I'm going to assume you mean:
13 * (3/4) + x = 7 * (1/4)
Let's go ahead and simplify the right side.
7 * (1/4) = 1.75
So now we have:
13 * (3/4) + x = 1.75
Now let's take care of the right side. Multiplication before addition.
13 * (3/4) = 9.75
9.75 + x = 1.75
To isolate x, we subtract 9.75 from both sides.
9.75 - 9.75 + x = 1.75 - 9.75
x = -8
Hopefully I spaced this well. \('-')/

Answer:
(A) x=5
Step-by-step explanation:
- The length of the pool is 20 feet,
- The width is (20 minus x) feet; and
- The area of the pool is 300 square feet.
Area = Length X Width
300 =20(20-x)
Opening the bracket on the right hand side
300 =400-20x
20x=400-300
20x=100
Divide both sides by 20
x=5
The value of x=5
Answer:
The maximum value of C is 68
Step-by-step explanation:
we have the following constraints
----> constraint A
----> constraint B
----> constraint C
----> constraint D
Find out the area of the feasible region, using a graphing tool
The vertices of the feasible region are
(0,0),(5,19),(5,0)
see the attached figure
To find out the maximum value of the objective function C, substitute the value of x and the value of y of each vertex in the objective function and then compare the results
For (0,0) ----->
For (5,19) ----->
For (5,0) ----->
therefore
The maximum value of C is 68
