The answer would be 8.71 because 8.7 is a rounded answer of 8.70
if you add 1 to 70 you would get 71 so the answer is 8.71
Not sure if this is for algebra but this is the algebraic solution.
1. 5x + 1y = 25 (x meaning number of nickels) (y meaning number of pennies)
so 3 solutions could be, 5 nickels and 0 pennies, 4 nickels and 5 pennies, 3 nickels and 10 pennies.
2. First calculate how many days till the end of October, (31-14)= 17 days. then add 30 days for the entire month of November. Then add the 5 days that occurred in December. This will leave you with a total of 52 days.
v = 1
explanation:
-22 + 8v = 7(4v - 6)
distribute 7 into 4v - 6
-22 + 8v = 28v - 42
subtract 8v from both sides
-22 = 20v - 42
add 42 to both sides
20 = 20v
divide by 20 on both sides
1 = v
Zero. That number cannot go into that one
Answer:
Step-by-step explanation:
Let .
Then .
Construct a right triangle.
Make one of the non-right angles .
Recall is equal to the ratio of the side that is opposite to to the side that is adjacent to .
This means opposite side while adjacent side since .
We can find the hypotenuse by using the Pythagorean Theorem.
Take the square root of both sides:
.
Recall is equal to the ratio of the side that is opposite to to the hypotenuse.
-->Because we let the inside equal .
-->Because
