Answer:
60* and 30*
Step-by-step explanation:
If two angles are complementary then they will add up to be 90, or inversely, if two angles add up to be 90, then they are complementary. If you know one acute angle, you can calculate its complementary angle by subtracting 90 and the angle.

Answer:
$2686.27.
Step-by-step explanation:
The formula for the amount of money after compound interest is
where P is the principal, r is the rate, n is the number of times the interest is compounded per year, and t is the number of years. $1500 is the principal amount of money. 6% in decimal form is 0.06 (divided by 100), so the rate is 0.06. The interest is compounded once per year, so n = 1. And it's after 10 years, so t = 10. So now we can substitute:
Answer:
Tyler's - (-5 - 3y) + (3y) = -5
Han's - (x) + (-5 - x) = -5
Step-by-step explanation:
If we are going to use Tyler's first step then we would use x = - 5 - 3y and substitute it in the original simultaneous equation x + 3y = -5, becoming (-5 - 3y) + (3y) = - 5 giving an exact answer of - 5.
But if we are using Han's first step then we will still substitute into the original simultaneous equation but in 3y. It would become
x + (-5 - x) = - 5 which also gives us an exact answer of -5.
Thus proving that both first steps show the same solution of -5.
