Answer:
It has 5 significant figures.
Step-by-step explanation:
If Simone has 20 bills, then:
1/5 of 20 = 4 [hundreds]
1/4 of 20 = 5 [fifites]
1/10 of 20 = 2 [$20s]
4 * 100 + 5 * 50 + 2 * 20 = 400 + 250 + 40 = 690 [out of $780]
4 + 5 + 2 = 11 [out of 20 bills]
So now we can easily find out she had 9 bills of tens - because 20 - 11 = 9 or because (780 - 690) ÷ 10 = 90 ÷ 10 = 9.
Answer:
The answer is 5 + 3x ≤ 50
Step-by-step explanation:
5 + 3x ≤ 50 - 5
3x ≤ 45
Divide by 3, x = 15
This is the commutative property of addition. It basically says, x+y=y+x.
