3e. 5*(3*2)=(5*3)*2
3f. 4+0=4
3g. 6*1=6

4. using the formula r=d/t, where d is distance in miles, r is rate, t is time in hrs, at which rate must you travel to cover 252mi in 4.5hrs? explain.

Answer 1

That's alot of questions.

Answer 2

You don't know how to do any of them?

Answer 3

Answer 5

"4. using the formula r=d/t, where d is distance in miles, r is rate, t is time in hrs, at which rate must you travel to cover 252mi in 4.5hrs? explain.
so,
d = 252
t = 4.5
then
r = 252/4.5

Answer 6

thankyou so much can yu help me with any of the others?

Answer 7

"2.order the numbers from least to greatest: -1/6, -0.3, squareroot of 1, -2/13, 7/8

put the fractions into decimals, then order the fractions based on the values of the decimals
-1/6 = -0.166
-0.3 = -0.3
squareroot of 1 = 1
-2/13 = -0.1538
7/8 = .875

Answer 8

so, 0.1538, .875, 0.166, 0.3, and 1 ?

Answer 9

don't forget the negative signs, try again tho

Answer 10

is .875 less than .166? noh, so you gotta swap those around

Answer 11

i dont know :(

Answer 12

okay, i think i got it thanks

Answer 13
