29 — 6x=5(1 – 6x)<br> Please show me the steps
Lady bird [3.3K]

Answer:

x= -1

Step-by-step explanation:

<u><em>START</em></u> 29 - 6x = 5(1 - 6x)

1.  Distribute

29 - 6x = 5 - 30x

2. Isolate the variable

~ <u>2a</u>. Add 30x to both sides

29 - 6x + 30x = 5 - 30x + 30x

~ <u>2b</u>. Subtract 29 from both sides

29 - 29 - 6x + 30x = 5 - 29 - 30x + 30x

3. Simplify

24x = -24

4. Solve

x = -1

<em><u>END</u></em>

Three ounces of cinnamon cost 2.40. If there are 16 ounces in 1 pound, how much does cinnamon cost per pound?
BartSMP [9]
To find how much cinnamon per pound you first divide the $2.40 by the 3 oz to find how much per ounce...so $2.40/3 = 80 cents. Then u multiply that by the 16 oz to get the amount for 1 pound...so .80x16= $12.80 per pound.
Hope it helps!
