We have to show 11.63 as a mixed number.
11.63 = 11 + 0.63
0.63 = 63/100
11.63 = 11 63/100
Answer: 11 63/100
-7(2 + n) + 1/3(-9 - 6n)
-14 - 7n -3 - 2n
-17 - 9n
Answer: 6 2/3 or 6.67 pounds per acre (depending on how you write it)
Step-by-step explanation:
40 pounds/ 6 acres
= 6 2/3 or 6.67 pounds per acre
His work should have looked like this.
2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10 When he added in both sides, he subtracted 10 from 10,
5x = 20 instead of adding 10 from 10 to make 20.
x = 4
2(4) + y = 5
8 + y = 5
y = -3
