X - ( 1 / 2 )x - ( 1 / 3)x = 6x / 6 - 3x / 6 - 2x / 6 = ( 1 / 6 )x, where x is full tank of gas
The answer is 1 / 6 of the gas have left ;
Answer:
33(5/6) sq miles
Step-by-step explanation:
Area = LxW
812 = 24xW
Divide by 24
W = 33.8333333 ( 33 (5/6)
8 is non repeating
3 is repeating
For nominator subtract the non repeating (83-8 = 75)
For denominator : one 9 for each non repeating,one zero for each repeating (only 3 is repeating,then one zero)
75/90 = 5/6
Answer:
1. x = ±9
2.
3. 12 and -12.
4. Antoine is incorrect. There exists two solutions x=5 and x= -5.
Step-by-step explanation:
According to the questions,
Problem 1.
i.e.
i.e. x = ±9.
Problem 2.
i.e.
i.e.
i.e.
Problem 3. [tex]f(x)=x^{2}-144[tex]
To find the roots, we take, [tex]x^{2}-144=0[tex] i.e. [tex]x^{2}=144[tex] i.e. x = ±12.
Thus, the options are 12 and -12.
Problem 4. We have [tex]f(x)=x^{2}+25[tex]
For the roots, we take, [tex]x^{2}+25=0[tex] i.e. [tex]x^{2}=25[tex] i.e. x = ±5.
Thus, Antoine is not correct and two solutions namely x=5 and x= -5 exists.
Now we have to,
find the required value of x.
Let's begin,
→ 3x-2 = 2(x-5)
→ 3x-2 = 2x-10
→ 3x-2x = -10+2
→ x = -8
Hence, value of x is -8.
