kumpel [21]

1/7 gallon = 1 batch

[multiply by 7 through]
1 gallon = 7 batches

[multiply by 8/9 through]
8/9 gallon = 7 x 8/9
8/9 gallon = 6 2/9

[Good enough to make 6 batches, not enough to make 7 batches]

So he can make 6 batches of collard green

How do you combine like terms of -8(r-2) + 6(r-2) ??? Will mark brainliest if the answer is right.

solmaris [256]

Answer:

$-2r+4$

Step-by-step explanation:

$-8(r-2)+6(r-2)$

Distribute:

$(-8)(r)+(-8)(-2)+(6)(r)+(6)(-2)\\-8r+16+6r+-12$

Combine like terms:

$(-8r+6r)+(16+-12)\\-2r+4$

-2r + 4 is your answer.

What ratio is equivalent to TanA?

USPshnik [31]

Answer:

24/10

Step-by-step explanation:

From the diagram

Opposite BC = 24cm

Adjacent = AC = 10cm

tan theta = opposite/adjacent

Substitute

tan <A = BC/AC

tan <A = 24/10

Hence the equivalent ratio is 24/10
