You make use of the given relationships to write an equation only involving "a".
... a = (sum of three numbers) × (1 + 0.25) . . . . a is 25% more than the sum of three numbers.
Then
... (sum of three numbers) = a/1.25 = 0.8a
The sum of the three numbers and a is given as 783.
... sum of 4 numbers = (sum of three numbers) + a
... 783 = 0.8a + a = 1.8a
... 783/1.8 = a = 435
The appropriate selection is (B) 435.
Answer:
10:30
Step-by-step explanation:
Half an hour is 30 min
Estimate : 14 - 2 = 12......20 - 12 = 8
real thing :
13.59 - 1.85 = 11.74
20 - 11.74 = 8.26
5x^3=1,080
1. Divide both sides by 5.
x^3=216
2. Write 216 in exponential form.
x^3=6^3
3. Root.
x=6
Solution: x=6
