250 pounds of food a day
Thus, 3 adult lions = 250 pounds of food per day
Two more adult lions joined the group and ate food at the same rate as the original three
Now number of adult lions = 3 adult lions + 2 adult lions = 5 adult lions
Let "x" be the food ate by 5 adult lions
Thus we can say,
3 adult lions = 250 pounds of food per day
5 adult lions = "x" pounds of food per day
This forms a proportion and we can solve the sum by cross multiplying
Thus 416.67 pounds of food should be given all five lions each day
Commutative property: when you have to solve a sum, it does not matter the order in which you place your addends, since you will always get the same result.
We have then:
((40) + (185)) + (240) = 465
(240) + ((40) + (185)) = 465
answer:
Form 1:
((40) + (185)) + (240) = 465
Form 2:
(240) + ((40) + (185)) = 465

There are parentheses, so that means we have to work in them.
There are exponents, so we have to do those first.
[2(49) - 5(7) +4] Exponents.
There is multiplication, that we can do, so we do that left to right.
[98 - 35 + 4] Multiplication.
There is no division.
There is addition and subtraction, so we do those left to right.

Final Answer: 67
To find how many more times more you need to divide the mass of the moon by the mass of Jupiter.
9 x 10^22 / 2 x 10^27
First divide the whole numbers: 9 /2 = 4.5
When you divide exponents subtract them:
22 - 27 = -5
The answer is 4.5 x 10^-5
