24x-1+20x+5=180
44x+4=180
44x=176
x=4

Therefore, 20x+ 5 is equivalent to 20(4)+5
20(4)+5
80+5
85

Hope this helps :)

A dog trainer has 104 ft of fencing that will be use to create a rectangular work area for dogs. If the trainer wants to enclose
Andrews [41]

Answer:

The dimensions of the work area are 16 ft by 36 ft

Step-by-step explanation:

Let

x ----> the length of the work area in feet

y-----> the width of the work area in feet

we know that

The perimeter of the work area is equal to

104=2(x+y)

simplify

52=(x+y)

y=52-x ----> equation A

The area of the work area is equal to

576=xy ---> equation B

substitute equation A in equation B

576=x(52-x)

576=52x-x^2

x^2-52x+576=0

solve the quadratic equation by graphing

using a graphing tool

The solutions are

x=16 ft, y=36 ft

or

x=36 ft, y=16 ft

see the attached figure

therefore

The dimensions of the work area are 16 ft by 36 ft

A. (1.34)(5.46) = (1.76)(x)
Alja [10]
We are given an equation with an unknown variable x. We can find the value of x by dividing both sides by 1.76, as this will leave only x on the right hand side of the equation and its value on the left hand side, as shown below:

(1.34)(5.46)=1.76(x) \\  \\ 
 \frac{(1.34)(5.46)}{1.76} = \frac{1.76(x)}{1.76}  \\  \\ 
 \frac{(1.34)(5.46)}{1.76} =x \\  \\ 
4.16=x

Thus solving the given equation, we get x =4.16, rounded of to nearest hundredth.

These 3 questions pleaseeee!
Sergio039 [100]

Answer:

1. m<T =72 , m<U =54

2. EF= 18 in. , m<F=134'

3. x=4

Step-by-step explanation:

1. <s=<u , there is 180' in a triangle total so 180- <S - <U = <T

180 - 54 - 54 = 72

2. ef = gf

180 - 23 - 23 = 134

3. since bottom 2 angles are = , the 2 sides are also =
