Answer:

i think the answer is <u> 7 - x = 8</u>

Step-by-step explanation:

Let me explain why i think that is the answer. First off, i turned the problem around so it was easier for me to solve.

I think that it stays '7 - x' because they arent like terms so you cant combine them, so i think that stays the same. Because i cant change that, i added '2 + 9' and i got 11. I then took the 11 and subtracted it by itself and the 19. Because i subtracted it by itself, the 11 canceled out and i got 8 from the 19 - 11. Like i said, i couldnt do anything with the ' 7 - x' i ended up with 7 - x = 8.

Answer:

x = 12

Step-by-step explanation:

First you need to use the distributive property.

19 = 9 + 2x - 14

Then you should simplify (9-14)

19 = 2x - 5

+5         +5  (Then add 5 to both sides)

24 = 2x

/2     /2    (Divide by 2 to get x by itself)

12 = x

Hope this helps!!!

A) Scale of map is 1: 30,000

This is assuming that it meant 1 centimetre = 30,000 metres, for it gives no other information.

Multiply 1 with 30,000: 30,000 x `1 = 30,000

30,000 metres is your answer.

B) Scale is 1 inch: 6 miles. You are given 2.5 inches.

Remember that 1 inch = 6 miles.

Multiply 2.5 to both sides: (2.5) * 1 inch = (2.5) * 6 miles

2.5 inch = 2.5 * 6 miles

2.5 inch = 15 miles

15 miles is your answer.
