Answer:
a = - 25
Step-by-step explanation:
Given that:
4a+6+16=-9(2+12a)-10(1-11a)
By simplifying:
- Adding like terms and multiplying constants into the bracket
- Negative sign will change the signs in the brackets
4a + 22 = -18 - 108a- 10 +110a
4a + 22 = -28 + 2a
- Taking terms with "a" to left side and others to right
- Signs of transferred terms will be changed
4a - 2a = -28 - 22
- Both terms on right side have negative sign so they wil be added and answer will have negative sign.
2a = -50
- Dividing both sides by 2 we get
a = -50/2
- Reducing to lowest term (dividing both by 2)
a = -25/
I hope it will help you!

Have a great day !
Price per pizza = total cost / # of pizzas
Price per pizza = $180 / 9 pizzas
Price per pizza = $20 per pizza
Price of any number of pizzas = Price per pizza * # of pizzas
Price of 15 pizzas = $20 * 15
Price of 15 pizzas = $300
Hope this helps! :)
