Simplify both sides:
x
—- = -9
4
now isolate the variable (x):
x= -9 • 4
x= -36
Answer: She can randomly survey 50 seventh-graders in the school.
Step-by-step explanation: To get the best result without wasting to much time means she cannot afford to survey every student. To receive the best results it should be unbiased so random is the way to go. Randomly surveying 50 girls in her school does not guarantee that those girls are all seventh graders so the best answer is She can randomly survey 50 seventh-graders in the school.
Answer:
There are 5 boxes on the tenth row.
Step-by-step explanation:
We are given the following information in the question:
Each row of tissues has 2 fewer boxes than the row below.
The first row has 23 boxes of tissues.
23, 21, 19, 17,...
a) Let f(x) be the function that represent the arithmetic sequence.
Then,
, where x is the number of boxes in previous rows.
b) Comparing the given sequence to an arithmetic progression, we have
First term,a = 10
Common difference,d = -2

Thus, there are 5 boxes on the tenth row.
Answer:A
It can not be c and d
Equation 1 has a negative 1/4
