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

3 times what equal 19?
MissTica

Answer:

6 1/3

Step-by-step explanation:

3 times what equals 19 can be in the form of an equation as shown below. It shows that the value we are finding for is unknown, therefore it is a variable. A variable is the unknown value in an equation.

Equation: 3x = 19

With the equation in hand, we can now solve the problem easily.

3x = 19

Carry the 3 to the 19(Carry over the like terms across leaving the variable or the unknown)

x = 19÷3

x = 6.33333 or 6 1/3

To check if the answer was correct:

3 × 6 1/3 = 19

You regain the answer <em>19</em>
