I'm assuming the equation is (2 * r) * (t - 3)... then you will just need to substitute the answers into the equation:
(2 * 2) * (6 - 3) = 4 * 3 = 12

Answer:
3n^2+9+5n^4+55n
Step-by-step explanation:
Steps
$\left(3n^2+9+5n^4-3n\right)+\left(-9n\left(-7\right)-5n\right)$
$\mathrm{Remove\:parentheses}:\quad\left(a\right)=a,\:-\left(-a\right)=a$
$=3n^2+9+5n^4-3n+9n\cdot\:7-5n$
$\mathrm{Add\:similar\:elements:}\:-3n-5n=-8n$
$=3n^2+9+5n^4-8n+9\cdot\:7n$
$\mathrm{Multiply\:the\:numbers:}\:9\cdot\:7=63$
$=3n^2+9+5n^4-8n+63n$
$\mathrm{Add\:similar\:elements:}\:-8n+63n=55n$
$=3n^2+9+5n^4+55n$
Answer:
87.04
Step-by-step explanation:
1lbs=16 ounces
5.44*16=$87.04 per ounce
she ran 2/3 mile in 1/6 hour, which means she ran 1/3 of a mile in 1/12 of an hour
so 1 mile would be run in 1/12 + 1/12+ 1/12 ( = 1/4 of an hour)
there are 4 quarters to an hour so she is running at 4 miles per hour
