7/4 = (4 + 3)/4 = 4/4 + 3/4 = 1 + 3/4 =
1 3/4
Let
x = loaves of bread
y = batches of muffins
You must make a system of two equations with two unknowns that describe the problem
3.5x + 2.5y = 17 --- (1)
0.75x + 0.75y = 4.5 --- (2)
Resolving we have
x = 6-y (from (2))
replacing in (1)
3.5 (6-y) + 2.5y = 17
21 - 3.5y + 2.5y = 17
y = 21-17 = 4
Then substituting in (2)
x = 6-y = 6-4 = 2
Answer
Helena could bake:
2 loaves of bread
4 batches of muffins
Answer:
d
Step-by-step explanation:
d is not true because width and thickness doesn't matter
El área de un cuadrado es igual a 8 veces la medida de su lado. ¿Cuánto mide por lado el cuadrado ?
El Area de un Cuadrado es : A = L²
L² = 8 x L -------------> L² / L = 8 ----------> L = 8
Cada lado mide 8 unidades.
2) El triple del área de un cuadrado menos seis veces la medida de su lado es igual a cero ¿Cuánto mide por lado el cuadrado?
El Area de un Cuadrado es : A = L²
(3 x L²) - 6 L = 0
Factorizando : 3L ( L - 2 ) = 0 --------> L = 0 ; L = 2
Cada lado mide 2 unidades.
