Help Simplify 6(x + 4).
Answers
Answer:
6x+24
Step-by-step explanation:
The simplified form of the expression 6(x + 4) is 6x + 24.
We have,
To simplify the expression 6(x + 4), we can apply the distributive property of multiplication over addition.
The distributive property states that when we have a number multiplied by a sum of terms, we can distribute the multiplication to each term separately and then simplify.
In this case, we have 6 multiplied by the sum (x + 4). Applying the distributive property, we can multiply 6 by both x and 4:
6(x + 4) = 6 * x + 6 * 4
Simplifying further:
6x + 24
Therefore,
The simplified form of the expression 6(x + 4) is 6x + 24.

1.The growth of a sample of bacteria can be modeled by the function b(t)=100(1.06)t where b is the number of bacteria and t is time in hours.
What is the number of total bacteria after 3 hours?
Answers
Given:
The growth of a sample of bacteria can be modeled by the function
[tex]b(t)=100(1.06)^t[/tex]
where, b is the number of bacteria and t is time in hours.
To find:
The number of total bacteria after 3 hours.
Solution:
We have,
[tex]b(t)=100(1.06)^t[/tex]
Here, b(t) number of total bacteria after t hours.
Substitute t=3 in the given function, to find the number of total bacteria after 3 hours.
[tex]b(t)=100(1.06)^3[/tex]
[tex]b(t)=100(1.191016)[/tex]
[tex]b(t)=119.1016 [/tex]
Therefore, the number of total bacteria after 3 hours is 119.1016.

Karen bought cupcakes for her sister's birthday party. 3 cupcakes had sprinkles on top. The other 27 cupcakes did not have sprinkles. What percentage of the cupcakes had sprinkles?
Answers
Answer:
10%
Step-by-step explanation:
so
3 cupcakes had sprinkles
27 didn't have sprinkles
which means that there are a total of 30 cupcakes, (because 3 + 27 is 30)
so then set up a proportion
part/whole = percent/one hundred
substitute in the given values
3 / 30= precent/100
simplify
1/10 = precent/100
you don't have to use cross products here because it is pretty obvious that 10 * 10 = 100 so then just multiply 1/10 by 10 and you get your answer
percent = 10

A. 23/24
B. 1 1/4
C. 3 1/4
D. 3 11/24
Answers
Answer:
[tex]3\frac{11}{24}[/tex]
Step-by-step explanation:
Given parameters:
Leftover pizza from the Science club = [tex]1\frac{1}{4}[/tex]
Left over pizza from french club = [tex]2\frac{5}{24}[/tex]
Unknown;
Total left over pizzas between the two clubs = ?
Now to solve problem, simply add the leftover from the science club and the french club together;
Total left over pizza = [tex]1\frac{1}{4}[/tex] + [tex]2\frac{5}{24}[/tex]
= [tex]\frac{5}{4} + \frac{53}{24}[/tex]
= [tex]\frac{83}{24}[/tex]
= [tex]3\frac{11}{24}[/tex]
The total left over pizza between the two clubs is [tex]3\frac{11}{24}[/tex]

Parallel to y=-3x+4, x-intercept at 4
Answers
Answer:
y = -3x + 12
Step-by-step explanation:
The slope of parallel line is the same as the original line.
If the x-intercept is 4, this as a point can be stated as (4, 0)
We can now solve for the y-intercept.
y = -3x + b
0 = -3(4) + b
0 = -12 + b
12 = b
Put everything we solved for back into the formula [ y = mx + b ]
y = -3x + 12
