The age of the youngest child will be 11 years old.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
The oldest child in a family of four children is twice as old as the youngest.
Let x be the age of the youngest child and y be the age of the oldest child. Then the equation is given as,
y = 2x ...1
The two middle children are 12 and 16 years old. If the average age of the children is 15.25. Then the equation is given as,
(x + 12 + 16 + y) / 4 = 15.25
x + y = 33 ...2
From equations 1 and 2, then we have
x + 2x = 33
3x = 33
x = 11
The age of the youngest child will be 11 years old.
More about the solution of the equation link is given below.

EASY PEASY
n = -18
Step-by-step explanation:
Simplifying
n + 7 = -11
Reorder the term:
7 + n = -11
Solving
7 + n = -11
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + n = -11 + -7
Combine like terms: 7 + -7 = 0
0 + n = -11 + -7
n = -11 + -7
Combine like terms: -11 + -7 = -18
n = -18
Simplifying
n = -18

Maria recently hired a plumber to do some necessary work. On the final bill, Maria was charged a total of $473. The amount listed for parts was $335 and the rest of the bill was for labor. If the hourly rate for labor was $46, how many hours of labor was needed to complete the job?
(A) First write an equation you can use to answer this question. Use x as your variable. The equation is __________________
(B) Solve your equation in part (A) to find the number of labor hours needed to do the job. Answer: The number of labor hours was ________________________
Answer:
A)473 = 335 - 46x
B) 3
Step-by-step explanation:
A)
473 = 335 - 46x
x = the hours of labor needed.
B)
Solve for x
473 = 335 - 46x
subtract 335 from both sides
138 = 46x
divide both sides by 46
3 = x
Answer:
A) [tex]46x+335=473[/tex] B)[tex]x=3[/tex]
Step-by-step explanation:
473 is the total amount, which means it is the end result
335 represents a constant since it is a base price
the hourly rate is a variable, due to the fact that it depends on how many hours he spent working.
variable + constant = total price
[tex]46x+335=473[/tex]
Now to solve this, first subtract [tex]335[/tex] from both sides
[tex]46x=138[/tex]
Next divide both sides by [tex]46[/tex] to isolate the variable
[tex]x= \frac{138}{46}[/tex]
This can be simplified to: [tex]x=3[/tex]

Step-by-step explanation:
Answer:
1,000,000,000
Step-by-step explanation:
When multiplying numbers with only 0's just insert the amount of zeros from the lower number into the bigger number:
1000 = 3 zeros
1000000 = 6 zeros
3 zeros + 6 zeros = 9 zeros
So put 9 zeros in the answer:
