\frac{5(2k - 3)-3(k + 4)}{3k+2}

  • Substitute -2 for k into the expression.

\frac{5[2(-2) - 3]-3[(-2) + 4]}{3(-2)+2}

  • Solve inside the parentheses first.
  • Multiply 2 * (-2) in the first parentheses, and add (-2) + 4 in the second parentheses. Multiply 3 * (-2) on the bottom.

\frac{5(-4 - 3) - 3(2)}{-6+2}

  • Solve inside the first parentheses.
  • Add -6 + 2.

\frac{5(-7) - 3(2)}{-4}

  • Multiply 5 * (-7) and 3 * (2).

\frac{(-35) - (6)}{-4}

  • Subtract -35 and 6.

\frac{(-41)}{-4}

  • -41/-4 is the same as 41/4, and 41/4 cannot be simplified further, so:
<h3>Your answer is 41/4.</h3>

Is the following statement a good definition? Why? An integer is divisible by 100 if and only if its last two digits are zeros.
nikitadnepr [17]

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 the last two digits zeros.

<h3>What happen when last two digit of the number are 0?</h3>

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

This is also true. If the 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, option A is the correct answer.

Yes, it is. When the definition is separated into two conditional statements, both of the statements are true.

−23−(−113) i think it is -2/3
dangina [55]
-23-(-113)
Subtract -113 from -23. This would also be the same as adding 113 to -23 because the two negative signs are equal to one positive sign.
