In this problem, you combine the like terms...

4a - 3b + 7a

4a and 7a are like terms so you add them together.

4a + 7a = 11a

It cost $5 for his brother's ticket.

Step-by-step explanation:

Let,

Micheal's ticket price= x

His brother ticket price = y

According to given statement;

x+y=12    Eqn 1

y = x-2    Eqn 2

Putting value of y from Eqn 2 in Eqn 1

x+(x-2)=12\\x+x-2=12\\2x=12+2\\2x=14\\

Dividing both sides by 2;

\frac{2x}{2}=\frac{14}{2}\\x=7

Putting x=7 in Eqn 2

y=7-2\\y=5

It cost $5 for his brother's ticket.

Please help with this question. I need an answer ASAP!! I need help! I don't understand this!
Romashka-Z-Leto [24]

Answer: 42°

<u>Step-by-step explanation:</u>

HJ is an angle bisector of ∠IHK so

∠IHJ ≅ ∠KHJ ⇒ m∠IHJ = m∠KHJ

                           3a + 6 = 5a - 18

                                   6  = 2a - 18

                                  24 = 2a

                                   12 = a

∠IHJ = 3a + 6

        = 3(12) + 6

        = 36 + 6

         = 42
