My aunt's age is 43.
My brother's age is 16.
My mother's age is 41.
<h3>What are the current ages?</h3>
In order to determine the current ages, the year the ages are been calculated has to be determined first. The year can be determined by adding my Tali's age to the year he was born.
2008 + 13 = 2021
What is my aunt's age = 2021 - 1978 = 43
What is my brother's age = 2021 - 2005 = 16
What is my mother's age = 2021 - 1980 = 41

Answer:
x=-4 and y=10
Step-by-step explanation:
Use the second equation to make y=x+6
sub y=x+6 into the first equation
-x-2*(x+6)=0
-x-2x-12=0
-3x-12=0
3x=-12
x=-4
Now sub x=-4 into the second equation
-(-4)+y=6
y=6+4
y=10
567 / 18 = 31.5
But because she can't make half a shelf, the answer would be 32 shelves
D∩E=D This is because since D is a subset of E then the elements they will have in common are the elements in D and D is not a null set
Step-by-step explanation:
step 1. (13x + 8) + (2x + 7) = 180 (definition of same side interior angles)
step 2. 15x + 15 = 180 (like terms)
step 3. 15x = 165 (subtract 15 from each side)
step 4. x = 11. (divide both sides by 15)
