Step-by-step explanation:
taking that blank as x
5/2 -x = 1/3
the x will go to the right hand side of the equation which then would make it positive ( making x the subject) and 1/3 will come to the left hand side of the equation becoming -1/3
so the equation will become 5/2-1/3=x
solving the fraction then gives 13/6 or 2.17 as the value of x
Answer: number 4 the last option
Step-by-step explanation: too lazy to write it out.... 0-0
Answer: C
Explanation:
Sqrt(3)/2 is only positive in the first and second quadrant.
x = -1/2 or x = 1/2, but there is no option for -1/2 so it must be 1/2.
Colleen says she is thinking of a 4 digit number in which all the digits are the same.
Since, the value of the digit in the hundreds place is 200. It means that one of the digit of the given number is 2.
Since, all the digits of a number are same.
Therefore, the number is 2222.
Now, we can expand 2222 = 2000+ 200 + 20 + 2
Hence, we can observe the relationship between the digits of the number that the number 2222 is expressed as the sum of the place value of each of the digit.
