Answer:
option (c) is correct.
The given expression all real numbers at most –9.5 or at least 5.5 is written as b ≤ –9.5 or b ≥ 5.5
Step-by-step explanation:
Given expression all real numbers at most –9.5 or at least 5.5
We have to represent the given expression mathematically and choose the correct from given options.
Consider the given expression all real numbers at most –9.5 or at least 5.5
Let the real number be represented by b
then the given expression contain two terms
1) all real numbers at most –9.5
Mathematically written as b ≤ –9.5 .....(1)
2) all real numbers at least 5.5
Mathematically written as b ≥ 5.5 ....(2)
Thus, the given expression all real numbers at most –9.5 or at least 5.5 is written as b ≤ –9.5 or b ≥ 5.5
Thus, option (c) is correct.
newspapers did Martha deliver on the fifth day, if the
average number of newspapers she delivered per day
during the five-day period was 155?
A. 154
B. 162
C. 169
D. 171
Given the number of newspapers delivered by
E. Martha on the first four days, she cannot average
155 per day for the five-day period.
Answer:
C. 169
Step-by-step explanation:
144+152+139+171+169=775
775÷5=155
The equation that Berta determined could be 5x = - 10.
A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Berta determined that the solution is (- 2, 3).
From the given options the only x-coordinate value satisfying is
5x = - 10.
As at x = - 2.
5(-2) = - 10.
- 10 = - 10.
The solution (- 2, 3) can also be called as an ordered pair.

First determine how many miles the jet files in one hour:
470/2 =235 miles/hour
We want to know how many hours the jet could fly in 9 hours, so we multiply this value by 9.
235 x 9 = 2115 miles
Therefore, the jet could fly 2115 miles in 9 hours.
Answer:
235 miles per hour and 2,115 miles in 9 hours
