Step-by-step explanation:
a cube has 6 faces so 6.75 x 6 = 40.5
Answer:
The answer is b.
Step-by-step explanation:
Eduardo sold 1 white chocolate chip and 3 oatmeal.
15 + (18 x 3) = 69
Heidi sold 2 white chocolate chip and 1 oatmeal.
(15 x 2) + 18 = 48
2t + 5b = 20
8t + 3b = 29
Multiply the first equation by-4
-8t -20b = -80
8t + 3b = 29
-17b = -51
b = 3
Plug 3 in for b into either equation and solve for t.
2t + 5(3) = 20
2t + 15 = 20
2t = 5
Divide both sides by 2
t = 2.50
