Answer:
40 + 4.5v ≥ 145
Step-by-step explanation:
Let n = the unknown number.
Six times a number = 6 * n = 6n
20 more than number = n + 20
Greater than = >
Put it all together:
6n > n + 20
Subtract n from both sides to get constants on one side and variables on the other:
6n - n > 20
5n > 20
Divide both sides by 5 to isolate variable N
n > 4
or (4, ∞)
Answer:
0.954
Step-by-step explanation: 1 KG is 1,000 grams. So, if his geography book is 954 grams, it’s less than 1,000, so it would be a decimal, as 0.954.
Round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
This will be 790
