Find the solution for
h - 12 =6
Answer:
H-12=6
H−12+12=6+12
h=18
Answer:
h=18
Step-by-step explanation:
h-12=6
is the normal eqaution, you need to determine the value of h, on the left side of the eqaution you have negative twelve we must get the h on its own by moving the 12 to the right side using of basic math rules you must know that when you have a negative and want to move it to the right hand side it must become a positive
so in formula it wil look like this
h = 6 + 12
Add up 6 with 12 that wil give you 18
so the value of h is then 18
h = 18
When 3 is added to a number, and the result is multiplied by 5, you obtain two times the number
Hi
to solve you must transcrive every word in math terms correctly.
so let's first give a name to our mysterious number. As you know, in math we generally call unknown by letter. " X"
so let's now play the detective.
what do we know on " X" ?
we add 3 to X so we have : X+3
then we multiply by 5. so. ( X+3) *5 .
if we do that we have twice X , so 2X
so ( X+3) * 5 = 2 X
now that we have translatted our data in math term, let's unmask. " X"
( X+3) *5 = 2X
5*X +3*5 = 2X
5X +15 = 2X
5X-2X = -15
3X = -15
X = -15/3
X = -5
So is " -5" is our guy.
let's check it out to be sure .
-5 +3 = -2
-2*5 = -10
-10 is twice -5. so -5 is the correct answer.
Ps : some operation are commonly implied. if you do not. know how I could write some line in the calculus, dont hesitate to ask in comments.
There is no mysteries in math everything is done according to rules and can be explained. So don't hesitate !

When the sum of the internal angles of a polygon is 10 right angles, then how many sides does it have?
Answer:
7
Step-by-step explanation:
Let's say our sum is s.
s = 10 right angles
a right angle is 90 degrees
s = 10 (90)
s= 900
Given the amount of sides in a polygon (n), the sum of the interior angles is equal to
(n-2) * 180
Therefore, the sum of the interior angles is equal to
(n-2) * 180 = 900
divide both sides by 180 to help isolate n
n-2 = 5
add 2 to both sides to isolate n
n = 7

Find the slope that is PARALLEL and PERPENDICULAR to the equation of the line y = -1/2x+6.
Answer:
parallel: -1/2
perpendicular: 2
Step-by-step explanation:
lines that are parallel have the same slope because they never intersect
lines that perpendicular, have the opposite reciprocal slope.
y = mx + b
where m is the slope
y = -1/2x + 6
-1/2 is the slope.
the slope in the equation given: -1/2
the slope parallel to the line given : -1/2
the slope perpendicular : opposite reciprocal, so the opposite of -1/2 is 1/2 and the reciprocal of 1/2 is 2.

Step-by-step explanation:
Am marking the brainliest. Please help me solve this mathematics question.
Explanation:
Use the identity [tex]\sin{\theta} = 1 - \cos^2{\theta}[/tex] so we can write our equation as
[tex]6(1 - \cos^2{\theta}) - \cos{\theta} - 5 = 0[/tex]
or
[tex]6\cos^2{\theta} + \cos{\theta} - 1 = 0[/tex]
Let [tex]x = \cos{\theta}[/tex] so our equation becomes
[tex]6x^2 + x - 1 = 0[/tex]
Using the quadratic equation, we find that its roots are
[tex]x = \dfrac{-1 \pm \sqrt{(1)^2 - 4(6)(-1)}}{2(6)} = \dfrac{1}{3},\:-\dfrac{1}{2}[/tex]
which gives us
[tex]\cos{\theta} = \dfrac{1}{3} \Rightarrow \theta = 70.53°[/tex]
[tex]\cos{\theta} = -\dfrac{1}{2} \Rightarrow \theta = 120°[/tex]

Answer:
-3x + 6
Step-by-step explanation:
-3(x - 2) to find the equivalent of this expression, we need to multiply inside the parenthesis with -3 (with both x and -2)
-3(x - 2 = -3x + 6 (two negative expressions multiplied results in positive)
The area of a rectangle is 77 yd square, and the length of the rectangle is 3 yd more than twice the width. Find the dimensions of the rectangle.
Length :
Width :
Answer:
Length = 14 yd
Width = 5.5 yd
Step-by-step explanation:
Let width = x and length = 2x + 3
The formula for area is length x width.
(2x + 3) ( x ) = 77
2x² + 3x - 77 = 0
-77 x 2 = -154
What two numbers multiply to -154 and add to 3?
2x² + 14x - 11x - 77 = 0
2x (x + 7) - 11 (x + 7) = 0
(2x - 11) (x + 7) = 0
x = -7 (this isn't possible so ignore it)
x = 5.5 (width)
Now insert 5.5 into the initial equation.
2 (5.5) + 3 =
11 + 3 = 14
Answer:
Length is 3
width is 25•66
Step-by-step explanation:
Hope it helps!

Find (f o g)(x)
Consider f(x) = x + 7 and g(x) = x2 –1
Work Shown:
(f o g)(x) = f(g(x))
f(x) = x + 7
f( g(x) ) = g(x) + 7 ... replace every x with g(x)
f( g(x) ) = x^2-1 + 7 .... plug in g(x) = x^2-1
f( g(x) ) = x^2 + 6
(f o g)(x) = x^2 + 6

much will Chris owe in one year?
A. 18,014
B. 18,242
C. 18,360
D. 18,557
Answer:
18360
Step-by-step explanation:
A = P (1 + r/n)^(nt) where A is the amount in the account, P is the principle, r is the interest rate , n is the times compounded per year, t is the number of years
A = 17000 (1 + .08/1)^(1*1)
A = 17000( 1.08)^1
A = 18360

Answer:
x < -√3/2, x > √3/2, or -√1/2 < x < √1/2
Step-by-step explanation:
|1 - x^2| > 1/2
~Apply absolute value rule
1 - x^2 < -1/2 or 1 - x^2 > 1/2
~Simplify
x < -√3/2, x > √3/2, or -√1/2 < x < √1/2

Tamara rode her bicycle 8 miles in 0.5
hours. What was the average rate that
she rode her bicycle in miles per hour?
pls give me the step by step
Answer:
16 miles per hour (mph)
Step-by-step explanation:
Okay, so the beginning of the question states that Tamara rode her bicycle 8 miles in 0.5 hours.
0.5 is equivalent to 1/2 (one-half).
This means that she rode 8 miles in just half of an hour (30 minutes).
If she continues at this rate, she will have rode another 8 miles in the next 30 minutes.
And, 8 + 8 = 16.
Therefore, the average rate that she rode her bicycle is 16 miles per hour (mph).

BRAINLEST IF CORRECT!!!!
Answer: x = 5
Step-by-step explanation:
Given information
The combined angle is a right angle meaning it is 90°
Angle 1 = 8x°
Angle 2 = 50°
Set equation
Angle 1 + Angle 2 = Total angle
Substitute values into the equation
8x + 50 = 90
Subtract 50 on both sides
8x + 50 - 50 = 90 - 50
8x = 40
Divide 8 on both sides
8x / 8 = 40 / 8
x = 5
Hope this helps!! :)

Comparing Values Compare the values of the underlined digits. 1. The 4 in 3,492 and the 4 in 704
9514 1404 393
Answer:
4 in 3492 is 100 times 4 in 704
Step-by-step explanation:
To find the value of a particular digit, set the other digits to zero.
4 in 3492 = 400
4 in 704 = 4
The first 4 is 100 times the value of the second 4.
