N-2=10n+4 over 2 what is the value of n

Mathematics

Snowcat [4.5K]3 years ago
6 0

Consider the given equation:

n-2 = \frac{10n+4}{2}

Cross multiplying in the given equation, we get

(n-2) \times 2 = 10n+4

Applying distributive property which states a(b+c) = ab+ac, we get

(n \times 2) - (2 \times 2) = 10n+4

2n -4 = 10n+4

Adding '4' on both the sides, we get

2n-4+4 = 10n+4+4

2n = 10n+8

Subtracting '10n' from both the sides of the equation, we get

2n-10n = 10n+8-10n

-8n = 8

Dividing by '-8' in both the sides of the equation, we get

n= -1

Therefore, the value of 'n' is -1.

A supplies box contains 3 red crayons, 2 green crayons, and 6 blue crayons. If we choose a crayon, then another crayon without p
wel

Answer:  3/11 & 6/10

Step-by-Step explanation:

there are 11 crayons, 3 of which are red so the chance of picking a red one is 3 out of 11. now that you have taken out a crayon you take the original number and take away 1

11 - 1 = 10

so the chance of taking a blue canyon out is 6/10.

these events are dependent because if you didn't take the first crayon out of the supply box the answer would be 6/11 instead of the 6/10 we have

Write the expanded form of the decimal 0.082¯ using powers of 10
Softa [21]

Answer:

0.082 = 8.2× 10^-2

Step-by-step explanation:

Given the decimal number 0.082, the expanded form using the power of 10 can be gotten by writing the decimal number in standard format(writing as a multiple of 10).

To do that we will shift the decimal point to the front up to the front of digit 8. This shows that the decimal point will be shifted 2times to the front. Since of is shifted 2times to the front, our power of 10 will be -2.

0.082 = 8.2× 10^-2

This gives the required answer.

Note that, the power of 10 is positive when decimals are shifted to the back and negative when shifted to the front(in this case).
