Hello,
Let's
V1 the velocity of the 1st bricklayer,
V2 the velocity of the 2nd bricklayer,
1wall=V1*6==>V1=w/6
1wall=V2*4==>V2=w/4
==>V1+V2=w/6+w/4=10w*24=5w/12
Let's t the time for the 2 bricklayer to build the wall
(V1+V2)t=w
==>5w/12*t=w
==>t=12/5 (h)=2h24min.
Some of the rates that can be formed are; Speed = 8.333 mph
Number of miles covered per gallon of gasoline used = 14.706 mpg
The number of gallons used per hour = 0.567 gallons per hour

We are told that the Northwest Football team drove 25 miles.
Now, the time that this team took was 3 hours.
Thus, one rate that can be formed is the speed in mi/hr. Thus;
Speed = 25/3 = 8.333 mph
Another rate that can be found is the number of miles covered per gallon of gasoline used. This gives us;
25/1.7 = 14.706 mpg
Another rate that can be gotten is the number of gallons used per hour;
= 1.7/3 = 0.567 gallons per hour

Because if you divide 34 by 2 you get 17. Then subtract 17 minus 5 which equals 12 so you multiply 12 times 2 for Janos' age and 12 times 3 for David's age which makes 60 but not 61. Their present age is 17.
Step-by-step explanation: Substitute the numbers in for x to find the y - intercept
A) 1:
3y = 6x + 12
3y = 6(1) + 12
3y = 6 + 12
<u>3y = 18</u>
3 3
y = 6
B) 2:
3y = 6x + 12
3y = 6(2) + 12
3y = 12 + 12
<u>3y = 24</u>
3 3
y = 8
C) 3:
3y = 6x + 12
3y = 6(3) + 12
3y = 18 + 12
<u>3y = 30</u>
3 3
y = 10
D) 4:
3y = 6x + 12
3y = 6(4) + 12
3y - 24 + 12
<u>3y = 36</u>
3 3
y = 12
Hope this helps you!!! :)
