6 - 2x = 6x - 10x + 4
yarga [219]

6 - 2x = 6x - 10x + 4

6 - 2x =  - 4x + 4

6 =  - 4x + 4 + 2x

6 =  - 2x + 4

- 2x + 4 = 6

- 2x = 6 - 4

- 2x = 2

x =  \frac{ \:  \:  \: 2}{ - 2}

x =  - 1

Therefore , the value of x = -1

Answer:

  water

Step-by-step explanation:

Comparison of numbers can be done a couple of different ways. One way is to subtract one from the other. If the difference is positive, the minuend (first number) is the larger of the two.

Another way is to divide one number by the other. If the ratio is more than 1, then the numerator is the larger number.

For numbers in scientific notation, the division is perhaps the easiest. Here, that gives you ...

  \displaystyle\frac{\text{water mass}}{\text{oxygen mass}}=\frac{2.99\times10^{-26}\text{ kg}}{2.66\times10^{-26}\text{ kg}}=\frac{2.99}{2.66}\approx 1.12

This value is greater than 1, so the mass of a water molecule is greater.

__

You will note that the multipliers (10^-26 kg) cancelled because they were equal. If they are unequal, the usual rules of exponents apply.

The angles of a triangle are in an extended ratio of 5:7:3. What is the measure of the
uranmaximum [27]

Answer:

84°

Step-by-step explanation:

Let the measures of the triangle be 5x, 7x, 3x.

By interior angle sum postulate of a triangle.

5x + 7x + 3x = 180°

15x = 180°

x = 180°/15

x = 12°

7x = 7*12°= 84°

Measure of the largest angle = 84°
