Is -2 a solution to x < -2? Is -2 a solution
to x < -2? Explain your answers.
Answer:
See below.
Step-by-step explanation:
x < -2 means that x is any number that is less than -2.
Is -2 less than -2? Answer: No.
A number is equal to itself. A number is not greater than itself or less than itself.
When the solution to an inequality is x < -2, the only values of x that are valid are numbers less than -2. -2 itself is not a valid solution.

Answer: C. [tex]26.2\div1\dfrac{31}{100}[/tex]
Step-by-step explanation:
Given: A marathon is 26.2 miles long.
There is a water station every[tex]1\dfrac{31}{100}[/tex] miles along the race route.
Total number of water stations = (marathon distance) ÷ (distance between any two water stations)
The expression represents the total number of water stations[tex]=26.2\div1\dfrac{31}{100}[/tex]
Hence, the correct option is C.

Jason is saving up to buy a digital camera that costs $490. So far, he saved $175. He would like to buy the camera 3 weeks from now. What is the inequality used to represent how much he must save every week to have enough money to purchase the camera?
Cost of Camera = $490
Money saved so far = $175
Money required to save in 3 weeks =490–175 =315
Let y represent the money to be saved and x represent the money to be saved per week
Then x = y/3 or 3x = y is the equation

Quincy drew a map of Galveston Island. In the scale Quincy used for the map, 2 centimetres represents 10 kilo meters. Galveston Island is actually 43.5 kilo meters long. What is the length in centimetres of Galveston Island on Quincy's map?
Answer:
8.7cm
Step-by-step explanation:
From the question, we know that:
10 km = 2 cm(on the map)
43.5 km = x cm
Cross Multiply
10 × x cm = 43.5km × 2
x cm = 43.5 km × 2/10
x cm = 8.7 cm
The length in centimetres of Galveston Island on Quincy's map is 8.7cm
Mathematics, 24.05.2020 00:00, aj2869 Franklin needs 1.25 meters of ribbon To wrap each gift. He had a spool of... Franklin needs 1.25 meters of ribbon To wrap each gift. He had a spool of ribbon that contains 25 feet of ribbon that contains 25 feet of ribbon. One meter is equivalent to approximately 3 feet. How many gifts of the same dimension can he wrap using the spool of ribbon
Answer:
He can wrap 6 gifts using the spool of ribbon
Step-by-step explanation:
Here, we want to know the number of gifts of the same dimension that Franklin can wrap using the spool of ribbon
Per gift 1.25m of ribbon is needed
Now in the spool, there is 25 feet of ribbon
1 m = 3 feet
x m = 25 feet
x = 25/3 meter
so the number of gifts of the same dimension he can wrap using the spool of ribbon will be;
25/3/1.25 = 25/3.75 = 6.67
Since he cannot wrap a gift fractionally, the number of gifts he can wrap is thus 6
A teacher buys 4.25 ounces of a compound for an experiment. The compound costs $2.32 per ounce. The teacher pays with a $10 bill. How much change does the teacher receive?
Given:
Compound for an experiment = 4.25 ounces
Compound costs = $2.32 per ounce.
Teacher pays = $10
To find:
The amount of change teacher receive.
Solution:
Cost of 1 ounce of compound = $2.32
Cost of 4.25 ounce of compound = 4.25 × $2.32
= $9.86
It is given that, the teacher pays with a $10 bill.
Amount of change = $10 - $9.86
= $0.14
Therefore, the teacher receive $0.14 change.

The population of fish in a certain lake increased from 370 to 420 over the months of
March and April. At what rate is the population increasing?
Answer:
50 new fish in total
so lets say 25 per month
Rate: 25 fish per month
Step-by-step explanation:
The rate is the population increasing is 0.135 or 13.5% .
What is Growth rates?Growth rates refer to the percentage change of a specific variable within a specific time period.
Growth rate= [tex]\frac{Present value - Past value}{Past value}[/tex]
According to the question
The population of fish increased from 370 to 420
i.e
Present value = 420
Past value = 370
over the months of March and April
By using Growth rate formula :
Growth rate= [tex]\frac{Present value - Past value}{Past value}[/tex]
Now,
Substituting values in formula
Growth rate= [tex]\frac{420 - 370}{370}[/tex]
= [tex]\frac{50}{370}[/tex]
= 0.135 or 13.5%
Hence, the rate is the population increasing is 0.135 or 13.5% .
