Answer: x=-1,1

Step-by-step explanation:

16x^2+9=25 first we subtract 9 from the right and left sides.

16x^2=16

Divide both sides by 16 to isolate x

x^2=1

Take the square roots of both sides to isolate x completely.

x=1,-1

Marisa took a survey and discovered that 38 out of 152 students in the seventh grade at her school have more than one pet. What
mamaluj [8]

Answer:

<h3>25%</h3>

Step-by-step explanation:

Total number of student in the school = 152 students

Number of student that have more than one pet = 38

percentage of the students have more than one pet will be expressed as

% of student with more than 1 pet = number of student with more than one pet/total number of student * 100%

% of student with more than 1 pet = 38/152 * 100

% of student with more than 1 pet = 3800/152

% of student with more than 1 pet = 25%

Hence 25% of the students in the school have more than one pet.
