Step-by-step explanation:
Answer:
1 ≤ c ≤ 3
Step-by-step explanation:
In order to meet the standard, the chlorine level (c) must be at least 1 part per million (equal to or greater than 1):
1 ≤ c
At the same time, the level also needs to be no greater than 3 parts per million (equal to or lesser than 3)
c ≤ 3
Combining both inequalities yields (in parts per million):
1 ≤ c ≤ 3.
The compound inequality above describes the acceptable range for chlorine levels.
Answer: 4.83
Step-by-step explanation:
2.3*2.1= 4.83
Remember that straight lines are 180°. For #1 angle 1 would be 40°, since 140°+40°=180°
Answer:
1 oz of chips has 120mg of sodium, while in 1 cup of soda there are 50mg of sodium.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of mg of sodium in 1 oz of chips.
y is the number of mg of sodium in a cup of soda.
Bryan ate 5 oz of chips and drank 1 cup of soda for a total of 650 mg of sodium.
This means that:

Jadyn ate 1 oz of chips and drank 5 cups of soda for a total of 250 mg of sodium.
This means that:

From the first equation:

Replacing in the second






1 oz of chips has 120mg of sodium, while in 1 cup of soda there are 50mg of sodium.
