Question

:3

Answer 1

do you have any guesses?

Answer 2

Yeah, sorta

Answer 3

this seems like questions to make you familiar to the basics of algebra, so it would not do much good if i just gave you the answers straight away as you'd struggle the rest of the year. So it's important you at least try to understand these assignments

Answer 4

For the first one, you know that Dirk worked h hours, and that Charlie worked 1.5 hours less than Dirk. So the amount they work together is h + (h-1.5), right? And the total number of hours they work together is 25. So what is the answer to the first one?

Answer 5

can you at least tell me which ones you have already an answer to, and why you think that answer is correct?

Answer 6

no 1 is not D. Dirk works h hours and his friend works 1.5 hours less than Dirk, so his friend works h - 1.5. You have that his friend works 1.5 hours more andd that is incorrect. 1 is C.

Answer 7

ohh ok

Answer 8

how about 2?

Answer 9

Close call, i think your reasoning was largely correct but the (h+1.5) or (h-1.5) represents Charlie, as Dirk is already represented by the h. And since Charlie works less than dirk, it should be the one with the -

Answer 10

\( \color{red}{Dirk}~ \color {green} {Charlie}~\color{blue}{total}\)
\( \color{red} {h} + \color{green}{(h – 1.5)} = \color{blue}{25}\)

Answer 11

as for 2, the quotient of a number means a division. so an unknown number divided by 3 totals 18

Answer 12

k dudee i need help on the others i have 10 minutes my brother wrote this test for me and i get to borrow his skateboard for a week if i get them all correct..

Answer 13

oh i forgot to include the 8 less part, so an unknown number divided by 3 minus 8 equals 18

Answer 14

Answer 20

15 = 3x, as it's the only one with multiplication

Answer 28

5. The length of a rectangle is 4 inches longer than its width. The area of the rectangle is 12 square inches. What are the length and width? Which equation models this problem?
4 x w = 12
w(4 + w) = 12
w + (4 + w) = 12
w – (4 + w) = 12

Answer 29

okay dude please hurry i got 2 min what do you think 4 and 5 are?
