on tuesday norachai bought seven boxes. on wednesday half of the boxes that he had were destroyed. on tuesday there were only 13 left. how many did he have on monday?
Answer:
19
Step-by-step explanation:
First you figure out x/2=13
Then you find out x=26
So then you figure out x+7=26
Which is then x=19
The number of boxes Norachai had on Monday is 19 boxes.
Given that, on Tuesday Norachai bought seven boxes.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of boxes had on Monday be x.
Now, the number of boxes had on Tuesday
= x+7
Now, on Wednesday half of all the boxes that he had were destroyed
= (x+7)/2
As, given on Thursday he had left boxes = 13
So, (x+7)/2 = 13
⇒ x+7=26
⇒ x=19 boxes
Therefore, the number of boxes Norachai had on Monday is 19 boxes.

Alisa and Chelsea paid a total of $31 to rent a canoe. Write
and solve an equation to find h, the number of hours they
rented the canoe.
Answer:
6+ 10h =31
Step-by-step explanation:
That's your equation. You have to then subtract six from the six and 31. Which would get you 10h=25. Divide 10 from both sides and get h=2.5. They rented a canoe for 2 and a half hours.

write an equation in slope- intercept form of each line
Answer:
Use the slope −2 and the point (−4,−5) to find the y-intercept.
y=mx+b
⇒−5=(−2×−4)+b
⇒−5=8+b
⇒b=−13
Write the equation in slope intercept form as:
y=mx+b
⇒y=(−2)x−13
Hence, the equation of the line is y=−2x−13.
