Answer: There are 7 crayons in each box.
Step-by-step explanation: First, the most difficult part is coming up with the equation. You know that she has a total of 59 since it mentioned “a collection of 59 crayons”. Then you also know there are 17 crayons on the side, so you can subtract 17 from 59, the total (which is now 42). Then you have 6x. 6 is for the number of boxes and x is for the unknown number of crayons found in each box. Then you can just simply solve after identifying each factor of the equation.
The way to find an unknown is to isolate it.
n+14(-14)=15(-14)
n=1
Then we can check our answer by plugging it into the equation.
1+14=15
15=15
So n=1.

Answer:
150 kL glutinous rice
300 kL ordinary rice
Step-by-step explanation:
Each half of the property is 3 ha/2 = 1.5 ha.
For the transplanted glutinous rice, John needs ...
(100 kL/ha)·(1.50 ha) = 150 kL
For the broadcast ordinary rice, John needs ...
(200 kL/ha)·(1.50 ha) = 300 kL
Answer:
x = 5/9
Step-by-step explanation:
1/3 +x = 8/9
We need to get a common denominator of 9
1/3 * 3/3 +x = 8/9
3/9 + x = 8/9
Subtract 3/9 from each side
3/9 - 3/9 +x = 8/9 - 3/9
x = 5/9
