A restaurant requires 4 1/2 ounces of butter for every bowl of curry it makes. In an hour an average of 2 1/2 bowls of curry is served.How many ounces of butter are required in 1 1/2 hours?


ounces

Enter a number like 212or 52.

Answers

1 Ounce of Butter = B

Bowl of Curry = C

1 Hour = H

----------------

A restaurant requires 4 + 1/2 ounces of butter for every bowl of curry it makes...

C = 9/2 * B

In an hour, an average of 2 + 1/2 bowls of curry is served...

H = 5/2 * C

... Which means that: H = 5/2 * 9/2 * B

... So: H = 45/4 * B

The question was: How many ounces of butter are required in 1 + 1/2 hours?

Here is the answer:

3/2 * H = 3/2 * 45/4 * B

3/2 * H = 135/8 * B

In words, 16 + 7/8 ounces of butter would be required over a period of 1 + 1/2 hours.

What is -4x+8=48 what is x

Answers

Subtract 8 from each side:

-4x = 40

Divide each side by -4 :

x = -10
X= -10

-4x+8=48

Subtract 8 on both sides so it would be -8

Then rewrite the equation and it should be

-4x/-4 = 40/-4

Which equals -10

All you have to do is replace the n in 8n with the sequance number you're looking for
like for instance:
8(1)=8
8(2)=16
a_n=8n\n \na_1=8\cdot1=8\na_2=8\cdot2=16\na_3=8\cdot3=24\na_4=8\cdot4=32\na_5=8\cdot5=40
