**Answer:**

Value of boat = $23,400

Loss of value by boat per year = 8%

To find: - Monthly percent decrease in value of boat.

Solution: - Decrease of value per year = 8% of $23,400 = $1,872. Monthly decrease in value = $1,872/12 = $156. Monthly percentage decrease = ($156/$23,400) * 100 = 0.6667 or 0.67 (rounded to nearest hundredth)

**Answer:**

17a + 16 =

**Step-by-step explanation:**

Add all a's

then all numbers w/o letters

you cannot add them together bc it would be like adding apples to carrots (thats what my teacher said)

**Answer:**

x+3y=-1

**Step-by-step explanation:**

y=3x-2 so m=3 old slope

the new slope must be -1/3 (opposite reciprocal of the old slope).

y-y0=m*(x-x0)

y-2=-1/3*(x-(-7))

y-2=-1/3x-1/3*7

y-2=-1/3x-7/3

3y-6=-x-7

The standard form for linear equations in two variables is Ax+By=C.

x+3y=6-7

x+3y=-1

**Step-by-step explanation:**

= -4 ÷ ( 1/3 × (7 - 1/2) ) + 3

= -4 ÷ ( 1/3 × 13/2 ) + 3

= -4 ÷ 13/6 + 3

= -4 × 6/13 + 3

= -24/13 + 3

= -24/13 + 39/13

= 15/13
