Answer:
Do not multiply the coefficients and the exponents. Remember, using the Product Rule add the exponents when the bases are the same.
Do 77 times 14
770+308=1,078
Divide 1,078 by 100
=10.78
Answer:
1 meter = 39.370 inches.....so 5 meters = (5)(39.370) = 196.85 inches
(3, 62)
Since that second equation is equal to y, you can substitute the entire thing into the top equation, getting rid of the y and solving for x. It equals 3.
You can then plug 3 in for x on either equation, which should be 62.
