Answer:
C and D
Step-by-step explanation:
You can tell if equations have no solution if the variables on both sides of the equation are the same.
Choice C is 10+6x=15+9x-3x. You would combine 9x and -3x, turning the equation into 10+6x=15+6x. Since there is a 6x on both sides, Choice C would have no solution.
The same for Choice D. When you simplify everything there is a 3x on both sides, so it would have no solution.
Answer:
25
Step-by-step explanation:
the question basically translates to
160% x n =40
a little trick with percents I use is that the word "of" always means multiplication.
n=40/160%=25
Answer:
5.4
Step-by-step explanation:
3/5 x 9 is 5.4. To find the area of a rectangle you need to multiply the length times the width.
A)

The angle of elevation from point C to point A is
<em><u>Solution:</u></em>
Given that we have to find the angle of elevation from point C to Point A
Given in figure that, angle A =
Given is a right angled triangle ABC where angle B =
We have to find angle C
The angle sum property of a triangle states that the angles of a triangle always add up to 180°
Therefore, in given triangle ABC
angle A + angle B + angle C = 180
Therefore angle C =
