Answer:

Step-by-step explanation:
Given
- 2a - 5 > 3 ( add 5 to both sides )
- 2a > 8
Divide both sides by - 2, reversing the direction of the inequality sign as a consequence of dividing by a negative quantity
a < - 4
Since a is less than we require an open circle at - 4 on the number line.
Since less than the arrow head is pointing to the left, that is
Graph A, the top graph illustrates the solution
Thirty-six and twenty eight.
We are given that the angle a is the right angle. So let
us work from this.
ab = 12 (the vertical side of the triangle)
bc = 13 (which if drawn can be clearly observed to be the
hypotenuse) = the side opposite to angle a
ca = 5 (the horizontal side of the triangle)
Since we are to find for the cosine ratio of angle c or
angle θ, therefore:
cos θ = adjacent side / hypotenuse
cos θ = ca / bc
cos θ = 5 / 13
Check out the attached image below for the illustration
of the triangle.
To find the area of a rectangle, you times the length and width together.
So in this case,
5/8 x 2/3 = 10/24.
This can be simplified to 5/12
Answer:
10/14, 15/21, and 20,28
Step-by-step explanation:
You just need to multiply a number on the numerator and the denominator. Remember, whatever you do to the numerator you have to do on your denominator.
