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

What you can do for this case is to evaluate some points in both functions to realize the behavior:
 x  5x  2x
 -2  -10  -4

given pq = 2x and qr = 4x - 8 and pr = 16. what is the value of x? what is the value of pq? what is the value of qr?
Ugo [173]
Answer:
X= 4
PQ= 8
QR= 8

Explanation:
As shown in the diagram, the line PR is made of the lines PQ and QR. Therefore, we can assume the equation PQ+QR=PR. When using the given values in the problem and substituting them in our equation, it becomes: 2X+4X-8=16 because PQ=2X, QR=4X-8, and PR=16. Here is how x is solved for:
2X+4X-8=16 (Original equation)
6X-8=16 (Simplify by adding 2X and 4X together)
6X=24 (Add 8 to both sides to isolate X)
X=4 (Divide both sides by 6, singling X out)
Referring back to how PQ=2X and QR=4X-8 we can solve for the each now that we know the value of X.
X=4
PQ= 2X= 2*4= 8
QR= 4X-8= 4(4)-8= 16-8=8
Additionally, we can check the answer by seeing if PQ and QR add to make the value of PR, which is given as 16. This proves to be correct as 8+8=16.
**Btw the diagram is not always going to look aligned to the values of the problem. Even though Q is not centered at the midpoint, PQ and QR are equal in value. Diagrams can be deceiving if not specified as to scale!**

What 2 consecutive even integers have a sum of 217?
Mrrafil [7]

Let the 1st number be "2x"
The next consecutive even number is "2x+2"
EQUATION:
2x+2x+2=217
4x+2=217
4x=215
x is not an integer.
WHY?
The sum of two even integers must be even; it cannot be 217.
