Question

medal and fan.....please help

Answer 1

#1 is correct.

Answer 2

i know i just need help with the rest

Answer 3

Not sure about #2..let's look at #3.

\(\dfrac{3y - z}{y + 5z}\)

y = 6, z = 2

Plug in those values:

\(\dfrac{3(6) - 2}{6 + 5(2)}\)

Can you simplify that?

Answer 4

16
i did 6*3=18 then subtracted 2 to get 16
then the bottom 5*2 = 10 and then added 6 to get 16

16/16 = 16
is that right??

Answer 5

Um, yes, that's correct..but 16 / 16 doesn't equal 16..

Answer 6

oh

Answer 7

Divide that again, what do you get?

Answer 8

1

Answer 9

Yep, so that's your answer for #3.

Answer 10

okay thanks could u help me with 4 and 5 real quick?

Answer 11

Now for #4, we just plug in what we know into the formula.

\(A = \dfrac{1}{2} b h\)

\(A = \dfrac{1}{2} (18) (11)\)

Can you multiply 1/2 * 18 * 11?

Answer 12

99?

Answer 13

Yep, you got it, so that's our answer.

Answer 14

Okay, for #5,

How much is a nickel worth?

Answer 15

lol 5 cent

Answer 16

Yes, we write it like 0.05

So we have: 0.05n

Now how much is a dime worth?

Answer 17

0.10 or 0.1

Answer 18

Yes, so we have 0.10d

So our expression is:

0.05n + 0.10d

Answer 19

or 0.1d like you said :P
