So Marci's sore was 45 because every percent has to be out of 100 so to get it to 50 you divide by two so 90 / 2 = 45. And 45-39 = 6 

Marci got 6 more correct then Donovan.

Observe the expression below and select the true statement(s).<br><br> 3y(7 + 2x) + 9xy - 10
Sedaia [141]

Answer:

The "3y" in the first term is a factor

The "9" in the second term is a coefficient

The "(7 + 2x)" in the first term is a factor

Step-by-step explanation:

Given in the question an expression

3y(7 + 2x) + 9xy - 10

  1. The coefficients are the numbers that multiply the variables, x and y.
<h3>Example</h3>

6y

6 is coefficient

    2.Constants are terms without variables

<h3>Example</h3>

 10

    3.The factors in a mathematical expression are parts of the expression that are connected with multiplication.

<h3> Example</h3>

(4x+1)(3x+7)

(4x+1) and (3x+7) both are factors
