The radius of a circle is found by doing this :
circumference ÷ 6.28 = radius
The circumference here is 17.27 feet :
circumference ÷ 6.28 = radius
so
17.27 ÷ 6.28 = 2.75
The radius of the circle is 2.75 feet.
For number 3 it says
X - 9 for x=-5
X-9 = ___ -9
It gave you your x so you would just substitute and in result you will have an equation of -5 -9
It would give you -14 , since it’s 2 negatives being added ,because you double tapped . Hope this helps :)
First convert the numbers to get the same denominator
1/3=4/12
5/6=10/12
5/12
Then add them all together
4/12+10/12+5/12= 19/12
Then reduce
1 7/12
Your answer is 1 ton and 7/12 of a ton
2(3x-1) >=4x-6
6x-2>=4x-6
6x-4x>= -6+2
2x>=-4
x>=-2
You can see after simplification, the valve of x can be any number greater than or equal to -2. i.e -5 and -3 can not be in the solution set. the first choice can be dismissed, the fact the variable O could be any number that may not satisfy the solution. Therefore 0-1 is the answer, any thing between 0 & 1 including 0 and one satisfy the solution set
