Answer:
B
Step-by-step explanation:
the question says -12x ≤ -72.the sign ≤ means less than or equal to. so we will divide both sides by -12 to get the value of x. and that wil give us x ≤ 6, the sign did not change because we used a sign common to both sides to divide it. that is slso the reason why we had a positive value.
The line above the 6 and 3 means that those are recurring, so the full number is 2.63636363.... Recurring numbers can never be defined by decimals, because there is no end to the numbers repeating. It can only be defined by a fraction, so that means the number is irrational. Because it is between integers (a fraction that can't be simplified and will give a recurring decimal), it can't be a real number. All rational numbers are real numbers, but no irrational number can be a real number.
Therefore, your answer is 'Irrational number'.
Hope I helped!
6x-1=4x+6
subtracting 4x from each side
2x-1=6
adding 1 to each side
2x=7
divide by 2
x=7/2 or 3.5
check: 6(7/2) -1 =4(7/2)+6
21-1 =14+6
20=20 correct
Answer:
A and E
When doing problems like these it is easier just to see what numbers are divisbale by the ration.
Example:
A: 21/30
21 is divisable by 7 and 30 is divisbale by 10
E: 35/50
35 is divisable by 7 and 50 is divisbale by 10
