In terms of the δe values, which are the two expressions for the difference in internal energy between state a and state b? check all that apply. check all that apply. δeab=δe3+δe4 δeab=δe2+δe3 δeab=δe1+δe4 δeab=δe1−δe2 δeab=δe1+δe2 δeab=δe3−δe4 δeab=δe1+δe2+δe3+δe4

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

i dont know

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
