Answer:
x < 1
Step-by-step explanation:
x+9<10
Subtract 9 from each side
x+9-9<10-9
x < 1
Donald can feed 61 animals approximately
<em><u>Solution:</u></em>
Given that Donald has pounds of grain to feed his farm animals
Each animal eats of a pound of feed
<em><u>To find: number of animals he can feed</u></em>
From given information,
Total pounds of grains =
One animal feeds =
number of animals he can feed = Total pounds of grains divided by one animal feeds
Thus he can feed 61 animals approximately
Answer:
<u>The correct answer is A. x = 6 + 3 √10</u>
Step-by-step explanation:
Let's solve for x:
x² - 12x + 36 = 90
Factoring this quadratic equation, we have:
(x - 6) (x - 6) = 90
(x - 6)² = 90
x - 6 = √90 (Square root to both sides of the equation)
x = 6 + √90 (Adding 6 to both sides of the equation)
x = 6 + √9 * 10
x = 6 + √3² * 10
x = 6 + 3 √10
<u>The correct answer is A. x = 6 + 3 √10</u>
