**Answer:**

25

**Step-by-step explanation:**

Given:

32 parks allow camping

43 parks allow playgrounds

10 parks both allow camping and playgrounds

110 total parks

First, we need to add 32, 43, and 10

32 + 43 + 10 = 85

Then, we find the difference of 110 and 85

110 - 85 = 25

Since it isn't a decimal, there is no point in rounding.

Solve by elimination.

2x-3y=-19

+(4x+3y=7)

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

6x=-12

**x=-2**

2(-2)-3y=-19

-3y=-15

**y=5**

**Intersection Point: (-2,5)**

**Answer:**

x = 10

**Step-by-step explanation:**

BF is two times AX so

2 ( 2x+10) = 5x+10

4x + 20 = 5x + 10

x = 10

**Answer:**

50 + number
