Answer:

Issac's dog weighs 19 pounds

Step-by-step explanation:

Let x be Issac's dog's weight

Translate the problem into an algebraic expression: x + (x + 12) = 50
Simplify: 2x + 12 = 50
Subtract 12 from each side, so it now looks like this: 2x = 38
Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 19

I hope this helps!

A local gym instructor has a course load that allows her to teach eight classes. At an interest meeting, 8 people wanted high-‐

Answer:

The final curse load of the local gym instructor is this:

High-‐impact aerobics = 1

Low-‐impact aerobics = 4

Jazzercise = 1

Step exercise = 2

Step-by-step explanation:

1. Let's apportion the class load using the Hamilton method

Number of classes the local gym instructor can teach = 8

Total number of students that want to take a class = 114 (8 people wanted high-‐impact aerobics, 64 wanted low-‐impact aerobics, 11 wanted jazzercise, and 31 wanted step exercise)

Standard divisor = 114/8 = 14.25

Now, we can apportion the students in in Standard quotas, this way:

High-‐impact aerobics = 8/14.25 = 0.5614

Low-‐impact aerobics = 64/14.25 = 4.49

Jazzercise = 11/14.25 = 0.7719

Step exercise = 31/14.25 = 2.1754

Now, we find the Minimum quota, just considering the whole number and don't taking into account the decimals, this way:

High-‐impact aerobics = 0

Low-‐impact aerobics = 4

Jazzercise = 0

Step exercise = 2

As we can see we have 6 classes and there are 2 still pending. Those 2 goes to the classes with the highest decimal portion, in this case, Jazzercise .7719 and High-‐impact aerobics with .5614.

The final course load is this:

High-‐impact aerobics = 1

Low-‐impact aerobics = 4

Jazzercise = 1

Step exercise = 2

X= 14

2(X+4) = 2x+8
3x-6 = 2x+8
-6=2x-3x+8
-14 = -1x
