Let, the number of books on Monday = m
On Tuesday = 2m
On Wednesday = 2m - 6
Equation: m + 2m + (2m - 6) = 19
You can solve it:
5m = 19 + 6
m = 25/5
m = 5
In short, He sold 5 books on Monday
Hope this helps!
5-y/2 = 9
First, we do the inverse operation and subtract 5 from both sides.
5 - y/2 = 9
-5 -5
-y/2 = 4
Now, we do the inverse operation ( multiply by the reciprocal)
-y/2 = 4
-y/2 * -2 = 4* -2
y= -8
y=-8
Now we have our final answer: y=-8
Check our work
5 - - 8/2= 9
5+4=9
9=9
OUR ANSWER IS CORRECT! :)
Let x be the brick portion of the wall
Since x is 2/3 of the wall
Then x= (2/3)(2 3/4)
x= 11/6 = 1 5/6
So the brick portion of the wall is 1 5/6 feet
Note: that's not 15/6, it's a mixed fraction which is 1 + 5/6.. just to let you know
Construct two angle bisectors of the triangle
Answer:
Option (D) is correct
<u>Step-by-step explanation:</u>
We have to contruct two angle bisectors of the triangle.
various steps to inscribe the circle in a triangle are
- First draw a triangle
- Draw angle bisector of one angle
- Draw angle bisector of another angle
- Extent these angle bisectors, where they meet that point will be called the incenter
- From incenter draw prependicular to any side of the triangle
- The length from the point where the prependicular touches the side of triangle to the point of incenter will be radius.
- Use this radius and draw the incircle.
