sesenic [268]

Answer:

15 lb

Step-by-step explanation:

let the current weight of the puppy be X, the  initial weight of the puppy is 4lb or \frac{2}{3}X-6\ lb, (6 lb less 2/3 X) .

#We equate the current weight to the initial weight to determine X:

4\ lb=\frac{2}{3}X-6\ lb\\\\10 \ lb=\frac{2}{3}X\\\\X=15

Hence, the current weight of the puppy is 15 lb

Having some trouble with 6 can I get some help ?
balandron [24]
The answer is 13/15.

2/5 = 12/30
2/3 = 20/30

12/30 + 20/30 - 6/30 = 32/30 - 6/30 = 26/30 = 13/15.

Arrange the equations in increasing order of the value of their solutions.
Ulleksa [173]

See the explanation

<h2>Explanation:</h2>

The complete question is attached below. In order to solve this problem, we'll use a graphing tool. First of all, we'll say that the LHS is a linear function and the RHS is another linear function, so for each case, we'll have:

f(x)=g(x)

For each graph, f(x) will be drawn in red while g(x) will be drawn in blue.

Case 1:

f(x)=\frac{1}{4}x+\frac{5}{2}x-2 \\ \\ g(x)=4-\frac{1}{4}x

So by equating both equations:

\frac{1}{4}x+\frac{5}{2}x-2=4-\frac{1}{4}x

By using graphing tool we get a point of intersection at which the x-value is the solution to our equation. So:

<u>Solution:</u>

\boxed{x=2}

See First Figure below.

Case 2:

f(x)=7.9x+x+4 \\ \\ g(x)=-1.1x-16

Applying a similar method as in case 1.

<u>Solution:</u>

\boxed{x=-5.8}

See Second Figure below.

Case 3:

f(x)=3.2x+5.7 \\ \\ g(x)=-2.5x

Applying a similar method as in case 1.

<u>Solution:</u>

\boxed{x=-1}

See Third Figure below.

Case 4:

f(x)=10.1x-1.6x+44 \\ \\ g(x)=-7

Applying a similar method as in case 1.

<u>Solution:</u>

\boxed{x=-6}

See Fourth Figure below.
