Answer:

1900

Step-by-step explanation:

1 kg = 1000g

1.2kg = x

<u>1</u><u> </u><u>kgx</u> = <u>1</u><u>2</u><u>0</u><u>0</u><u> </u><u>kg.g</u>

1kg. 1kg

x = 1200 g

1 decagram = 10g

40 decagram = x

<u>1</u><u> </u><u>dg.x</u> = <u>4</u><u>0</u><u>0</u><u> </u><u>dg.g</u>

1 dg. 1 dg

x = 400g

so the total= 1200g +300 + 400g=1900g

without the unit = 1900

Jacks mother gave him 50 chocolates to give to his friends for his birthday party. He gave 3 chocolates to each of his friends a
labwork [276]

Answer:

3x+2=50

There are 16 friends at Jack's party.

Step-by-step explanation:

Please consider the complete question.

Jack's mother gave him 50 chocolates to give to his friends at his birthday party. He gave 3 chocolates to each of his friends and still had 2 chocolates left. Write an equation to determine the number of friends (x) at Jack's party. Find the number of friends at Jack's party.  

Since there are x friends at party, so chocolate given to x friends would be 3 times x (3x) because Jack gave 3 chocolates to each friend.

As Jack has 2 chocolates left after giving to his friends, so total numbers of chocolates would be 3x+2.

Now we will equate total number of chocolates by 50 as:

3x+2=50

Therefore, the equation 3x+2=50 can be used to find number of Jack's friends.

Let us solve for x.

3x+2-2=50-2

3x=48

\frac{3x}{3}=\frac{48}{3}

x=16

Therefore, there are 16 friends at Jack's party.

Solve x + 5 = 10 thank you
jonny [76]

Answer:

x = 5

Step-by-step explanation:

Step 1: Subtract 5 from both sides.

  • x + 5 - 5 = 10 - 5
  • x = 5

Step 2: Check if solution is correct.

  • 5 + 5 = 10
  • 10 = 10

Therefore, x = 5.
