Mr. Williamson bought 4 boxes of chewy granola bars and 5 boxes of crunchy granola bars. Each box contained the same number of granola bars. He took all 72 granola bars to the class picnic. How many granola bars were in each box?
Let x represent the number of granola bars in each box.
Step 1: Write an equation.
Step 2: Identify and combine like terms.
Step 3: Use the properties of equality and inverse operations to solve the equation.
Answers
Answer: There were 8 granola bars in each box, x = 8.
Step-by-step explanation:
The first step is write an equation:
4x + 5x = 72
The second step is to combine like terms:
4x + 5x = 72
9x = 72
Step 3 is to use the properties of equality and inverse operations to solve the equation:
9x/9 = 72/9
x = 8
Since x = 8, there were 8 granola bars in each box.

Which function is (x-1) a real root?
Answers
Answer:
D
Step-by-step explanation:
According to the Factor Theorem:
In order for a factor in the form of [tex](x-a)[/tex] to be a root for a function [tex]f(x)[/tex], [tex]f(a)[/tex] must be 0.
Our factor is [tex](x-1)[/tex].
Therefore, [tex]a=1[/tex].
So, we will evaluate [tex]f(1)[/tex] for all the choices.
Doing so, we can see that, starting from the top, we have:
[tex]\begin{aligned}f_1(1)&=-12\\ f_2(1) &=8 \\ f_3(1)&=24 \\ f_4(1)&=0 \end{aligned}[/tex]
The choice that yields 0 as an answer is D.
So, the function for which [tex](x-1)[/tex] is a real root is choice D.

Camilla and Anne work as interior decorators in the city. Camilla can decorate a home in 5 days while Anne can
complete a home in 4 days. Working together, how long will it take them to decorate 2 homes?
Answers
Answer:
It will take them 4.44 days to decorate 2 homes.
Step-by-step explanation:
Given that:
Camilla can decorate a home in 5 days
Anne can complete a home in 4 days
Let,
x be the time taken by Camilla and Anne to decorate 1 home.
[tex]\frac{1}{Camilla's time}+\frac{1}{Anne's\ time} = \frac{1}{total\ time}\\[/tex]
[tex]\frac{1}{5}+\frac{1}{4}=\frac{1}{x}[/tex]
Taking LCM;
[tex]\frac{4+5}{20}=\frac{1}{x}\\\\\frac{9}{20}=\frac{1}{x}\\x=\frac{20}{9}[/tex]
Time taken by Camilla and Anne to decorate 2 homes = [tex]\frac{20}{9}*2=\frac{40}{9}[/tex]
Time taken to decorate Camilla and Anne 2 homes = 4.44 days
Hence,
It will take them 4.44 days to decorate 2 homes.

Andrew is x years old. Blake is 7 years younger than Andrew. in 5 years time Blake will be twice the age of Carla. how old Carla now in terms of x?
Answers
Answer: Carla is 1/2x years old
Step-by-step explanation:
The present age of Carla in terms of x is (x - 2) / x.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Andrew's age = x
Blake's age = x - 7
Carla's age = C
After 5 years,
Blake = (x - 7) + 5 = x - 7 + 5 = x - 2
Now,
x - 2 = 2C
C = (x - 2) / 2
Thus,
Carla's age is (x - 2) / 2.
