You have to use a system. the first would be x + y = 12 since she has 12 coins. the other equation would be 0.05x + 0.1y = 0.95 (an easier way is 5x + 10y = 95 if you clear it). now you just solve using substitution or elimination.
375. 25% of 1500 is 375. You multiply 1500 by .25 to get your answer. When finding percentages of totals, you move the decimal place two places to the right of the percentage and multiply it by the total you need to find the percentage of.
Answer:
a, d and e.
Step-by-step explanation:
A perfect square is one where the coefficient is a perfect square and the exponent is even.
So they are 25x^12, 36x^16 and 9x^8.
1.) y=-M+s
2.) Y=2g+n
Hope this helped :)
Answer:
-39
Step-by-step explanation:
Simplify the following:
36/((-12)/13)
Multiply the numerator of 36/((-12)/13) by the reciprocal of the denominator. 36/((-12)/13) = (36×13)/(-12):
(36×13)/(-12)
The gcd of 36 and -12 is 12, so (36×13)/(-12) = ((12×3) 13)/(12 (-1)) = 12/12×(3×13)/(-1) = (3×13)/(-1):
(3×13)/(-1)
3×13 = 39:
39/(-1)
Multiply numerator and denominator of 39/(-1) by -1:
Answer: -39
