Answer: x = 2
Step-by-Step Solution:
Given:
OH = WO = LW
OH = 2x + 1
WO = 3x - 1
LW = 5
To Find:
The value of 'x'
Solution:
We know, OH = WO = LW
So, equate any two of the values given :-
2x + 1 = 5
2x = 5 - 1
2x = 4
x = 4/2
x = 2
Hence, x = 2.
0.25x² + 8.5 - 17 = 0
1)
a = 0.25
b = 8.5
c = -17
2)
- 8.5 ± √(8.5)²-4(0.25) (-17)
------------------------------------------
2(0.25)
3)
-34 ± √1428
----------------------
2
4)
-35.894 and 35.894
In 1 hour ther are 60 minute so
1/2 hour=30 minutes
so 30 times 70=resting beats per 1/2 hour=2100
then 150 times 30=jogging beats per minute=4500
subtract
4500-2100=2400
it beat 2400 more times
Answer:
Step-by-step explanation:
-10x+18=10x+4
20x=14
x=14/20=7/10=0.7
