Answer:
Part a) Daniel's age is 2 years
Part b) Kevin's age is 8 years
Step-by-step explanation:
<u><em>The question is </em></u>
Part a) How old is Daniel?
Part b) How old is Kevin?
Let
x ----> Kevin's age
y ----> Daniel's age
we know that
-----> equation A
----> equation B
Equate equation A and equation B
![4y=y+6](https://tex.z-dn.net/?f=4y%3Dy%2B6)
solve for y
![4y-y=6](https://tex.z-dn.net/?f=4y-y%3D6)
![3y=6](https://tex.z-dn.net/?f=3y%3D6)
![y=2](https://tex.z-dn.net/?f=y%3D2)
therefore
Daniel's age is 2 years
<em>Find the value of x</em>
substitute the value of y in any of the two equations
![x=4(2)=8\ years](https://tex.z-dn.net/?f=x%3D4%282%29%3D8%5C%20years)
![x=2+6=8\ years](https://tex.z-dn.net/?f=x%3D2%2B6%3D8%5C%20years)
therefore
Kevin's age is 8 years
Answer:

Answer: 40 minutes
Step-by-step explanation:
It takes 16 minutes for the first 2 stations to water their sections which means that the time taken per station is:
= 16/2
= 8 minutes per station
Ms. Reynolds has 5 stations.
Total time taken will therefore be:
= 8 * 5
= 40 minutes
Answer:
Independant = onions wight. Dependent = cost.
Step-by-step explanation: The Cost depends on how much the onions weight.
I assume that you want the measurement of angle A
A + (A + 38) = 90
angle A + (38 more than angle a) = are complementary
2A = 52
A = 26
