Answer:
b. fundamental arithmetic
Step-by-step explanation:
While fundamental arithmetic is required when solving linear equations, the use of it is not a named <em>method of solution</em>.
"Substitution", "Elimination", and "Graphing" are named methods of solving linear equations. Sometimes the line can be blurred between substitution and elimination, but these methods generally involve distinct sets of steps (which include the use of fundamental arithmetic).

Answer:
128cm²
Step-by-step explanation:
<em>To find out how much material he needs, you need to find the surface area of the box. Each box has 6 sides, 2 of 3 different sides. </em>
Surface area = 2(6 × 4) + 2(6 × 4) + 2(4 × 4)
= 128cm²
I think it’s 25/6 (not sure)
Answer: 6 cajas de cada tipo de fruta.
Step-by-step explanation:
En cada caja de manzanas, tenemos 13 manzanas.
En cada caja de limones, tenemos 17 limones.
Si el numero total de cajas es C, entonces el numero total de manzanas es:
C*13
y el numero total de limones es: C*17.
Si en total tenemos 180 frutas, entonces tenemos que:
C*13 + C*17 = 180
C*(13 + 17) = 180
C*30 = 180
C = 180/30 = 6
Tenemos 6 cajas de cada tipo de fruta.
