Answer:

Step-by-step explanation:

30 is the b in this equation which represents the number of miles she has already jogged. 6 represents the number of miles she jogs every day for x amount of days. x could be 5, in which case it would be represented as 6*5+30=60. But since we don't know what x is, it is just 6x+30.

The answer would be C.

Explanation:
Since she plans to jog 6 miles PER DAY, we know we’ll be using a variable- x. So we know that we’ll be using 6x, but that leaves the original 30 miles. Since the 6x is also talking about miles, it’s a matter of addition. This brings us to the answer, 6x+30. I hope this helps!

Answer:

(7,2)

Step-by-step explanation:

x + y = 9 + 2x - 3y = 8 is really two equations, and you should show this by separating x + y = 9 from 2x - 3y = 8 through the use of a comma, or the word "and," or through writing only one equation per line.

Here you have the system of linear equations

x + y = 9

2x - 3y = 8.

Let's solve this system by elimination. Mult. the 1st eqn by 3, obtaining the system

3x + 3y = 27

2x - 3y = 8

-------------------

5x = 35, so that x = 7. Subbing 7 for x in x + y = 9, we get 7 + y = 9, indicating that y = 2.

Thus, the solution to this system of equations is (7,2).

Please note that dilation does not affect angles. Thus, if an image is dilated the angle remains the same and does not change.

Therefore, even if $\Delta ABC$ is dilated to $\Delta JKL$ by a factor of 1.5 (or by any factor for that matter), the linear dimensions of the original triangle $\Delta ABC$ will either get stretched or get shrunk by a factor of 1.5 but the angles of the original triangle will not be affected in any case.
