(2x-10)+(3x-10)=90
(2x+3x)+(-10-10)=90
(5x)+(-20)=90
5x=110
X=22
The first is 34, the second is 56.

First, you need to find the height, in which it says “a height that’s half the length of the longer base side. Can you guess what that is between 7 and 5? It is 7. And you would find half of that which is 3.5. Now you know the height is 3.5. The formula to find a rectangular pyramid's volume is lwh/3 which you would do 7 * 5 * 3.5, which is equal to 122.5, and then you would divide that by 3, which is 40.833 which would round to 40.8, so there is your answer.
It is 40.8 units^3

The required value is 2\times10^9

Step-by-step explanation:

Weight of ants = 4\times10^{-3}

Weight of elephant= 8\times10^6

We need to find, the total weight of about how many ants equals to the weight of an oversized elephant.

The equation given is:

4\times10^{-3} \times a = 8\times10^6

We need to find a:

Solving:

4\times10^{-3} \times a = 8\times10^6\\a=\frac{8\times10^6}{4\times10^{-3}}\\if \,\,10^a/10^-b \,\,then\,\, 10^{a+b}\\a=2\times10^{6+3} \\a=2\times10^9

So, the required value is 2\times10^9
