Answer:
x = 60
Step-by-step explanation:
x/12 is the same as 1/12x
so now the equation is 1/12x+1=6
then to simplify it even more we do -1 from both sides so
1/12x+1=6
-1 -1
again the equation is 1/12x=5
then we multiply both sides by 12 and get x = 60
Solve the given quadratic equation 2x2 + x + 1 = 0.

What is 9m + 6 = 87
please help im desperate fwhe
Answer:
m=9
Step-by-step explanation:
9m=81
Answer:
9
Step-by-step explanation:
First you have to get the variable by its self (m). So you will get rid of 6 and since it’s positive you will do negative 6 to cancel it out. But what you do to one side you do to the other, so you will do 87 - 6 and get 81. Now it’s 9m = 81. So then since 9 is next to m that implies multiplcation so you do the opposite of multiplication and dived 9 by both sides. And when you do that you get 9.

The price of a technology stock has dropped to $9.63 today. Yesterday's price was 89.76. Find the percentage decrease. Round your answer to the nearest
tenth of a percent.
Answer:
1.33%
Step-by-step explanation:
[tex]Percentage\ change=(\frac{9.76-9.63}{9.76})100\\\\Percentage\ change=(\frac{0.13}{9.76})100\\\\Percentage\ change=1.33\\[/tex]
So the percentage decrease was about 1.33%

three proportional sides
20.The mid-segment SR of triangle, which joins the midpoints of two sides of triangle, is parallel to the third side of the triangle and half the length of that third side of the triangle.
So s the sides of triangle SFR and GFH are proportional.
21.AAA
two pairs of corresponding angles are congruent and angle B is common.
22.they are not similar because pairs of corresponding angles are not congruent.
96 is not equal to 97 also even not proportional.
23.
x=10
explanation:sides are proportional
26/13=2
so
22/2=11 and 11=2x-9 2x=11+9=20 x=20/2=10
24.
x=11
Because it is given that each pair is similar then we have proportional sides but FM=MG=20 so
LM=MK
50=4x+6
4x=44
x=11

Answer:
25.734
Step of explanation:
tanjent =opposite/adjacent
cosine =adjacent /hypotenuse
sine =opposite /hypotenuse
this use tangent because the opposite number is there and we want to find adjacent
so t =opposite /adjacent
tan25 °=12/ a
a=12/tan25

Find the slope of the line through each pair of points (-17, 11) , (-12, 9) 
Answer:
M = -2/5
Step-by-step explanation:
To find the slope of a line when you know two points, use the following formula.
M = y₂ - y₁ ÷ x₂ - x₁
M = 9 - 11 ÷ -12 - (-17)
M = -2 ÷ 5
M = -2/5

X^3 = 1,000
algebratic equations
Answer:
10
Step-by-step explanation:
x³=1000
x=3√1000
x=10
Answer:
x = 10 or x = -5 + 5*i*sqrt(3) or x = -5 - 5*i*sqrt(3)
Step-by-step explanation:
x^3 = 1000
x^3 - 1000 = 0
(x - 10)(x^2 + 10x + 100) = 0
x = 10 or x^2 + 10x + 100 = 0
x = 10 or x^2 + 10x + 25 = -100 + 25
x = 10 or (x + 5)^2 = -75
x = 10 or x + 5 = sqrt(-75) or x + 5 = -sqrt(75)
x = 10 or x = -5 + 5*i*sqrt(3) or x = -5 - 5*i*sqrt(3)

Beverly made a root beer float using 1/4 cup of vanilla ice cream for every 3/4 cup of root beer. how much ice cream would Beverly need for one cup of root beer?
Answer:
1/3 cup of ice icream
Step-by-step explanation:
This is a proportions question. Since we know that we need 1/4 cup of ice cream for every 3/4 cup of root beer, we need to find how many cups of ice cream we need for 1 cup of root bear.
We need to find out what times 3/4 makes 1. This can be done with:
(3/4)x = 1
x = 4/3
Now multiply that with 1/4 to get the amount of ice cream.
4/3 times 1/4 = 1/3

Answer:
2250 m
Step-by-step explanation:
30 cm = 0.3 m
1 : 75 :: 0.3 : x
Product of extremes = product of means

x = 75 * 0.30
x = 22.5 m
Answer:
22.5 m
Step-by-step explanation:
Convert to meters
.3 / x = 1/75
multiply .3 by 75 to get 22.5 m

Write the equation of the line that passes through the points (-9,-4) and (-9,4).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
x = -9
Step-by-step explanation:
x = -9 would be the slope because when you see the two points for each coordinate there is no x value but we do see a straight line and we see that there is no y-intercept. So, x= -9 would be the answer. Hope this helps.

Sean is getting balloons for his grandfather's birthday party. He wants each balloon string to be 9 feet long. At the party store, string is sold by the yard. If Sean wants to get 66 balloons, how many yards of string will he need?
Answer:
198 yards
Step-by-step explanation:
Sean wants the sting of each balloon to be 9 feet, and he wants to get a total of 66 balloons.
The total length of stings required for 66 balloons would be;
total length of balloon strings = 66 x 9 feet
= 594 feet
But the string is sold by the yard at the store.
So that,
1 yard = 36 inches = 3 feet
x yard = 594 feet
Thus,
x = [tex]\frac{594}{3}[/tex]
= 198 yards
x = 198 yards
Therefore, the total length of string that Sean would need is 198 yards.
What is the length of x in the diagram below?
A triangle with vertical bisector forms 2 triangles with a right angle. One triangle has a side length of 5 and another angle with a measure 45 degrees. Another triangle has a hypotenuse with length x and another angle with measure 30 degrees.
StartFraction 5 Over StartRoot 3 EndRoot
StartFraction 10 Over StartRoot 3 EndRoot EndFraction
5 StartRoot 3 EndRoot
10
Answer:
That is a 45-45-90 triangle next to a 30-60-90 triangle.
So, the height of the left triangle equals 5.
That makes the short side of the 30-60-90 triangle also equal to 5.
In a 30-60-90 triangle, the hypotenuse (or "x") is exactly twice the length of the shortest side.
Therefore, the hypotenuse (or "x") equals 10.

what is the coefficient of -4(4t^2+4t+1)
Answer:
So 2t%5E2%2B4t-30 completely factors to 2%28t%2B5%29%28t-3%29.
In other words, 2t%5E2%2B4t-30=2%28t%2B5%29%28t-3%29.
Note: you can check the answer by expanding 2%28t%2B5%29%28t-3%29 to get 2t%5E2%2B4t-30 or by graphing the original expression and the answer (the two graphs should be identical).

Answer:
m∠4 = 55°
Step-by-step explanation:
From the figure attached,
m∠DBC = m∠BCA + m∠BAC [Exterior angle of a triangle equals the sum of the remote interior angles]
m∠4 = 30° + 25° = 55°
Therefore, m∠4 = 55° will be the answer.
What is the equation in point−slope form of the line passing through (1, 2) and (2, 5)? (5 points) Group of answer choices (y − 1) = −3(x − 2), (y + 2) = 3(x + 1,) (y − 2) = 3(x − 1), (y − 2) = −3(x − 1)
Answer using slope formula:
[tex]\frac{y2-y1}{x2-x1}[/tex]
We can find the slope.
Substitute:
[tex]\frac{5-2}{2-1}[/tex]
Subtract:
[tex]\frac{3}{1}[/tex]
[tex]\frac{3}{1}= 3[/tex]
Our slope is 3.
Now we will use Point Slope formula:
[tex]y-y1=m(x-x1)[/tex]
To find our equation.
I will use the first ordered pair, (1,2).
Substitute:
[tex]y-2=3(x-1)[/tex]
Your answer is C. (y − 2) = 3(x − 1).
Hope this helped! :)
