Because there are 10 parts in the whole and 2 are shaded, the square can be represented as 2/10 shaded. this can be simplified to 1/5 since the numerator and denominator are both divisible by 2. to convert 1/5 to a decimal, we divide 1 by 5, which results in .2, which we can then convert to a percentage by moving the decimal place two times to the left. therefore, as a percent, the square is shaded 20%.
Brady studied for 4.5 hours that week
How we determine the total study hours?
The total study hours for Brady is the sum of the hours used in studying on Monday, Tuesday, Wednesday and Thursday.
He studied for 1.5 hours on Monday
He studied for 0.75 hours on Tuesday
He studied again for 1.25 hours on Wednesday
Lastly, he studied for 1 hour on Thursday, the last day

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.
