Answer:
36
Step-by-step explanation:
12 x 3 = 36
With exponents of 10, the exponent really just tells you how many zeroes there are behind the 1. So, for example, 10^4=10000 (4 zeroes behind 1). When multiplying decimals by exponents of 10, you move the decimal to the right, and the amount of places is the exponent number. For example, if I multiply 5.34 by 10^2, I move the decimal over to the right 2 times and get 534.
So, if you just multiply these you get 9.36*10000, which is 93600.

Answer:
Step-by-step explanation:
Let's solve the second equation for x
Now let's replace this in the first equation.
Distribute the 5
Individually solve the fractions.
Solve;
Subtract 20 from both sides.
Divide both sides by -7
Now replace the value of y in any of the two equations to find x.
add 
on both sides.
Multiply by the reciprocal fraction of 3. I suppose you know that 3 is 3/1 hence the inverted fraction would be 1/3
