Math ! explain the difference between finding the gcf and the lcm of variables.

Step-by-step explanation:

The GCF is the highest number that divides into two or more numbers. For example, the GCF between 24 and 36 is 12 because it is the largest number that both use when being divided or multiplied.

The LCM contrarily is the smallest number that divides into two or more numbers. Following the same example, the LCM between 24 and 36 is 2 because it's the smallest number used when multiplying or dividing to get to the two numbers.

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
