Solve (x + 2 < 5) ∩ (x - 7 > -6). {all real numbers}
{x | 1 < x < 3}
{x | x < 3 or x > 1}

what is the original number? you forgot to add it.

the answer is d on edge

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
