12. Simplify -48c^2d^4/-8cd
Answer:
6cd^3
Step-by-step explanation:
-48c^2d^4/-8cd
you divide the -48 by -8 and you get 6.
6c^2d^4/cd
when you divide c^2 by c, d^4 by d you get c and d^3 - this is kind of because c^2 is cxc/d^4 is dxdxdxd and when you divide it by c/d the ^ decreases.

I'm 3 times younger than my mom but 3 times older than my younger brother. Mom is older than my younger brother by 40 years. how old am I?
Given:
I'm 3 times younger than my mom but 3 times older than my younger brother.
Mom is older than my younger brother by 40 years.
To find:
How old am I.
Solution:
Let x be the age of the younger brother.
I'm 3 times older than my younger brother. So, my age is 3x.
I'm 3 times younger than my mom. So, she is 3 times older than me and her are is 3(3x)=9x.
The difference between the age mother and younger brother is 40 years.
[tex]9x-x=40[/tex]
[tex]8x=40[/tex]
Divide both sides by 8.
[tex]x=\dfrac{40}{8}[/tex]
[tex]x=5[/tex]
Now,
My age [tex]=3x[/tex]
[tex]=3(5)[/tex]
[tex]=15[/tex]
Therefore, I'm 15 years old.

find the vertexform (x)=x2-12x+36
Answer:
Vertex form pf y = x^2 + 12x + 36.
Step-by-step explanation:
y = (x + 6)^2
x-coordinate of vertex:
(x + 6) = 0--> x = - 6
y-coordinate of vertex: y = y(-6) = 36 - 72 + 36 = 0
Vertex form: y = (x + 6)^2
Answer:
2
Step-by-step explanation:
X=x 2-12x+36
X+X+12x=38
14x=38
X=38/14
X=2

Answer:
938 feet
Step-by-step explanation:
The diagonal is the hypotenuse of a right triangle with side lengths 900 ft and 264 ft. The Pythagorean theorem tells you how to compute its length.
d² = 900² +264² = 879,696
d = √879,696 ≈ 937.92 . . . . feet
They would walk about 938 feet.
Kieran buys a car for $8000
The following year he sells the car for $7500
Find the percentage loss.
Answer:
6.25% I think
Step-by-step explanation:
If Kiara sells car at $7500 and it is of $8000 then she is having a loss of 6.25%.
What is percentage?A percentage is the number or ratio which is expressed as a fraction of 100.
How to calculate percentage?We have been given the buying value=$8000
Selling value=$7500
Loss=Buying value- selling value
=8000-7500
=$500
Percentage of loss=loss/ buying value*100
=500/8000*100
=6.25%
If we want to check our answer then we can multiply our percentage with the buying value.
=8000*6.25%
=500
Hence if Kiara sells car at $7500 and it is of $8000 then she is having a loss of 6.25%.

The admission fee at an amusement park is 1.5 dollars for children and 4 dollars for adults. On a certain
day 369 people entered the park, and the admission fees collected totaled 1016 dollars. How many
children and how many adults were admitted?
Answer:
184 children and 185 adults!
Step-by-step explanation:
So let's suppose there are x children who entered the park that day, then there will be (369-x) adults who entered the park that day.
So we have an equation!
1.5x+4(369-x)=1016
1.5x+1476-4x=1016
Then we swivel things around a bit.
1476-1016=4x-1.5x
2.5x=460
x=184
There are 184 children in that park that day! Wow, that's a lot of people, next we calculate the number of adults:
369-184
=185
OK, 184 children and 185 adults!

how do i do slope-intercepts
Answer:
To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.
