280 + (-22)

5 answers

280 + (-22) equals 258.

280 + (-2t)
(T = 20)

To solve the expression \(280 + (-2t)\) with \(t = 20\):

  1. Replace \(t\) with 20: \[ 280 + (-2 \cdot 20) \]

  2. Calculate \(-2 \cdot 20\): \[ -2 \cdot 20 = -40 \]

  3. Now substitute that back into the expression: \[ 280 + (-40) \]

  4. Finally, calculate: \[ 280 - 40 = 240 \]

So, \(280 + (-2t)\) when \(t = 20\) equals \(240\).

280 + (-2t)
(T = 4)

To solve the expression \(280 + (-2t)\) with \(t = 4\):

  1. Substitute \(t\) with \(4\): \[ 280 + (-2 \cdot 4) \]

  2. Calculate \(-2 \cdot 4\): \[ -2 \cdot 4 = -8 \]

  3. Now substitute that back into the expression: \[ 280 + (-8) \]

  4. Finally, calculate: \[ 280 - 8 = 272 \]

So, \(280 + (-2t)\) when \(t = 4\) equals \(272\).
