You move the decimal point 6 places to the right because the exponent is positive.
5.04 x 10^6 in standard form is 5040000.
Answer:
129
Step-by-step explanation:
278 - 149 = 129
For Q3, you can subsitute x = 2 and y = 5 into the systems
-5(2) + 5 = -5
so it's a solution for the first system
-4(2)+2(5) = 2
it's also a solution for the second system
