Answer:
4) x = - 12
5) x = 4
Step-by-step explanation:
4)
Since points T and S are mid points of sides ML and MN of triangle MLN.
Therefore, by mid point theorem,
TS is half of LN
so,
[tex]x + 26 = \frac{1}{2} (x + 40) \\ \\ 2(x + 26) =x + 40 \\ \\ 2x + 52 = x + 40 \\ \\ 2x - x = 40 - 52 \\ \\ x = - 12[/tex]
5) In the same way x = 4 will be the correct answer in question number 5.

Two Grade 7 students, Monique and Matt, both solved the following math problem: If the temperature drops from 7°F to -17°F, by how much did the temperature decrease? The students came up with different answers. Monique said the answer is 24°F, and Matt said the answer is 10°F. Who is correct? Explain, and support your written response with details .
Answers
Answer: It decreased by 24F not 10F because if it were 10F the starting temperature had to be -7F since the difference between this number and -17F is 10F but in this case it starts at 7F so we subtract 7-0=7 and 17-0=17 and add 17+7=24F.
Step-by-step explanation:
7-0=7
17-0=17
17+7=24F
The change in temperature is -24°F.
Monique said the answer of 24°F is true.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Step-by-step explanation:
The "experimental probability" is the ratio of actual outcomes of interest to the number of trials. It is based on actually performing the selection over and over some number of times. The "theoretical probability" will be the fraction that is the outcomes of interest divided by the total number of possible outcomes.
We note that Mel's purse contains a total of 6 +8 +4 +7 = 25 coins. The theoretical probability of selecting any given coin is then 1/25.

A. The experimental probability of selecting a dime is ...
number of dime outcomes / number of trials = 30/150 = 1/5
B. The theoretical probability of selecting a dime is ...
(4 dimes)/(25 coins) = 4/25
C. The assumption in probability experiments is that randomly selected outcomes will always approach the theoretical probability in their frequency of occurrence.
See the attachment for the appropriate answer choices.

sally runs 5km in 25 minutes. she plans to run in 20 km race. based on the current speed how long will it take her to complete the race?
Answers
Given:
Sally runs 5km in 25 minutes.
Total distance of race = 20 km
To find:
How long will it take her to complete the race?
Solution:
We have,
Time taken by Sally for 5 km = 25 minutes
Time taken by Sally for 1 km = [tex]\dfrac{25}{5}[/tex] minutes
= 5 minutes
Time taken by Sally for 20 km = [tex]20\times 5[/tex] minutes
= 100 minutes
= 1 h 40 minutes [ 1 h = 60 min]
Therefore, the time taken by Sally to complete the race is 1 h 40 minutes.

If m is the midpoint of CD, CM= 4x-5, and md=2x +5, find CM
Answers
Answer:
CM = 15
Step-by-step explanation:
since M is the midpoint of CD , then
CM = MD , that is
4x - 5 = 2x + 5 ( subtract 2x from both sides )
2x - 5 = 5 ( add 5 to both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Then
CM = 4x - 5 = 4(5) - 5 = 20 - 5 = 15

Answers
The area of the given figure is 100 cm².
In the above figure, we calculate total area by dividing the figure into two sub figures wherein we get a square portion of side 5 cm and a rectangular portion of length 15cm and breadth 5 cm. The area of the square and rectangle can be given as product of their two sides that is length multiplied by breadth.
Area of square portion = 5*5 = 25 square centimeter
Area of rectangular portion =15*5 = 75 square centimeter
Hence total area of the figure = Area of square portion + Area of rectangular portion.
Therefore, Total area of figure = 25 + 75 = 100 cm².

Let f(x) = 5x-7 and g(x) = 2x-3. Find f(x)+g(x)
Answers
Answer:
7x - 10
Step-by-step explanation:
f(x)= 5x - 7
g(x)= 2x - 3
f(x) + g(x)
= 5x - 7 + 2x - 3
= 7x - 10
The sum of f(x) and g(x) is 7x - 10.
To find the sum of f(x) and g(x), you simply need to add the two functions:
f(x) + g(x) = (5x - 7) + (2x - 3)
Now, combine like terms:
f(x) + g(x) = 5x + 2x - 7 - 3
f(x) + g(x) = 7x - 10
Therefore, the sum of f(x) and g(x) is 7x - 10.

6 / x + 10 = 2 / 15
6 / x = 2 / 15 - 10
6 / x = 2 / 15 - 150 / 15
6 / x = - 148 / 15
6 = ( - 148 / 15 ) x
6 ( 15 / - 148 ) = x

A cylinder trash can is 30in high and has a base radius of 7in. a manufacturer wants to know the surface of this trash can, including the top of the lid.
Answers
The surface area of the given cylinder trash can is 1,628 in²
The surface area of a cylinder is equal to the area of curved surface plus the area of flat surfaces. The flat surfaces are the base and the lid.
Area of the curved surface = 2 π.r.h
Area of the flat surfaces = 2 π.r²
Hence,
Total surface area of a cylinder = 2 π.r.h + 2 π.r²
= 2 π.r (h + r)
Where:
h = height
r = radius of the base
Parameters given:
h = 30 in.
r = 7 in.
Substitute these parameters into the formula:
Area = 2. (22/7) . 7. (7 + 30)
