Answer:
7x-18
Step-by-step explanation:
3(2x-6)+x
multiply 3*2 to get 6x
then 3 *-6 = -18
then you have an extra x which you simply add to the 6x to get 7x

Answer:
30 feet
Step-by-step explanation:
To find the distance use a trigonometric ratio. Since we are looking for the hypotenuse and we are given the opposite side we will be using the ration of sine. We can set up the equation like this by using x as the measure we are looking for.
Sin of x=Opposite leg/Hypotnuse
Sin of 30= 15/x
Multiply by x and then divide by Sin of 30 to isolate the x.
x=15/Sin of 30
Plug it in to a calculator.
x=30

What is the solution of the following system of equations 5x+7y=3, 2x=-3y+1
Answer:
point form: (2,-1)
equation form: x=2,y=-1
Step-by-step explanation:
Answer:
X = 2 and y = -1
Step-by-step explanation:
add 3y to both sides of 2x = -3y + 1
2x + 3y = 1
5x + 7y = 3
multiply (2x + 3y = 1) by -5 and (5x + 7y =3) by 2
-10x - 15y = -5
10x + 14y = 6
-y = 1
y = -1
plug in y
2x = -3(-1) + 1
2x = 4
divide by 2
x = 2

three consecutive odd integers are such that the square of the third integer is 65 less than the sum of the squares of the first two. one solution is -7, -5, and -3. find three other consecutive odd integers that also satisfy the given conditions
We need to know about quadratic equation to solve this problem. The other three consecutive odd integers that satisfy the conditions are 11, 13 and 15.
We need to consider three consecutive odd integers, odd integers are integers that are not divisible by 2. Odd and even integers occur alternately so the the difference between two consecutive odd integers is always 2. We will consider one odd integer x, the next odd iinteger will be x+2 and the third odd integer will be x+4. Therefore we have our three consecutive odd integers, x, x+2 and x+4. It is said that the square of the third integer is 65 less than the sum of the squares of the first two. We can write this relation as
[tex](x+4)^{2} +65=x^{2} +(x+2)^{2}[/tex]
We can solve this equation to get a quadratic equation, and then solve it for x
[tex]x^{2} +8x+16+65=x^{2} +x^{2} +4x+4\\x^{2} +4x-8x+4-16-65=0\\x^{2} -4x-77=0[/tex]
We will solve the above quadratic equation for x
[tex]x^{2} -4x-77=0\\x^{2} +7x-11x-77=0\\x(x+7)-11(x+7)=0\\(x+7)(x-11)=0\\[/tex]
Therefore we get two values for x -7 and 11, from the question we already know about -7, we will find the three odd integers from 11 now
So the other three consecutive odd integers that satisfy the given conditions are 11,13 and 15.

Answer:
Step-by-step explanation:
5x - 9 = -24 + 10x
O One solution: -33
O One Solution: 3
O No Solution
O Infinite Solutions
Answer:
One Solution: 3
Step-by-step explanation:
5x - 9 = -24 + 10x
Subtract 5x from both sides. -9 = -24 + 5x
Add 24 to both sides. 15 = 5x

How is multiplying and dividing rational numbers similar to multiplying and dividing integers?
7 - (3 + 5) + (- 3 + 6) / 3 x 5
Answer:
4
Step-by-step explanation:
Always remember the order of operations: PEMDAS.
7 - (3 + 5) + (-3 + 6)/3 x 5
7 - (8) + (3)/3 x 5 (solve the parantheses first)
7 - 8 + 1 x 5 (3/3 comes first since multiplication and division have the same order; you would go left to right)
7 - 8 + 5 (Multiplication has a higher order than addition and subtraction)
4
Answer:
4
Step-by-step explanation:
Use PEMDAS
7 - (3+5) + (-3 + 6) / 3*5 (solve Parenthesis first)
7 - 8 + 3 / 3 * 5 (solve the division next)
7 - 8 + 1 * 5 (solve the multiplication next)
7 - 8 + 5 (subtract next)
-1 + 5 (lastly add)

Vinnie is 18 years old.What type of number is Vinnie's age? Is it Rational or
Irrational?
Answer: it is irrational
Step-by-step explanation:
Rational numbers are the numbers that can be expressed in the form of a ratio (i.e., P/Q and Q≠0) and irrational numbers cannot be expressed as a fraction. But both the numbers are real numbers and can be represented in a number line.
1/2 ( 2p + 9 ) = p + 5 solve equation
The given equation 1/2 ( 2p + 9 ) = p + 5 has no solution.
What is meant by linear equation has no solution?Whenever the two lines are parallel, a system of 2 linear equations in two variables has no solution.
In terms of algebra, this means that when we solve the system, we get such a false equation. On a graph, the lines never intersect because they share the identical slope but distinct y-intercepts.If the equations are inconsistent, a system of linear equations cannot have a solution. This means that no point can fulfill all of the equations simultaneously.As for the given question;
The expression is given as;
1/2 ( 2p + 9 ) = p + 5
Simplifying the equation;
(1/2)×2p + (1/2)×9 = p + 5
p + 9/2 = p + 5
As, the variable 'p is getting cancelled on the both side.
The expression given no solution.
Therefore, the stated linear equation in one variable 1/2 ( 2p + 9 ) = p + 5 does not posses any solution.

if vectors A&B are non zero vectors ,is it possible for their dot product and cross product to be zero? explain.
Answer:
It can be proved that it’s impossible.
The dot product is defined as:
a⋅b=∥a∥∥b∥cos(θ)
where θ is the angle between a and b .
The cross product is defined as:
a×b=∥a∥∥b∥sin(θ)n^
and the magnitude of this is given by:
∥a×b∥=∥a∥∥b∥sin(θ)
We also know that:
cos2(θ)+sin2(θ)=1
We can substitute the dot product and the magnitude of the cross product in here, to find:
(a⋅b)2+∥a×b∥2=∥a∥2∥b∥2
We’ve specified that a and b are non-zero vectors, so the right hand side cannot be zero. As a result, at least one of (a⋅b)2 or ∥a×b∥2 must be non-zero.

A pool company is creating an image for a dient that has the look of a 3-D image for a family pool and a similar dop pool. Find the value of x in the drawing below:
Answer:
x = 8
Step-by-step explanation:
Since both pools are similar, it follows that their side lengths are proportional.
Therefore:
[tex] \frac{BC}{FG} = \frac{AD}{EH} [/tex]
BC = 4
FG = 3
AD = x
EH = 6
Plug in the values
[tex] \frac{4}{3} = \frac{x}{6} [/tex]
Multiply both sides by 6
[tex] \frac{4}{3}*6 = \frac{x}{6}*6 [/tex]
[tex] \frac{24}{3} = x [/tex]
8 = x

In statistical inference for categorical data:___________.
a. Normal data is always a condition for inference.
b. Normal data is never one of the inference assumptions.
c. Normal data or large enough total sample size is one of the inference assumptions.
Answer:
b. Normal data is never one of the inference assumptions.
Step-by-step explanation:
A categorical data specifies among two or more groups, which one each observation belongs to, and one or more explanatory variables that can be used to predict this membership.
So, there are two propositions in statistical inference for categorical data
1. That each data in a cell is independent of the others.
2. That samples are randomly drawn.
Thus, there is no room for normality.

Identify the underlined place in 131.572. Then round the number to that place
The 5 is underlined
Can someone please help??
Answer:
The 5 is in the tenths place.
Step-by-step explanation:
:)
Answer:
131.6
Step-by-step explanation:
Since the 5 in 131.572 is underlined, we need to round the number to the nearest tenth. When rounding numbers, we need to look at the digit next to the rounded digit. The digit after 5 is 7.
If the digit after that is 1-4, we round down the 5. If the digit after that is 5-9, we round up the 5. Since 7 is between 5 and 9, we round the digit 5 to 6.
Thus, the rounded number would be: 131.6
