The value would be $13200 because
1 mile = 5280 inches
5280 times 2 1/2 = 13200
Answer:
Step-by-step explanation: what exactly are you asking?
Properties:
1) a+ b = b+a Commutative
2) (a + b) + c = a + (b+c) Associative
3) a(b+c) = ab + ac Distributive
Here we are given
11 + (19 + 6) = (11 +___) + 6
The number 19 is missing on the right.
So we have
11 + (19 + 6) = (11 +19) + 6
This looks like Property 2 above.
Hence it is associative property.
$45 per plumber hour (p)
$25 per assistant hour (a)
$4035 = 25a + 45p
p = 2a
4035 = 25a + 45(2a)
4035 = 25a + 90a
4035 = 115a
a = 35.086 hours
p = 2(35.086)
p = 70.174 hours
The plumber worked about 70 hours, and his assistant worked about 35 hours.
