A + (-7) is the same as a - 7, so you could rewrite it as
a - 7 = -17
+ 7
a = -10
So your answer is a = -10, I hope this helps!
Answer:
52%
Step-by-step explanation:
40% nuts of 5kg = 40% × 5 = 2kg
56% nuts of 15kg = 56% × 15kg = 8.4kg
total of nuts in mixture = 2 + 8.4 = 10.4kg
10.4kg of nuts in 20kg = 10.4/20 = 52%
Answer:
pretty sure it's no solution unless you wrote the equation wrong
Step-by-step explanation:
if you replace y with 0 (to find the roots or zeros) and solve for x then there is not a solution
4/20, 20% chance. The store has 20 puppies. Out of them is 4 poodles. Divide 4 by the total(20). And you get 0.2, remove the decimal place and add it in front of the 0 .02 reverse the numbers 20. Replace the period with a %.
3272 I 2
1636 I 2
818 I 2
409 I 409 so bc. 409 is a prime number has factors of 409 and 1
1 I
so the expanded form of 3272 will be 2^3 *409
