The trick it to separate the 7/10 relating to the x-coordinates from the 7/10 relating to the y-coordinates.

**For the x-coordinate:**

You need to find the difference in the x-values

12-(-4) = 16

and then find 7/10 of that and add it to the starting x-coordinate (the x-coordinate of Point A).

**For the y-coordinate:**

You need to find the difference in the y-values

4-(-5) = 9

and then find 7/10 of that and add it to the starting y-coordinate (the y-coordinate of Point A).

Can you take it from there?

**Answer: **198 in.²

**Step-by-step explanation:**

If two shapes are congruent they have the same shape and size.

A = L x W

18 x 11 = 198

**Answer:**

**Step-by-step explanation:**

-6x+5y=11

If x= -1 replace x with -1

-6(-1)+5y=11

6+5y=11 subtract 6 from both sides

5y=5 divide by 5

y=1

**Answer:**

$8,910

**Step-by-step explanation:**

His old salary was 90% of his new salary. You will find 90% of 9,900 or 9,900x.9

When you multiply 9,900 to .9, you get 8,910.

Therefore, your answer is $8,910

**Answer:**

**Step-by-step explanation:**

50% of 60? 0.5*60=30

10% of 60? 0.1*60=6

75% of 60? 0.75*60=45
