Answer:
Step-by-step explanation:
To find an expression equivalent, we can simply distribute the 
:
Step-by-step explanation:
Hey there!!
During evaluating the expression, you must follow,
- put the value as given.
- work according to the mathematical operation sign.
Here,
= 30+36
= 66.
ii). b-4c
= 30 - 4×6
= 30 - 24
= 6

The statement is false for any value of x because both sides are identical after distributing and collecting like terms -10x-5>-5-10x making it equal and not bigger
Answer:
10 feet
Step-by-step explanation:
Assuming this means below sea level, think of 30 feet as a -30. The destination you need to get to is -20, so you would need to swim up 10 feet.
Answer:
B. The given value is a for the because the data collected represent a . statistic year sample
Step-by-step explanation:
A population is the total of similar items that are of interest to the researcher.
Since the researcher cannot measure each of these items he chooses a part of it to measure. This part of the population is called a sample.
A good sample is representative of the larger population. Deduction made from the sample is used to represent the whole population.
In this scenario the population is the whole year, and the sample is 41 days.
So the mean derived from the sample is statistic of sample from the year.
This can be used to make deductions about the whole year.
