I would first add 5 and 2 together, then multiply that by 3. Finally you would subtract the 1. After solving for what is inside the parentheses you would multiply it by 2 for your final answer.
2•(3(5+2)-1)
2•(3(7)-1)
2•(21-1)
2•(20)
40
Answer: There are 20 students and 4 students are not here today.
Step-by-step explanation:
If the number of students = 4
Let the number of students be 'x'.
Fraction of students absent = 
If the number of students = 5
Fraction of students absent = 
And Jen came back,
So, the fraction of student absent is also written as
According to question, it becomes,
Hence, there are 20 students in our school.
And number of students are not here today is 
Answer:

Answer:
1 cubic ft can also be 1728in3, or 0.03704 yd3
Step-by-step explanation:
To find the cubic feet of a square or rectangular shape, measure the length, width and height of the object in feet or inches. Once you have these three numbers, multiply them together to get the volume. If you measured in inches, divide your answer by 1728 to convert the measurement to feet.
Answer:
Hi there!
The answer to this question is:
Standard: y= x- (cube root) z
the leading coefficient: 1
Step-by-step explanation:
when identifying a polynomial you always need to know the standard equation, and leading coefficient.
-you first need to know what "y" so you move y to the other side by adding it on both sides
-then you need to get y by itself and cube root it on both sides resulting in x^3 becoming x and z becoming (cube root) z
