Answer:
z = - 0.78
Step-by-step explanation:
Given:
1/3(6z+7.2)=0.5(8z+2)-0.4
Open parenthesis
2z + 2.4 = (4z + 1) - 0.4
2z + 2.4 = - 1.6z - 0.4
Collect like terms
2z + 1.6z = - 0.4 - 2.4
3.6z = -2.8
z = -2.8 / 3.6
= - 0.78
Answer:
66.66
Step-by-step explanation:
So for this one all you really have to do is turn 2/3 into a precent which is pretty easy.
This fist step to this would just be dividing 2 and 3
2/3=0.66666666666666666666 (and on and on and on)
Now just move the decimal 2 times to the right
66.6666666666666666666666
And of course round it, and in this case to the hundreth place
66.66
Answer:
3/7
Step-by-step explanation:
The number of possible results are;
1, 2 , 3 , 4 , 5, 6 , 7 = 7
odd numbers here are;
1, 3 , 5 and 7
non-odd numbers are 2, 4 and 6
So the section not labeled with an odd number is 3
Hence the probability here is that;
3/7
