statuscvo [17]4 years ago
7 0

Answer:

There is one solution.

x = -17

<em>Proof and step-by-step explanation:</em>

Step 1: <em>Add the numbers</em>

3x-7 = 4+6+4x

3x-7 = 10+4x

Step 2: <em>Move</em><em> </em><em>terms</em>

3x-7 = 10+4x

3x-4x = 10+7

Step 3: <em>Collect the like terms and calculate the sum</em>

3x-4x = 10+7

-x = 17

Step 4: <em>Change the sign by multiplying both sides by -1</em>

-x (×-1) = 17 (×-1)

x = -17

I hope this helped ! :)

Zielflug [23.3K]

Answer:

Profit % is 1.94% .

Step-by-step explanation:

The CP of both VCR and TV were same that is Rs 78,000 . So ,

=> CP \ of \ the \ buyer \ = \ Rs78,000 \times 2 = Rs 156,000

As per Question , on one he made a loss of 4% and profit of 8% on the other .

And , the net SP would be ,

=> Total \ SP \ = \ \dfrac{96}{100}\times Rs 78,000 + \dfrac{108}{100}\times Rs 78,000 \\\\=> Total\ SP = Rs 74,800 + Rs 84240 \\\\\boxed{\red{\bf => Total \ SP= Rs 159,040 }}

<u>So , here clearly SP > CP . So , there's a profit .Hence profit % would be </u><u>:</u><u>-</u>

=> Profit \% = \dfrac{ SP - CP }{CP}\times 100 \\\\=> Profit \% = \dfrac{Rs 159,040-Rs156,000}{Rs156,000}\times 100 \\\\=> Profit\% = \dfrac{3040}{156000}\times 100 \\\\\underline{\blue{\bf => Profit\% = 1.94 \% }}

An empty can weighs 30 grams. The weight of the same can filled with liquid is 47.3 grams. Which equation could be used to find
Alika [10]

Answer:

w = y - x is the equation to find w

Where,

w = Weight of the liquid

x = Weight of the empty can

y = Weight of the can with liquid

Step-by-step explanation:

Let

Weight of the empty can = x

Weight of the liquid = w

Weight of the can with liquid = x + w = y

x= 30 grams

w = ?

y= 47.3 grams

y = x + w

w = y - x

= 47.3 - 30

= 17.3

w= 17.3 grams

Therefore, the weight of the liquid is 17 .3 grams
