Brenda bought a new computer for $380. She made a payment of $140 and got a discount of $30. Her mother paid one half
of the balance. How much does Brenda have left to pay?

I got 105

Step-by-step explanation:

$380 - $140 = $240. $240 - $30 discount = $210. $210 ÷ the ½ her mom paid = the $105 that Brenda still has to pay.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
