Answer: x=15
Answer: x=15
.......
Answer:
<h2>18%</h2>
Step-by-step explanation:
Step one;
given
initial weight = 55 pounds
final weight= 45 pounds
Step two:
Required
the % weight decrease
% decrease= initial-final/initial *100
% decrease= 55-45/55 *100
% decrease= 10/55 *100
% decrease= 0.18 *100
% decrease= 18%
The answer to question #1 is x = 7
For a line to be parallel to x = 8, it has to start with x = some number. Such a line would have an undefined slope.
Now, x = y is a line that goes through the origin. It has a slope of 1.
The answer to question #2 is y = 7
If a line is perpendicular to x = some number, then it has to be y = some number.
And this perpendicular line has to go through the point (4,7). So what is the y-value of this point, since the equation starts with y? The y-value is 7. So the equation has to be y = 7
CB is equal to 10m you can tell this bye the side DC being 20 m and the angle of DC is half of CB so that means that CB has to be 10 m
