Answer the following questions correctly i will know if this is wrong. i will report any incorrect answers! criteria for getting brainliest and not getting reported: - and make sure not to post random answers points are taken away when you are reported so don't think about answering it if you want only just want points to move up. - provide work or explanation if you can't provide work. you don't have to do both if you did already. 1. regina is 5 years older than her dog, and the sum of their ages is 19 years. if a represents regina’s age, in years, then the equation (a - 5) + a = 19 can be used to solve for the ages. use the equation to determine how old regina is.

Simplify the equation:

(a + -5) + a = 19

Reorder the terms:

(-5 + a) + a = 19

Remove the parenthesis around (-5 + a) :

-5 + a + a = 19

Combine like terms:

a + a = 2a

-5 + 2a = 19

Final equation:

-5 + 2a = 19

To solve for variable A:

You have to move all terms containing A to the left, all the other terms to the right.

Add '5' to each side of the equation.

-5 + 5 + 2a = 19 + 5

Combine like terms again:

-5 + 5 = 0

0 + 2a = 19 + 5

2a = 19 + 5

Combine like terms:

19 + 5 = 24

2a = 24

Finally divide each side by '2':

a = 12

Simplify:

a = 12

A=12

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
