Solve for x. -9x - 9 = x + 21

Mathematics

Nataly_w [17]3 years ago

Answer:

x=-3

Step-by-step explanation:

Original equation: -9x-9 = x+21

Add 9 to both sides: -9x=x+30

Subtract x from both sides: -10x=30

Divide by -10  on both sides: x=-3.

Let me know if this helps!

Answer:

x = -3

Step-by-step explanation:

1. add 9 to both sides -9x-9+9=x+21+9

2. simplify -9x=x+30

3. subtract x from both sides -9x-x=x+30-x

4. simplify -10x=30

5. divide both sides by -10 -10x/-10 = 30/-10

simplify and you're done!

Divide 5600 in the ratio 4 :5:7 <br>​
Elis [28]

Answer:

Step-by-step explanation:

So in our case, let assume 'x' as a common factor.

Thus,

4x + 5x + 7x = 5600;

16x = 5600;

x = 5600/16 = 350.

So,

4x= 350*4 =1400;

5x= 350*5 = 1750; &

7x= 350*7 = 2450.

Your answer is, 5600 = 1400+1750+2450 which is in ratio of 4:5:7.

Backgammon is a board game for two players in which the playing pieces are moved according to the roll of two dice. players win
Ivahew [28]

The rolls of the dice are independent, i.e. the outcome of the second die doesn't depend in any way on the outcome of the first die.

In cases like this, the probability of two events happening one after the other is the multiplication of the probabilities of the two events.

So, the probability of rolling two 6s is the multiplication of the probabilities of rolling a six with the first die, and another six with the second:

P(\text{rolling two 6s}) = P(\text{rolling a 6}) \cdot P(\text{rolling a 6}) = \dfrac{1}{6} \cdot \dfrac{1}{6}  = \dfrac{1}{36}

Similarly,

P(\text{rolling two 3s}) = P(\text{rolling a 3}) \cdot P(\text{rolling a 3}) = \dfrac{1}{6} \cdot \dfrac{1}{6}  = \dfrac{1}{36}

Actually, you can see that the probability of rolling any ordered couple is always 1/36, since the probability of rolling any number on both dice is 1/6:

P(\text{rolling any ordered couple}) = P(\text{rolling the first number}) \cdot P(\text{rolling the second number}) = \dfrac{1}{6} \cdot \dfrac{1}{6}  = \dfrac{1}{36}

How to answer the question
bulgar [2K]

That is sudoku, a game that I am really good at. first off the square on the left in the middle is messed up, because on the square above it there is a 5 where it would make the 5 in the middle left square incorrect. So you have to erase the 5 in the square on the middle left. Then if you can do sudoku, you could do the rest.

hope I helped!
