1/4 hour is the same as 15 minutes. If it takes 15 minutes to paint 1/3, then it would take 45 minutes to paint the whole wall.
Answer:
terms, 2x, 3y , x and 7,
like terms, 2x, 3y, x and 7
Coefficient. 2 is the coefficient of 2x and 3 is the coefficient of 2y 1 is the coefficient of x
Constant. 7
Step-by-step explanation:
Given:

Terms are the number of parts in the expression.
there are four terms 2x, 3y , x and 7,
Like terms are the part of the polynomials. 2x, 3y and x are like terms because they both have an x attached. 7 is like terms because they have nothing attached.
The number that are attached to variable is called Coefficient.
So In the term 2x the number 2 is a coefficient because it is attached to x similarly 3y the number 3 is a coefficient because it is attached to y
and in the term x the number 1 is a coefficient.
Constant are the numbers that are not attached to any variable and it is not change. Such as 7 is the constant term.
Answer:
52%
Step-by-step explanation:
13×4= 52%
You just multiply by 4 to get the percentage
So i think this wan being
(8,1 x 10^5)
----------------- = 0,9 x 10^3 = 9 x 10^2
(9 x 10^2)
