Answer:
Both drop-down answers are 0
Step-by-step explanation:
You are just replacing the x with a 0.
ALSO: The question at the top: Yes 2x + 6x is equivalent to 9x in this equation, because multiplying anything times 0 equals 0, so it doesn't matter what number comes before the x, it will always equal 0.
So when x = 0: 2x + 6x = 0, and 9x = 0, they are equivelant.
Answer:
There are 25 males and 21 females in the class
Step-by-step explanation:
Let us use the equation to solve the question
∵ A Spanish class has a total of 46 students
∵ The number of males is 4 more than the number of females
→ Assume that the number of females is x
∵ The number of females = x
∴ The number of males = x + 4
→ Add the numbers of males and females and equate the sum by 46
∴ x + x + 4 = 46
→ Add the like terms in the left side
∴ 2x + 4 = 46
→ Subtract 4 from both sides
∴ 2x + 4 - 4 = 46 - 4
∴ 2x = 42
→ Divide both sides by 2
∴ ![\frac{2x}{2}=\frac{42}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B2%7D%3D%5Cfrac%7B42%7D%7B2%7D)
∴ x = 21
∵ x represents the number of females
∴ There are 21 females
∵ x + 4 represents the number of males
∴ The number of males = 21 + 4 = 25
∴ There are 25 males
