Answer:
AB = 54
Step-by-step explanation:
DE is a midsegment of the triangle and is half of AB , that is
2x + 13 = [tex]\frac{1}{2}[/tex](13x - 37) ← multiply through by 2 to clear the fraction
4x + 26 = 13x - 37 ( subtract 13x from both sides )
- 9x + 26 = - 37 ( subtract 26 from both sides )
- 9x = - 63 ( divide both sides by - 9 )
x = 7
Thus
AB = 13x - 37 = 13(7) - 37 = 91 - 37 = 54

Answers
Answer:
No, you are not changing the value.
Step-by-step explanation:
Answer:
No, because then it would have different values and it wouldn't be rewriting it.
Step-by-step explanation:
Ex. 1/2. The decimal for this would be 0.5, right?
We aren't changing the value of the fraction. It is just another way of writing the value.

Note the rules of multiply/dividing negative numbers:
1) A positive number multiplied/divided by a positive number = a positive answer.
2) A positive number multiplied/divided by a negative number (and vice versa) = a negative answer.
3) A negative number multiplied/divided by a negative number = a positive answer.

The first part is multiplying a negative number with a negative number:
(-) * (-) = (+) , based on the rules given above.
Next, multiply the next number. Note that it is also a negative number:
(+) * (-) = (-) , based on the rules given above.
b. - is your answer.

Michelle is scuba diving. Her position changes from -2.1m to -38.6m in 6 1/4 min. What is the average change in Michelle's position each minute?
Answers
Answer: 5.824 m / min
Step-by-step explanation:
Change in position = -2.1m to -38.6m
Distance = |-38.6 m - (-2.1m) |
=|-36.5| m
= 36.5 m
Time = [tex]6\dfrac14\ min=\dfrac{6\times4+1}{4}\ min[/tex]
[tex]=\dfrac{25}{4}\ min[/tex]
The average change in Michelle's position each minute = [tex]\dfrac{36.5}{\dfrac{25}{4}}\text{ m/min}[/tex]
[tex]=\dfrac{36.4\times4}{25}\text{ m/min}\\\\= 5.824\text{ m/min}[/tex]
Hence, the average change in Michelle's position each minute = 5.824 m / min

Westminster Street and Lake Avenue intersect. If Westminster Street is 7 meters wide and Lake Avenue is 5 meters wide, what is the distance between two opposite corners of the intersection? If necessary, round to the nearest tenth.
Answers
Answer:
the distance between two opposite corners of the intersection is 8.60 meters
Step-by-step explanation:
The computation of the distance between two opposite corners of the intersection is given below:
Here we applied the Pythagoras theorem
[tex]= \sqrt{7^2 + 5^2} \\\\= \sqrt{49 + 25} \\\\= \sqrt{74}[/tex]
= 8.60 meters
hence, the distance between two opposite corners of the intersection is 8.60 meters

Let "S" be the price of sales. Then the equation is given as,
30% = [($40 - S) / $40] x 100
0.30 = ($40 - S) / $40
S = $40 - $12
S = $28
