Answer:
pastel de manzana: 32
pastel de calabaza: 48
Step-by-step explanation:
pastel de manzana: x
pastel de calabaza: 80 -x
7 x + 6 (80 - x) = 512
7x + 480 - 6x = 512
pastel de manzana: x = 512 - 480 = 32
pastel de calabaza: 80 - 32 = 48
cheque: 7 x 32 + 6 x 48 = 512

Answer:294
Step-by-step explanation: you’re trying to find the surface area of the cube to find out how much material Daria needs. To do so find the area of 1 face of the cube (which is a square). The problem gives us 1 side of the square as 7cm. A square has the same length for its 4 sides, so to find the area of that 1 face do 7 x 7=49. The question also gives the hint that a cube has 6 faces so you would multiply the 49 by 6 to get the total surface area of the cube. 49 x 6=294.
Not sure if this is right but hope it helps.
