Answer:

2 =x

Step-by-step explanation:

2 - 4x = 3x - 12

Add 4x to each side

2 - 4x+4x = 3x+4x - 12

2 = 7x-12

Add 12 to each side

2 +12 = 7x - 12+12

14 = 7x

Divide each side by 7

14/7 = 7x/7

2 =x

Answer:

x = 2

Step-by-step explanation:

Step 1: Write out equation

2 - 4x = 3x - 12

Step 2: Add 4x on both sides

2 - 4x + 4x = 3x + 4x - 12

2 = 7x - 12

Step 3: Add 12 on both sides

2 + 12 = 7x - 12 + 12

14 = 7x

Step 4: Divide both sides by 7

14/7 = 7x/7

2 = x

Step 5: Rewrite

x = 2

A company that manufactures hair ribbons knows that the number of ribbons it can sell each week, x, is related to the price p pe
mel-nik [20]

Given:

The number of ribbons it can sell each week, x, is related to the price p per ribbon by the equation:

x=1000-100p

To find:

The selling price if the company wants the weekly revenue to be $1,600.

Solution:

We know that the revenue is the product of quantity and price.

R=xp

R=(1000-100p)p

R=1000p-100p^2

We need to find the value of p when the value of R is $1600.

1600=1000p-100p^2

1600-1000p+100p^2=0

100(16-10p+p^2)=0

Divide both sides by 100.

p^2-10p+16=0

Splitting the middle term, we get

p^2-8p-2p+16=0

p(p-8)-2(p-8)=0

(p-8)(p-2)=0

Using zero product property, we get

p-8=0 or p-2=0

p=8 or p=2

Therefore, the smaller value of p is $2 and the larger value of p is $8.

a hiker descends from a mountain peak. if the hiker descends at a rate of 700 ft every half hour, what is the hikers elevation r
Margarita [4]
If the hiker covers 700 feet every 30 minutes. In an hours time the hiker is 1400 feet relative to the peak of the mountain. 30 minutes later which is actually 1 hrs 30 minutes later the hiker is 1400 + 700 = 2100 feet relative to the peak of the mountain. In another 30 minutes time (now 2 hours later) the hiker is 2100 + 700 = 2800 feet relative to the mountain peak. 30 minutes later (now 2hr 30 minutes) hiker is 2800 + 70. = 3500 feet and so in 3hrs time the hiker is 3500 + 700 = 4200 feet relative to the peak of the mountain.

The ratio of the amount of ch milk syrup to the amount of ch milk dairy is 2:7 how manny gallons of milk are you needed for 32 g
Pavel [41]
The question is worded kind of unclearly, but I will do what I can. If you are trying to figure out how much milk you can make with 32 gallons of syrup, it would be 16 since 32/2 is 16. If you are trying to figure out how much dairy is needed, then it would be 112 because 32/2 is 16, and 7(16) is 112. I hope this helped!
