What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
The equation |x – 72.5| = 4.
The minimum and maximum temperatures can be found by substituting +4 and -4 in x.
Minimum temperature,
⇒ [tex]|+4-72.5|=|-68.5|[/tex]
⇒ [tex]68.5[/tex]
Maximum temperature,
⇒ [tex]|-4-72.5|=|-76.5|[/tex]
⇒ [tex]76.5[/tex]
Hence we can conclude that to keep the house in heat, the minimum and maximum temperature is set to option 68.5°F and 76.5°F.

drugs is the most important problem.
Drugs is the most important problem for approximately how many of the high school teenagers?
A 11.200.000
B. 1.400.000
C. 2.800.000
D. 8,400,000
Answers
Answer:
Option (C)
Step-by-step explanation:
From the circle graph attached,
14158428 students have been divided into the sectors of a circle which represent the most important problems for the high school teenagers.
Each sector corresponds the percent of different problem.
Red sector (22% of the total students) represents the most important problem of drugs.
14158428 students ≈ 14000000
22% ≈ 20%
Now 20% of 14000000 high school students = 14000000×[tex]\frac{20}{100}[/tex]
= 2800000
Therefore, Option (C) will be the answer.

A can factory requires 2 sheets of metal to make 36 cans and 10 sheets of metal to make 180 cans. The proportionality constant between the number of cans made and the number of sheets of metal used is 36 18 288 5
Answers
Answer:From the statement above, we can say that there is a direct relationship between the number of sheets used to the number of cans that can be made. That is, # of sheets is directly proportional to # of cans. We make an equation as follows:
let y = # of sheets
x = # of cans
y = kx where k is the proportionality constant
Assuming linear relationship of the two, we can use either data point as follows:
y = kx
2 = k(36)
k = 1/18
Therefore, the proportionality constant is 1/18.

Jennifer paid $13.37 for a pack of 12 pairs of sport socks. What was the price of a pair of sport socks
Answers
Answer:
Each pair of socks cost around $1.11 excluding taxes.
Step-by-step explanation:
To find how much it costs for one pair of socks, divide the cost with how many pairs there are.
13.37/12 = 1.11426...
Since we are determining the cost of each pair of socks, it's only justifiable if we round it to the nearest hundredths.
Therefore, a pair of socks cost around $1.11 excluding taxes.

As per the circumference of a circle, the length of the paper is 176 mm.
What is the circumference of a circle?The circumference of a circle is the total arc length of it.
The diameter of the pencil is(d) 7 mm
Therefore, the radius of the pencil is(r)
[tex]= \frac{d}{2} \\= 7/2 mm\\= 3.5 mm[/tex]
Now, the circumference of the cross-section of the pencil is
[tex]= 2[/tex](π)r units
[tex]= (2) (22/7) (3.5) mm\\= 22 mm[/tex]
Therefore, the length of the paper is

The values of x for which the result of 5 x be greater than 1 would be 2 and 3.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
WE need to find the values of x for which the result of 5 x be greater than 1
WE can have that as;
2+3=5
or
3+2=5
Also we can continue on but we would need to use one and these are the two that are greater than 1 but make up 5.
Therefore, the values of x for which the result of 5 x be greater than 1 would be 2 and 3.

you can transform 4x + 12 = 9x - 3 again into a simpler form by subtracting 4x form both sides to get 12 = 5x - 3, if you subsitute 3 for x in 12 = 5x - 3, do you still get a true statement
Answers
Answer: Yes you will still get a true statement because 3 is the solution to the equation.
Step-by-step explanation:
Well substitute 3 for x into the equation and solve for to see if they equal each other.
12 = 5(3) - 3
12 = 15 - 3
12 = 12
So if you substitute 3 you get the solution .
Now solve for x in the real equation to see if you get 3.
4x + 12 = 9x -3
-4x -4x
12 = 5x -3
+3 +3
15 = 5x
