First, let x or any variable represent the number of paintings Kate initially has. After selling 12 of it, her paintings now becomes only x - 12. Then, she purchased 7 more making the number of her paintings become x - 12 + 7 = x - 5. This number tantamount to 21.
x - 5 = 21 ; x = 26
Thus, Kate initially had 26 paintings.
Answer:
13
Step-by-step explanation:
Create an equation: g+(G+4)(2)=35
Parentheses: g+2(G+4)=35
Distributive property: g+2g+8=35
Combine like terms: 3g+8=35
Subtractive property: 3g=27
Division property: g=9
Greg is 9. Since Ava is 4 years older you add 4 to find her age. Ava is 13. You take Ava’s age times 2 ( equals 26) then add Greg’s age (equals 35). And it should equal 35.
