Answer:
$0.69 for each bag
Step-by-step explanation:
Since you have 12 bags for $8.25, that means you need to divide the price by the number of bags to get the price of each:
You then need to round to the nearest hundredths. Since the number after the hundredths place is a 7, which is greater than or equal to 5, you need to add 1 to the hundredths place making the final answer $0.69
Answer: 105 kilometers
Step-by-step explanation:
1 kilometer=1,000 meters
15,000 (meters a day) x 7 (days a week) = 105,000 meters.
Convert the meters to kilometers:
105,000/1,000 = 105 kilometers
Answer:
Your answer is 65
Step-by-step explanation:
f(x) = x² - 4x - 12
f(-7) = (-7)² - 4 x (-7) - 12
= 49 - (-28) - 12
= 49 + 28 - 12
= 77 - 12
= <u>65</u>
-15 is the smaller number because the further you go into the negatives like -30, -47, -52; youre getting further away from 0 and after 0 are positive numbers so -15 would be the smaller number
{x+2y+2z=0
{2x+y+z=3
{x-3y-z=1
{x+2y+2z=0
-
{4x+2y+2z=6
{-3x=-6 → x=2
{-3y-z=-1
+
{y+z=-1
{-2y=-2 → y=1
{2+2+2z=0 → 2z=-4 → z=-2
Final triple is
(2; 1; -2)
