Answer:
h+6/5=3
We move all terms to the left:
h+6/5-(3)=0
determiningTheFunctionDomain
h-3+6/5=0
We multiply all the terms by the denominator
h*5+6-3*5=0
We add all the numbers together, and all the variables
h*5-9=0
Wy multiply elements
5h-9=0
We move all terms containing h to the left, all other terms to the right
5h=9
h=9/5
h=1+4/5

What is 10a - 5b if a = 25 and b = 3
Answer:
[tex]\boxed{235}[/tex]
Step-by-step explanation:
Hey there!
Well given that,
a = 25
b = 3
10(25) - 5(3)
250 - 15
= 235
Hope this helps :)
Hi there! Hopefully this helps!
-------------------------------------------------------------------------------------------------------
Answer: 235.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~First we need to substitute the value of the variable into the expression:
10a - 5b = 10(25) - 5(3).
Now we Multiply 10 and 25 to get 250.
250 − 5 × 3 = 235
Multiply 5 and 3 to get 15.
250 − 15 = 235
Subtract 15 from 250 to get, you guessed it, 235!Who knows the answer!?

Answer:
x = 95
Step-by-step explanation:
The sum of the angles of a quadrilateral is 360
x +115+46+ 104 = 360
Combine like terms
x+265=360
Subtract 265 from each side
x +265-265 = 360-265
x = 95

Question is below PLEASE HURRY I'M DESPERATE
Answer:
a) 15.5 cm
b) 37.2 cm
Step-by-step explanation:
For part a you would write 4(x+1) because perimeter is adding the sides and all sides of a square are equal. then you would set that equal to 66 and get 4(x+1)=66 and then distribute the 4 and get 4x+4=66 and then subtract the 4 from 66 and get 4x=62. Then you divide 62 by 4 and get 15.5.
For part b you do essentially the same thing but set it equal to 152.8 and get 4(x+1)=152.8 and then distribute the 4 to get 4x+4=152.8 then subtract the 4 and get 148.8 and then divide that by 4 and get 37.2.
Answer:
Step-by-step explanation:
a) Length = (x +1) cm
Perimeter of square = 66 cm
4 * length = 66
4* (x +1) = 66
Divide both sides by 4
[tex]\frac{4*(x +1)}{4}=\frac{66}{4}[/tex]
x + 1 = 16.5
Subtract 1 from both sides,
x = 16.5 -1
x = 15.5 cm
b) Length = (x +1) cm
Perimeter of square = 152.8 cm
4 * length = 152.8
4* (x +1) = 152.8
Divide both sides by 4
[tex]\frac{4*(x +1)}{4}=\frac{152.8}{4}[/tex]
x + 1 = 38.2
Subtract 1 from both sides,
x = 38.2 -1
x = 37.2 cm
Use the figure to the right to find the value of PT. T is the midpoint of PQ.
PT = 5x +2 and TQ = 7x-6
PT=
(Simplify your answer.)
Answer:
22
Step-by-step explanation:
Given that T is the midpoint of line PQ, PT and TQ are both equal segments of line PQ.
PT is given as 5x + 2,
TQ = 7x - 6
Therefore:
[tex] 5x + 2 = 7x - 6 [/tex]
Solve for x
[tex] 5x + 2 - 7x = 7x - 6 - 7x [/tex]
[tex] -2x + 2 = -6 [/tex]
[tex] -2x + 2 - 2 = -6 - 2 [/tex]
[tex] -2x = -8 [/tex]
[tex] \frac{-2x}{-2} = \frac{-8}{-2} [/tex]
[tex] x = 4 [/tex]
PT = [tex] 5x + 2 [/tex]
Input the value of x
[tex] PT = 5(4) + 2 = 20 + 2 = 22 [/tex]

Math SAT scores are Normally distributed with mean µ=500 and standard deviation σ=100 . The curve is displayed above. What percentage of the SAT Math scores are less than one standard deviation above the mean?
Answer:
Step-by-step explanation:
mean µ = 500
standard deviation σ = 100
Required P ( X < µ + σ )
= P ( X < 500 + 100 )
= P ( X < 600 )
= P [Z < (X - µ) / σ ]
= P [Z < (600 - 500) / 100 ]
= P [Z < + 1 ]
= .8413
In terms of percent the probability is 84.13 % .

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The greatest common factor of 18 and 35.
Now,
See all the factors of 18.
= 1, 2, 3, 6, 9, and 18.
See all the factors of 35.
= 1, 5, 7, and 35.
We see that,
The greatest common factor is 1.
Thus,
The greatest common factor of 18 and 35 is 1.

For a parade, attendance was rounded as 10,000 to the nearest hundred. What was the
greatest and least number of people that could have attended the parade? Explain your
answer.
Answer:
The least is 9950 and the largest is 10049 people
Step-by-step explanation:
If the number is rounded to the nearest hundred, the smallest number of people that could have attended the parade is 9950 because, rounding up the number 9950 to the nearest hundred would give 10000. If the number 9950 is decreased by 1 (9949), and rounded up to nearest hundred you won't get 10000. Hence the smallest number of people is 9950
While the largest number of people is 10049. 10049 to the nearest hundred is 10000. A further increase to the number 10049 would give a number greater than 10000 when rounded to nearest hundred.
What is the missing value in x2y8 · x3y? = x5y5?
Answer:
-3
Step-by-step explanation:
To find:
The value of '?' in the following expression:
[tex]x^2y^8.x^3y^? = x^5y^5[/tex]
Solution:
First of all, let us have a look at a few rules of the exponents:
[tex]1.\ a^b.a^c=a^{b+c}[/tex]
[tex]2.\ a^b.a^{-c}=a^{b-c}[/tex]
Let us apply these rules and try to find out the missing value ('?') in the given expression.
Left Hand Side (LHS):
[tex]x^2y^8.x^3y^?\\\Rightarrow x^2.x^3.y^8.y^?\\\Rightarrow x^{2+3}y^{8+?}\\\Rightarrow x^{5}y^{8+?}[/tex]
Now, let us compare the LHS with RHS, we get:
[tex]x^{5}y^{8+?} = x^{5}y^{5}[/tex]
Dividing with [tex]x^5[/tex] on both sides:
[tex]y^{8+?} = y^5\\\Rightarrow 8+? = 5\\\Rightarrow ? = 5-8 \\\Rightarrow ? =-3[/tex]
Therefore, the missing value in the expression is -3.
Answer:
-3
Rules of the exponents power:
1. a^b * a^c = a^(b+c)
2. a^b * a^(-c) = a^(b-c)
Applying these rules on Left Hand Side of the expression given:
= x2y8 * x3y?
= x2x3 * y8y?
= x^(2 + 3) * y^(8 + ?)
Right hand side of the expression given:
= x5y5
Comparing the LHS and RHS, we get
x5y^(8 + ?) = x5y5
Dividing with x5 on both sides:
y^(8 + ?) = y5
8 + ? = 5
? = 5 - 8
? = -3
Therefore, the missing value in the expression is -3.

If a dog moves 3 meters due East and then 4 meters due North, what will be the dispalcement of the dog?
Answer:
The displacement of the dog which is the shortest distance between the two points is 5 meters 53.13° North of East
Step-by-step explanation:
The given parameters are;
The dog's displacement due East = 3 meters
The dog's displacement due North = 4 meters
The displacement, D motion of the dog can be written in vector form as follows;
D = 3i + 4j
The magnitude of the displacement is given as follows;
[tex]\left | D\right | = \sqrt{(3 \ meters)^2 + (4 \ meters)^2} = \sqrt{25 \ meters^2} =5 \ meters[/tex]
The displacement is the shortest distance between two points
The direction is given tan⁻¹(4/3) = 53.13° North of East
The displacement of the dog which is the shortest distance between the two points = 5 meters 53.13° North of East.
