Hi! i am new and i need i need to show work and this is for a grade

1) 1.79×5.3=9.487
1.79 is one liter so 5.3 gallons is 9.487

2) 0.75 cups of blueberries for 1 batch
You need 5 batches
so
multiply 0.75 by 5
0.75×5=3.75
you already have 2.5 cups of blueberries
So you need to find out how much you need to buy
subtract 2.5 from 3.75
3.75-2.5=1.15

The center point are vertical angles:

180 - 88 -38 = 54

X = 180 - 54 - 63= 63

The answer is c. 63
