Answer:
C . 4
Step-by-step explanation:
step 1 : -3 multiply with inside of the ( 7x-5 )
= -21x + 15
step 2 : then it will be 21x + 15 = 87 + 3x
step 3 : switch between the odds into like this
21x - 3x = 87 - 15
step 4 : subtract it all
18x = 72
step 5 : bring 18 to the other side
x = 72/18
step 6 : to find the ans of x is just calculate them
x = 72 ÷ 18
= 4
Or you can do like these ⬇️
-3 ( 7x - 15 ) = 87 + 3x
21x + 15 = 87 + 3x
21x - 3x = 87 - 15
18x = 72
x = 72/18 or 72÷18
x = 4
A 24 foot flagpole casts a shadow. The distance along the ground from the base of the pole to the tip of the shadow is 9 feet. What is the distance from the top of the pole to the tip of the shadow (nearest tenth)?
Answer:
9.4 feet to the nearest tenth.
Step-by-step explanation:
This makes a right triangle so we use Pythagoras:
23^2 = 21^2 + d^2 where d is the required distance.
d^2 = 23^2 - 21^2
d^2 = 88
d = √88 = 9.3808

Question how do I find the value of x?
Answer:
20
Step-by-step explanation:
The total degrees in a circle is 360 degrees
x+40+2x+110+3x+90 = 360
==> 6x = 120
x = 20
Answer:
The answer would be x=20
ASAP PLEASE HELP
LOOK AT THE PICTURE
Answer:
Step-by-step explanation:
Sin(x) = opposite / hypotenuse.
opposite = 28 The opposite is not connected to the angle.
hypotenuse= 35
Sin(x) = 28/35 = 4/5
Cos(x) = adjacent / hypotenuse.
The adjacent side is part of the angle
adjacent = 21
hypotenuse = 35
Cos(x) = 21 / 35 = 3/5
Tan(x) = opposite / adjacent
opposite = 28
adjacent = 21
Tan(x) = 28/21
Tan(x) = 4/3
Find the lateral area of this cone, leave your answer in terms of pi. hight-12, radius-5
Answer:
Just search up Mathaway in your browser and it will give you the answer and a step by step explanation
Step-by-step explanation:
Answer:
The answer is 65
Step-by-step explanation
You need the slant height to find the lateral area of the cone, so using the equation l = √h²+r², you plug in the height for h, the radius for r, and l is the slant height.
l =√12²+5²
l = √144 + 25
l = √169
l = 13
Now that you have the slant height, simply multiply that by the radius and you'll get the lateral area in terms of pi.
A = π×13×5
A = 65π

-4 + x = 3
Find the value of x.
Answer:
x = 60
Step-by-step explanation:
Remark
The two angles that are equal are remote interior angles. They add to 120
Step one
y + y = 120 Combine
2y = 120 Divide by 2
y = 120/2
y = 60
Step Two
Find the angle vertically opposite to the 60 degree angle near the center on the left hand triangle.
The vertically opposite angle is 60. If you know one vertically opposite angle, you know the other one.
Step Three
State the value of the angle that is vertically opposite x.
The angles value is 60o. You are working with an isosceles triangle according to the markings on the triangle.
Step Four
State the value of x
The value of x = 60 degrees. It is equal to the angle described in step three.

According to the weather channel, the chance of rain on Tuesday, February 23rd is 6%. It's complement is %.
Answer:
It's complement is 94%.
Step-by-step explanation:
Complement of a percentage:
The complement of a percentage is 100% subtracted by this percentage.
In this question:
Percentage of 6% for probability of rain.
So the complement, that is, the probability of not raining, is:
100 - 6 = 94%.
Simply each expression completely and you can use the power to power rule to solve this
Answer:
c = 240
Step-by-step explanation:
Using the rule of exponents
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]
Then
[tex](a^{40}) ^{6}[/tex]
= [tex]a^{40(6)}[/tex] = [tex]a^{240}[/tex]
A board with 86cm in length must be cut so that one piece is 20cm longer than the other piece .find the length of each piece
Answer:
33cm ; 53 cm
Step-by-step explanation:
Let the length of one piece = x cm
Length of the other piece = (x + 20) cm
x + ( x+ 20) = 86 cm
x + x + 20 = 86
2x + 20 = 86
2x = 86- 20
2x = 66
x = 66/2
x = 33 cm
Length of the longer piece = x + 20 = 33 +20 = 53 cm

what strategy can be used to transform a quadratic function in vertex form to standard form
Hello, I Am BrotherEye
Answer:
This Transparent inquisition can be solved Below
Use transformations to graph a quadratic function in vertex form. A quadratic function in standard form, f(x) = ax² + bx + c, can be changed into vertex form by completing the square. The vertex form of a quadratic function is f(x) = a(x – 5)2 + k, where the vertex of the function is (h, k).
Step-by-step explanation:
Vertex form to standard form converter
Write the parabola equation in the vertex form: y = a*(x-h)² + k ;
Expand the expression in the bracket: y = a*(x² - 2*h*x + h²) + k ;
Multiply the terms in the parenthesis by a : y = a*x² - 2*a*h*x + a*h² + k ;
Best Of Luck

Which set of measurements determines more than one triangle?
Answer:80,65,20
Step-by-step explanation:
In general, a unique triangle may always be drawn if three side lengths are given and the sum of any two is greater than the third. c) More than one triangle can be drawn with Angle A = 40°, Angle B = 60° and Angle C = 80°. The angles sum to 180°, so at least one triangle may be drawn.

Find X to solve to problem and find all the angles
Answer:
Step-by-step explanation:
x + x + 65 °+ 25° = 180° ( being sum of angles of triangle )
2x + 90° = 180°
2x = 90°
x = 45
now
<A = 45°
< B = x + 65° = 45 °+ 65 °= 110°
< C = 25°
Hope it helps :)
