Answer:

4.68\times10^9

Step-by-step explanation:

Scientific notation is defined as a way of writing very large or very small numbers.

A number between 1 to 10 is written in scientific notation when it is multiplied by a power of 10.

Here the given scenario is :

A star has a diameter of 4,680,000,000 units.

So, in scientific notation we can write this as :

4.68\times10^9

We can check this if we multiply this by 10^9. This will shift the decimal to 9 places in the right side.

2(a+7) - 7 = 9 what is the answer
REY [17]

Answer:

The answer is 1

Step-by-step explanation:

2(a+7)−7=9

Step 1: Simplify both sides of the equation.

2(a+7)−7=9

(2)(a)+(2)(7)+−7=9(Distribute)

2a+14+−7=9

(2a)+(14+−7)=9(Combine Like Terms)

2a+7=9

2a+7=9

Step 2: Subtract 7 from both sides.

2a+7−7=9−7

2a=2

Step 3: Divide both sides by 2.

2a

2

=
