Answer:
3 hours and 20 minutes
Step-by-step explanation:
Jack's rate is 1 puzzle for every 5 hours, so his rate per hour is 1/5 of a puzzle per hour.
We need to find the rate of his brother so here is our equation,
1/5 + 1/x = 1/2
1/2 - 1/5 =1/x
3/10 = 1/x
3/ 3x = 3/10
3x=10
x= 3 and 1/3 hours
3 hours and 20 minutes
Answer:
Option B
Step-by-step explanation:
For this we'll put all of these options in place of x
<u><em>Number 1:</em></u>
=> 
=> 2(4)+14-4
=> 8+10
=> 18
<u><em>So, This is not the zero of the polynomial</em></u>
<u><em>Number 2:</em></u>
=> 
=> 2(1/4)+7/2-4
=> 1/2+7/2-4
=> 
=> 
=> 0
<em><u>Yes, This is the zero of the polynomial having zero as an answer</u></em>
<em>So, We'll end the solution here because we have found the zero of the polynomial.</em>
Hope this helps :)

Y = 60x +150
we put our ^0 mph as our Multiplier os x and since Alfred already traveled the 150 miles... that is just added on.
The Matchup are:
1. 1/3(24+15)=1/3•24+1/3•15 - distributive property
2. 101+(29+417) = (101+29) + 417 - associative property of addition.
3. (-14)+81 = 81 + (-14) - commutative property of addition.
4. -72 +0=-72 - additive identity.
5. 13/17•17/13=1 -multiplicative inverse.
<h3>What is a distributive property?</h3>
The distributive Property is one that connote the fact that if a factor is said to be multiplied by the sum or the addition of two terms, it is vital to multiply all of the two numbers by using the factor, and lastly carry out the addition operation.
Hence, The Matchup are:
1. 1/3(24+15)=1/3•24+1/3•15 - distributive property
2. 101+(29+417) = (101+29) + 417 - associative property of addition.
3. (-14)+81 = 81 + (-14) - commutative property of addition.
4. -72 +0=-72 - additive identity.
5. 13/17•17/13=1 -multiplicative inverse.
