Answer:
Han bebido la misma cantidad.
Step-by-step explanation:
De la pregunta,
Frederico = 2/5 vaso de leche
María = 4/10 vaso de leche
Simplificando el gozo de la leche para María
= 2/5
Por tanto, podemos decir que:
Sí, han bebido la misma cantidad.
Answer:
She should have substituted y = 17 - 2x in the first equation
Step-by-step explanation:
3x + 4y = 33
2x + y = 17
y = 17 - 2x
3x + 4(17 - 2x) = 33
3x + 68 - 8x = 33
5x = 35
x = 7
y = 17 - 2(7)
y = 3
x = 7, y = 3
Only one solution
N + 1 = 4(n – 8)
Use distributive property for this part: 4(n – 8) ----> 4n - 32
n + 1 = 4n - 32
Get the variable on one side:
n + 1 = 4n - 32
-n -n
1= 3n - 32
Get the variable on its own:
1= 3n - 32
+32 +32
33 = 3n
Divide by 3 on both sides:
33/3 = 3n/3
n = 11
Note: In option A, it should be "+" instead of "(".
Given:
The expression is

To find:
The equivalent expression.
Solution:
We have,

Using distributive property, we get


On combining like terms, we get


The expression
is equivalent to the given expression.
Therefore, the correct option is A.
Answer: Commutative Property of Multiplication
<u>Step-by-step explanation:</u>
Commutative property is when two terms trade places.
(a · 3) × b = b × (a · 3)
Notice that (a · 3) switched places with b
