The square below repersents one whole express the shaded area as a fraction, a decimal, and a percent of the whole​
lord [1]
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%.

2x + 3y + x + 7 identidy the terms, like terms, coefficients, and constants in each expression
charle [14.2K]

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:

2x+3y+x+7

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.
