Tom's school report must be more than 12 pages, he writes at the rate of a half a page a day.
soldi70 [24.7K]

Answer:

24 days (or more)

Step-by-step explanation:

I assume you want to figure out how long it will take Tom to write the minimum amount of pages for his school report at that rate?

Since Tom writes 1/2 a page a day and he must write 12 or more pages, then it will take him 2 days to write one page, thus, 24 days to write 12 pages.

Therefore, Tom needs at least 24 days to write his school report.

3. x + 4y = 30<br> x - 2y = 0
kolbaska11 [484]

Answer:

Step-by-step explanation:

Given that:

x + 4y = 30

x - 2y = 0

Subtracting both equations:

6y = 30

y = 30/6

y = 5

Putting in above equation

x + 4(5) = 30

x + 20 = 30

x = 10

Isolate the variable by dividing each side by factors that don't contain the variable.

x= 13/4 - y/4



If you are solving for x (only)
X = 45/4 - y/4

If you are solving for y (only)
Y= 45- 4x
