What is 18/12 as a mixed number in simplest form
Answer: 1 1/2
You can write this as 1 & 1/2
The whole part is 1. The fractional part is 1/2
==========================================================
Explanation:
Let's say we had 18 cookies to hand out to 12 students.
How many cookies does each student get?
Using a calculator shows that 18/12 = 1.5 which means they get one whole cookie each
The leftovers is 18-12 = 6
Then notice how 6/12 = 1/2
So that's how the improper fraction 18/12 becomes the mixed number 1 & 1/2
So each student gets 1 full cookie, plus half a cookie.
------------------
Or we could do the problem like this
18/12 = (12+6)/12
18/12 = (12/12)+(6/12)
18/12 = 1 + (1/2)
18/12 = 1 & 1/2

P, Q, V, and K are collinear with V between K and P, and Q between V and K. If VP = 14x + 4, PK = x + 630, VQ = 17x + 6, and KQ = 11x + 5, solve for VP.
If the points P, Q, V and K are collinear, they will follow the segment addition postulate.
Measure of segment VP will be 214 units.
It's given in the question,
P, Q, V and K are collinear.VP = 14x + 4PK = x + 630VQ = 17x + 6KQ = 11x + 5By segment addition postulate,
KQ + VQ + VP = KP
Substitute the values in the expression,
(11x + 5) + (17x + 6) + (14x + 4) = x + 630
(11x + 17x + 14x) + (5 + 6 + 4) = x + 630
42x + 15 = x + 630
42x - x = 630 - 15
41x = 615
x = [tex]\frac{615}{41}[/tex]
x = 15
Therefore, measure of VP = (14x + 4)
= 14(15) + 4
= 214 units
Measure of segment VP will be 214 units.

Zach and Ginny are building model cars. Ginny's car is 2 more than 3 times the length of Zach's car. The sum of the lengths of both cars is 30 inches. Write an equation to determine the lengths of Zach's and Ginny's cars.
3x + 2 = 30
x + 2 + 3x = 30
2x + 3 = 30
x + 2x + 3 = 30
Answer:
x + 2 + 3x = 30
Step-by-step explanation:
Both lengths are unknown, but Ginny's car length is described in terms of Zach's car length, so we choose a variable for Zach's car length.
Let x = Zach's car length.
Zach's car length is x.
"Ginny's car is 2 more than 3 times the length of Zach's car."
Ginny's car length is 2 + 3x.
Add the lengths:
x + 2 + 3x
"The sum of the lengths of both cars is 30 inches."
x + 2 + 3x = 30
Answer: x + 2 + 3x = 30

Step-by-step explanation:
[tex]3 - \frac{x}{5} = 8[/tex]
[tex]5(3 - \frac{x}{5} ) = 5 \times 8[/tex]
[tex]5 \times 3 - 5 \times \frac{x}{5} = 5 \times 8[/tex]
[tex]15 - 5 \times \frac{x}{5} = 40[/tex]
[tex]15 - x = 40[/tex]
[tex] - x = 40 - 15[/tex]
[tex] - x = 25[/tex]
[tex]x = - 25[/tex]
Answer:
x = - 25
Step-by-step explanation:
Given
3 - [tex]\frac{x}{5}[/tex] = 8 ( subtract 3 from both sides )
- [tex]\frac{x}{5}[/tex] = 5 ( multiply both sides by 5 to clear the fraction )
- x = 25 ( multiply both sides by - 1 )
x = - 25

You withdraw $40 each month from your savings account. what integer represents the change in your balance after 4 months?
Answer:
The balance would be $160 from whatever it was before the 4 months.
Step-by-step explanation:
Since the bank balance is being added by 40 for each month for 4 months, 4 * 40 is just 4*4 with an extra zero on the end. so that would be $160.
So if the balance before was $40, then the new balance after 4 months would be $200.
If there's no money previously, then there is now $160 after 4 months.
If there's a value before the $40 for 4 months, let me know and I will explain and tell you what it is.

Sin A = x Cos A

7a) 1 - Sin A = 1/2
[tex]1 = \dfrac{1}{2}+ Sin \ A\\\\1-\dfrac{1}{2}=Sin \ A\\\\\dfrac{1}{2}=Sin \ A\\[/tex]
⇒ A = 30°
Sec² A = Sec² 30° = [tex](\frac{2}{\sqrt{3}})^{2}=\frac{2^{2}}{(\sqrt{3)^{2}}}=\frac{4}{3}[/tex]
[tex]tan^{2} \ A = tan^{2} 30 = (\dfrac{1}{\sqrt{3}})^{2} = \dfrac{1}{3}[/tex]
LHS = 6 Sec² A + 9 tan² A

The square of the difference between 2x and y
Answer:
this question doesn`t have much information but here`s my best guess
(2x-y)^2
[tex](2x - y)^2[/tex]. This expression represents the result of squaring the difference between 2x and y.
1. **Difference between 2x and y:** The difference between 2x and y is calculated by subtracting y from 2x. This gives us the expression "2x - y," which represents the numerical difference between these two quantities.
2. **Square of the Difference:** To square this difference, we simply multiply "2x - y" by itself. When you square something, you multiply it by itself. In mathematical notation, squaring is denoted using an exponent of 2, which is written as "^2."
So, combining the two steps, we have:
[tex](2x - y)^2[/tex]. This expression represents the result of squaring the difference between 2x and y. When you expand this expression, you get a quadratic expression, which may include terms like [tex]4x^2, y^2[/tex], and -2xy, among others, depending on the values of x and y.

Write the equation of the line perpendicular to 2x-5y=-12 that passes through the point (10,-1) in slope-intercept form.
Answer:
[tex]y=-\frac{5}{2}x-24[/tex]
Step-by-step explanation:
[tex]2x-5y=-12\\5y=2x+12\\y=\frac{2}{5}x+\frac{12}{5}\\[/tex]
if two lines perpendicular,
[tex]m_{1} .m_{2}=-1\\ \frac{2}{5} .m_{2}=-1\\m_{2}=-\frac{5}{2}[/tex]
the line perpendicular to this line is
[tex]y=-\frac{5}{2}x+k[/tex] ; k ∈ R
the line passes through the point (10,-1)
so,
[tex]-1=-\frac{5}{2} (10)+k\\-1=-25+k\\k=-24[/tex]
∴the equation of the line perpendicular to 2x-5y=-12 that passes through the point (10,-1) is

so, x = 2 is applicable.
Point B is the midpoint of AC. AB=3x and AC=5x+21 . What is the value of AB?
First, let's write down what we know.
AB = 3x
AC = 5x+21
Since B is the midpoint, AB is half the length of AC. The sum of AB + AB is equal to the length of AC.
AB + AB = AC
Let's plug in our values.
3x + 3x = 5x + 21
Simplify the left side.
6x = 5x + 21
Subtract 5x from both sides.
x = 21
Now, let's plug in 21 for x in AB
AB = 3x = 3(21) = 63

Answer:
64w^2
Step-by-step explanation:
Because 8w is in parentheses, you must apply the exponent to both the 8 and w.
So, it becomes (8*8)(x*x) which equals (64)(x^2).
Which then gives you your final answer, 64x^2.
