Answer:

300000

Step-by-step explanation:

Do separately

3.6 x 10^8

= 360000000

1.2 x 10^3

= 1200

Then divide them

360000000/1200

=300000

If you want it in scientific notation then it is

3 x 10^5

You have to use the laws of exponents and your knowledge of multiplication by 10.

So we have

We can rewrite like this

So multiplying by the 10 will get read of the decimal

Now divide the 36 by 12 , write one base of 10 subtract and the exponent of 2 from 7

Vinil7 [7]

Ok so
The answer would be the second one (3+3+3+3=3 (4) )
Here's the explanation
It doesn't belong there because all the rest have to do with exponents
And that problem does not
Also,that problem uses repetitive addition while the other ones use repetitive multiplication
Hope this helps :)

After solving the system of equations, x= -3 and y=6

Step-by-step explanation:

We need to solve the following system of equations by substitution.

$-3x + y = 15\,\,\,(1)\\-8x-7y = -18\,\,\,(2)$

Finding value of y from equation(1) and substituting it in equation(2)

$y=15+3x\\substituting\,\,in\,\,equation(2)\\-8x-7(15+3x)=-18\\Solving:\\-8x-105-21x=-18\\-8x-21x=-18+105\\-29x=87\\x=\frac{87}{-29}\\x=-3\\$

The value of x is x=-3

Now, Finding value of x from eq(1) and substituting in equation(2)

$-3x=15-y\\x=\frac{15-y}{-3}\\Substituting\,\,in\,\,equation(2)\\-8(\frac{15-y}{-3})-7y=-18\\\frac{120-8y}{3}-7y=-18\\\frac{120-8y-7y*3}{3}=-18\\\frac{120-8y-21y}{3}=-18\\\frac{120-29y}{3}=-18\\120-29y=-18*3\\120-29y=-54\\-29y=-54-120\\-29y=-174\\y=\frac{-174}{-29}\\y=6$

So, Value of y is y=6

After solving the system of equations, x= -3 and y=6
