C=3

9c minus 6c is 3c
3c minus 2c is 1c or c
c plus 5c is 6c

Answer: c = 3

Step-by-step explanation: First, make sure you simplify the left side of the equation by combining our <em>c terms</em> together.

So we have 9c - 6c - 2c + 5c which simplifies to 6c.

So now we have the equation 6c = 18.

To solve for <em>c</em> in this equation, we want to get <em>c</em> by itself on the left side of the equation. Since <em>c</em> is being multiplied by 6, to get <em>c</em> by itself, we need to divide by 6 on the left side of the equation. Since we divided by 6 on the left side, we must also divide by 6 on the right side.

On the left side, the 6's cancel out so we're simply left with <em>c</em>. On the right side we have 18 divided by 6 which is 3 so we have <em>c = 3</em>.

Which is the correct way to represent 0.0035 kg by using scientific notation? –3.5 103 kg –3.5 10–3 kg 3.5 10–3 kg 3.5 103 kg?
Vlada [557]
It would be

3.5 × 10⁻³ kg.

The decimal point must be moved 3 places to the right in order to have it behind the first non-zero digit; this gives us the exponent of 3, and since we are moving the decimal to the right, it is a negative exponent.

choli [55]

Answer:

Step-by-step explanation:

x+y=10

x=10-y

x=10-5

x=5

3y= -3x+30

3(10-y)= -3(10-y)+30

30-3y= -30+3y+30

30+30-30=6y

30=6y

y=5
