[tex]D)\ 25\%[/tex]
Step-by-step explanation:
The following equation can be used to relate the speed time and distance of an object in motion,
[tex](Speed)*(Time)=(Distance)[/tex]
One can also rewrite this equation in terms of time:
[tex](Speed)=\frac{(Distance)}{(Time)}[/tex]
Let this equation represent the relation between Mr.Wang's initial speed and travel time. However, in this problem, Mr.Wang faced a decrease in his speed, more specifically, a (20%) decrease. Subtract (0.2) from (1) to find Mr.Wang's speed in relation to his original speed. Let (x) represent the increase in time that Mr. Wang had to incur in order to reach his destination. Model this situation,
[tex](Speed)*(Time)=(Distance)[/tex]
[tex]0.8(Speed)*x(Time)=(Distance)[/tex]
Now use inverse operations to solve for the coefficient (x):
[tex]0.8(Speed)*x(Time)=(Distance)[/tex]
[tex]x(Time)=\frac{(Distance)}{0.8(Speed)}[/tex]
Using the relation state above: ([tex](Speed)=\frac{(Distance)}{(Time)}[/tex]) one can state the following:
[tex]x(Time)=\frac{(Distance)}{0.8(Speed)}[/tex]
[tex]x(Time)=\frac{1}{0.8}(Time)[/tex]
Thus, (Time) can be omitted from this equation, as it appear on both sides as a factor, hence one can then solve for (x):
[tex]x(Time)=\frac{1}{0.8}(Time)[/tex]
[tex]x=\frac{1}{0.8}[/tex]
Divide (1) by (0.8):
[tex]x=\frac{1}{0.8}\\x=0.25[/tex]
Multiply the decimal by (100) to put it into the percent form:
[tex]x=0.25\\x=25\%[/tex]

Answer:
x is all real numbers
Step-by-step explanation:
4(x + 1) = 4x + 4
Distribute
4x+4 = 4x+4
Subtract 4x from each side
4x+4-4x = 4x+4-4x
4=4

727÷9 Pleaase HEEEELLLPPP!!!!!!!!
Answers
Answer:
80.77777778
Step-by-step explanation:
when dividing 727 by 9, think about how many times does 9 go into 7? none.
next how many times does 9 go into 72? 8 times!
but since we have established 9 cannot go into 7 we need to know how many times does 9 go into 727, since it goes into 72 8 times already try adding a zero behind that 8. So what is 80(9)? it's 720. So the answer would be 720 with a remainder of 7. :)

In a triangle, two angles have measures of 45 degrees and 85 degrees. What is the measure of the third angle in this triangle?
Answers
Answer:
50 degrees
Step-by-step explanation:
All three angles in a triangle add up to 180 degrees. If you know the measure of two angles, add them together and subtract the sum from 180.
45+85=130. Then, subtract 130 from the total, or 180. 180-130=50. The measure of the third angle of the triangle is 50 degrees.
