Answer:

Infinite number of solutions

Step-by-step explanation:

5(x+2)=5x+10

5x+10=5x+10

If they are equal on both sides then it is going to infinite number of solutions

You could use the number 5 to support your answer

5(5+2)=5(5)+10

25+10=25+10

35=35

You could use the number 1 to support your answer

5(1+2)=5(1)+10

5+10=5+10

15=15

you bought 5 chocolate bars and 8 blow pops for $23.25 your sister bought 2 chocolate bars and 13 blow pops for 21.55 how much d
kirza4 [7]

Answer:

  • $2.65

Step-by-step explanation:

Let chocolate bar = c and blow pops = b

<u>As per given we have equations below:</u>

  • 5c + 8b = 23.25
  • 2c + 13b = 21.55

<u>13 times the first equation minus 8 times the second to eliminate b and find c:</u>

  • 13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55)
  • 65c - 16c = 129.85
  • 49c = 129.85
  • c = 129.85/49
  • c = 2.65

Each chocolate bar costs $2.65

Is the following statement a good definition? Why? An integer is divisible by 100 if and only if its last two digits are zeros.
kifflom [539]
The given statement is:
An integer is divisible by 100 if and only if its last two digits are zeros

The two conditional statements that can be made are:

1) If an integer is divisible by 100 its last two digits are zeros.

This is a true statement. If a number is divisible by 100, it means 100 must be a factor of that number. When 100 will be multiplied by the remaining factors, the number will have last two digits zeros. 

2) If the last two digits of an integer are zeros, it is divisible by 100.

This is also true. If last two digits are zeros, this means 100 is a factor of the integer. So the number will be divisible by 100.

Therefore, the two conditional statements that are formed are both true.

So, the option A is the correct answer.
Yes, it is. When the definition is separated into two conditional statements, both of the statements are true

Elza [17]

Answer:

Step-by-step explanation:

Let total money be m

Then, the money spent on 2 video games is 1/5m

<u>Each game costs:</u>

  • 1/5m ÷ 2 =
  • 1/10m

So each video game costs 1/10 of birthday money
