After 7 years you will have about 3,500
2x-2+x+3+x+11=180
4x+12=180
4x= 168
X= 45
Answer:
Dividing is the same as putting numbers into a fraction. This is N/8. We don't get the answer until we figure out what N is equal to.
Okay so the value of X is 9x^2/7
9514 1404 393
Answer:
18
Step-by-step explanation:
90 = 18·5
126 = 18·7
180 = 18·10
990 = 18·55
The greatest common factor of these numbers is 18.

<em>Comment on the GCF</em>
It can be useful to know Euclid's algorithm for finding the GCF:
- Determine the remainder from dividing the larger number by the smaller.
- If the remainder is zero, the smaller number is the GCF. If the remainder is non-zero, use it to replace the larger number and repeat from step 1.
For example, 126 mod 90 = 36; 90 mod 36 = 18; 36 mod 18 = 0, so 18 is the GCF of 126 and 90. (The modulo function 'mod' returns the remainder from division.)
