Answer:
-4 -23i
Step-by-step explanation:
(4-16i) - (8+7i)
Distribute the minus sign
4-16i -8-7i
Combine like terms
4-8 -16i -7i
-4 -23i
Answer:
<em>Plan A</em>
Step-by-step explanation:
Plan A -
$7 + 2.50(5)
$7 + $12.50
Plan A = $19.50
Plan B-
$4(5) = $20
Plan A is the cheapest, therefore it is the best plan.
Hope this helped! :)
Answer:
KL = 50
Step-by-step explanation:
∆JML is similar to ∆JNL. it follows that:
[tex] \frac{JM}{JN} = \frac{JL}{JK} [\tex]
JM = 4 + 20 = 24
JN = 4
JL = 10 + KL
JK = 10
Plug in the values
[tex] \frac{24}{4} = \frac{10 + KL}{10} [\tex]
[tex] 6 = \frac{10 + KL}{10} [\tex]
Multiply both sides by 10
[tex] 6*10 = \frac{10 + KL}{10}*10 [\tex]
[tex] 60 = 10 + KL [\tex]
Subtract 10 from each side
[tex] 60 - 10 = KL [\tex]
[tex] 50 = KL [\tex]
KL = 50
That depends on the total distance of the race, which you
have not bothered to mention.
If the team has exactly enough runners to run the entire race,
one at a time, then the number of runners needed is ...
(3) times (the total distance of the race, in miles) .
