The distributive property tells you
.. 5(x +z) = 5x +5z
You can't find a value of x since there is no equal sign. This is not an equation. It is just an expression, so you can't solve it for x.
The <u>correct answer</u> is:
Experiment
Explanation:
In an experiment, one group is given a treatment while at least one other group is not. After the treatment is finished, the results of the group that receive the treatment are compared with the results of the group (or groups) that do not receive the treatment, to determine if the treatment had any effect on the group.
In this problem, the different groups are the classes. Some classes use the new method, which is the treatment, while other classes do not. At the end of the year, the reading results of each class are compared to see if the treatment (new method) had any effect.
Answer:
1.84
Step-by-step explanation:
So first we can do 5/7 which equals 0.714286
add 2 to that and get: 2.714286
So 5 / 2.714286 = 1.8421
