Dmitrij [34]

Answer:  No, he can't pass the course.

Explanation:

Since we have given that

Marks on tests 1, 2, and 4 are given by

82, 76, 90 respectively.

Unfortunately, he cut the third test and receive a 0.

According to question, we have given that passing grade for the course is 70, and his one test left to take ,

Let the marks obtained in fifth test be x

So,

\frac{82+76+90+0+x}{5}=70\\\\248+x=5\times 70=350\\\\x=350-248\\\\x=102

And it is not possible to get 102 over 100.

so, he can't still pass the course.

Hence, No, he can't pass the course.

I know the answer to 255.5 ➗ 7 but how would you write it out.. (I'm not smart)
Ainat [17]
There are several ways such as
255\frac{1}{2} / 7

First put it in the decimal equation
Since there is a decimal in the number being divided(255.5), you move the decimal so that it is a whole number(2555) but since you move the decimal place once, you do the same to the 7 so that it is now 70. So now it's 2555/70 which looks like 365 but then, you have to place the decimal value so that it is now 36.5
This is what you use to divide as shown.
