Since Kirk starting reading on Saturday, I can make an equation of 20 + 20d. The equation for Lito is 20d. Therefore, the system of equations is 20 + 20d = 25d.
I can solve this like any other equation. Firstly, I can subtract 20d on the left hand side to give me 20 = 5d. Then, I can divide by 5. This gives me 4 = d, or d = 4. This means that it takes Lito 4 days to catch up. I can then multiply 20 * 4 and 25 * 4 to give me 100 pages.
The system of equations is 20 + 20d = 25d, and the amount of pages they each read is 100.
Answer:
It is 0.873 but rounded to hundredth is 0.87
Step-by-step explanation:
so so sorry if this is wrong
29 stacks x 4cards. 29x4= 116
one way to do this is to convert each fraction to same denominator ( the LCD)
Well we can eliminate -3/5 because its negative so 4/7 is definitely > -3/5.
4/7 = 16/28 and 3/4 = 21/28
so 4/7 < 3/4
Therfore 4/7 does lie between the 2 fractions
