X equals twelve divided by seven
Answer:
Step-by-step explanation:
3(7t - 5) - 2t = 4
3*7t - 3*5 - 2t = 4
21t - 15 - 2t = 4 {combine like terms}
21t - 2t - 15 = 4
19t - 15 = 4 {Add 15 to both sides}
19t = 4 + 15
19t = 19 {Divide both sides by 19}
t = 19/19
t = 1
Answer:
113.1
Step-by-step explanation:
Volume of sphere = 
× π × r²
Volume of sphere = × π × 3²
Volume of sphere = × π × 9
Volume of sphere = × 9 π
Volume of sphere = 113.1
K is 23.
As for the equation, it is
29=k+6
To solve, subtract 6 from both sides.
Answer:
5 classes.
Step-by-step explanation:
You can use the 
rule to determine the number of classes for a frequency distribution.
The rule says that 
where
is the number of classes
is the number of the data points
We know that the number of data points is = 20.
Next, we start searching for so that we can get a number 2 to the that is larger that the number of data points.
This suggests that you should use 5 classes.
