Alex Ar [27]

2400 inches or 2000 feet is the correct answer

there are 60 minuets in an hour, and 10 sets of 6 minuets, so you multiply 5 by ten to get 50

then you multiply 50 by 48 to get 2400

then you divide by 12 to get 2000 feet

5. Simplify the expression and find its value when p= 4 and q = -5:
Ierofanga [76]
  • <u>Answer</u>: -180

Step-by-step explanation:

\bf   \blue{ \boxed{  \bf p = 4 \:  \: and \:  \: q =  - 5 \Rightarrow pq = 4 \times ( - 5) =  - 20}}

3(p2q + pq2 - pq) - 6pq + 3pq2 =

3[-20 × 2 + (-20) × 2 - (-20)] - 6 × (-20) + 3 × 2 × (-20) =

3[-40 + (-40) + 20] - 6 × (-20) + 3 × 2 × (-20) =

3(-40 - 40 + 20) - 6 × (-20) + 3 × 2 × (-20) =

3(-80 + 20) - 6 × (-20) + 3 × 2 × (-20) =

3 × (-60) - 6 × (-20) + 3 × 2 × (-20) =

-180 + 120 + 6 × (-20) =

-180 + 120 + (-120) =

-180 + 120 - 120 =

-60 - 120 = -180
