Answer:
The simplified form of given expression is 3/5.
Step-by-step explanation:
The given expression is
We need to find the product of two factions using diagram.
For 3/4, draw a box and divide it in 4 equal parts by using vertical lines. The color three parts of it.
For 4/5, draw a box and divide it in 5 equal parts by using horizontal lines. Then color the four parts of it.
Now combined both boxes and shown below.
From the below figure it is clear that
The number of common shaded small boxes = 12
Total number of small boxes = 20
The required fraction is
Cancel out common factor.
Therefore, the simplified form of given expression is 3/5.
Answer:
Step-by-step explanation:
Represent the width by W. Then, "The length of a rectangular field is 7 m less than 4 times the width" expressed symbolically is
L = 4W - 7 (dimensions in meters)
Recall that the perimeter formula in this case is P = 2L + 2W, and recognize that the perimeter value is 136 m. After substituting 4W - 7 for L, we get:
136 m = 2(4W - 7) + 2W, or
136 = 8W - 14 + 2W, or
150 = 10W These three equations are equivalent mathematical statements.
150 = 10W reduces to W = 15 (meters).
Part A: the independent variable is W, the width of the field.
Part B: The mathematical statement is 136 m = 2(4W - 7) + 2W, which after algebraic manipulation becomes 150 = 10W.
Part C: The above equation can be solved for W: W = 15 meters. This is the value of the independent variable.

Answer:
e ^1/2
Step-by-step explanation:
All you do is take the fraction (4/8) and just simplify that part
4 divided by 2 = 2
8 divided by 2 =4
I got 2/4 but I can simplify more
2 divided by 2= 1
4 divided by 2 = 2
Now I got 1/2
And I would just leave e alone so my answer is e ^1/2
Do you kinda get what im saying?
Answer:
x = 7
Step-by-step explanation:
We know that adding TUW and WUV will give TUV.
So you can substitute the given equations for each and form a lengthy equation
5x + 3 + 10x -5 = 17x - 16
Move all the variables to one side, and the constants to the other
5x + 10x - 17x = -16 - 3 + 5
Simplify!
-2x = -14
x = 7
