Answer:
Translated according to the rule (x, y) =>(x+8, y+ 2) and reflected across the x- axis
Mom is 30 years old when Serena is 10 because 10 x 3 = 30.
They are 20 years apart. [This is key]
Half (.5) of mom's age will be = to Serena's age.
Therefore, when mom is 40 years old, Serena is 20 years old.
We can see that half of 40 = 20.
Hope this makes sense!
Answer:
$4.88
Step-by-step explanation:
Jessica made $16 mowing a neighbors yard
She brought a craft kit for $7.37
16-7.37

She used $3.75 to buy food for a food drive
8.63-3.75
= 4.88
Hence the amount Jessica put in the savings account is $4.88
