i need help with both 9 and 10

Answers

Answer 1

I'll answer problem 9 to get you started

Answer: Choice (2) 3x-1 = 2x+3

===============================================

Explanation:

We will plug x = 7 into each equation or inequality given to us. Then we determine if we get a true statement or not.

----------------

Let's start with choice (1)

x + 3 > 6

7 + 3 > 6 .... x is replaced with 7

10 > 6

Since 10 is larger than 6, this makes the last inequality true. Therefore, the first inequality is true when x = 7. So we can rule out choice (1) since we are looking for a false statement.

----------------

Move onto choice (2)

3x-1 = 2x+3

3*7-1 = 2*7+3 ... replace every x with 7

21-1 = 14+3

20 = 17

This is false since we don't get the same number on each side. Therefore, choice (2) is the final answer.

----------------

Since we found the answer, we can stop here. But let's keep going to check the others.

choice (3)

2(x+1) = x+9

2*(7+1) = 7+9 ... plug in x = 7

2*(8) = 16

16 = 16

We get the same thing on both sides, so the equation is true. We can rule out choice (3).

-----------------

Now onto choice (4)

[tex]-2x + 10 \le 0\\\\-2*7 + 10 \le 0\\\\-14 + 10 \le 0\\\\-4 \le 0\\\\[/tex]

This is true since -4 is to the left of 0 on the number line, which makes -4 smaller than 0. We can rule out choice (4).

How many kilograms of rice will each person get if 6 people share 1-2 of a kilogram of rice equally?

Answers

Answer:

1/12

Step-by-step explanation:

So if a man has 1/2 kg of rice then he shares to 6 people equally.

So all you have to do is just take the total amount of rice then divide it to 6 people.

So 1/2 ÷ 6 equals to 1/12 in fraction form.

A baseball team will play 12 home games during the season. It has played 6 home games so far. Of the season's remaining games, 1/3 will be played at home. How many games, g, remain in the season?

Answers

Answer:18

Step-by-step explanation:

Total number of home games = 12

Number of played home games = 6

Hence,

Number of unplayed home games = 12 - 6 = 6

Let the number of remaining games be x

Of the remaining games, he will be playing 1/3 at home

This simply means that the number of unplayed home games will be 1/3 of the total remaining games

Now expressing this mathematically,

(1/3) * x = 6

By cross multiplication,

1 * x = 3 * 6

Hence, x = 18
