Answer:
x = 7.5
Step-by-step explanation:
Use algebraic manipulation (and remember that anything you do to one side must be done to the other, in most cases):
34 + 2x = 49
-34 -34
2x = 49 - 34
2x = 15

Which of the following situations are equal to 75%? Select all that apply.
A) 9 out of 12
B) 27 out of 36
C) 4 out of 8
D) 60 out of 80
E) 15 out of 25
Answer:
A) 9 out of 12
Step-by-step explanation:
The first step is to divide 9 by 12 to get the answer in decimal form:
9 / 12 = 0.7500
Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage:
0.7500 * 100 = 75.00%
We can prove that the answer is correct by taking 75.00 percent of 12 to get 9:
(12 x 75.00)/100 = 9
0.075538 to 2 decimal place
0.081770 to 3 significant figure
Answer:0.08

can anyone solve this?
6÷2(1+2)=
Answer:
9
Solving steps:
=> 6÷2(1+2)
divide 6 by 2
=> 3(1+2)
add values inside the bracket
=> 3(3)
multiply 3 by 3
=> 9
Answer:
9
Step-by-step explanation:
Use parenthesis, exponents, multiplication, division, addition, and subtraction, witch stands for PEMDAS.
1. 1+2 is the first step, since it is in the parenthesis. This gives you 3
2. You do 6÷2, since that is the next step. Since the operations are from left to right , you move on the next step, witch is divison. This also gives you 3.
3. You do the final step, witch is to multiply, so you do 3 x 3 , witch gives you 9.

Answer:
x = 60 degrees.
Step-by-step explanation:
The sides are all equal to one another, so that means that it is an equilateral triangle. An equilateral triangle's angle measures are always 60 degrees.
[tex]Hello,BrainlyUser][/tex]
Answer:
x = 60
Step-by-step explanation:
Since the triangle in the picture is a equilateral triangle. If you don't know what a equilateral triangle.. I will explain to you; An equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
Thus, we can infer that x = 60.

You are working with the Cosine of the angle.
Hypotenuse = 12.5
Base = 3
Theta = ?
Solution
Cos(theta) = base / hypotenuse Substitute values
Cos(theta) = 3 / 12.5 Divide
Cos(theta) = 0.24 Tale the inverse cos
theta = cos-1(0.24)

) Turner helped his grandfather build a raised garden bed for Turner's grandmother. The
bed is shaped like a rectangular prism that is 4 1/2 feet wide and 1/2 of a foot tall. Turner and his
grandfather used 18 bags of topsoil, each containing 3/4 of a cubic foot, to fill the bed
completely.
How long is the garden bed?
1) Write your answer as a whole number, proper fraction, or mixed number.
The length of the garden bed is 6 feet
The volume of a rectangular prismThe formula for calculating the volume of a rectangular prism is expressed as:
V = lwh
If turner and his grandfather used 18 bags of topsoil, each containing 3/4 of a cubic foot, to fill the bed completely, hence;
V = 3/4 * 18
V = 13.5 cubic foot
In order to determine the length of the garden;
135/10 = 9/2 * 1/2l
27/2 =9/4 l
18l = 27 * 4
18l = 108
l = 6 feet
Hence the length of the garden bed is 6 feet

Answer:
[tex]\sf x = 5[/tex][tex]\sf DF = 12[/tex]setting up proportionality equation:
[tex]\sf \dfrac{big-side}{big-diagonal} = \sf \dfrac{small-side}{small-diagonal}[/tex]
[tex]\sf \hookrightarrow \dfrac{7}{16+x+7} = \dfrac{4}{16}[/tex]
[tex]\sf \hookrightarrow \dfrac{7}{23+x} = \dfrac{4}{16}[/tex]
[tex]\sf \hookrightarrow 4(23+x) = 112[/tex]
[tex]\sf \hookrightarrow 92 + 4x = 112[/tex]

Find DF:
[tex]\hookrightarrow \sf x + 7[/tex]
[tex]\hookrightarrow \sf 5 + 7[/tex]
[tex]\hookrightarrow \sf 12[/tex]
Answer:
We see 2 congruent triangles: Triangle DBC and FEC. Let's set up a proportion to find the value of x and length of DF.
[tex]\frac{BE+EC}{DF+FC} =\frac{EC}{FC}[/tex]
[tex]\frac{3+4}{(x+7)+16} =\frac{4}{16}[/tex]
Cross multiply and solve for x.
[tex](3+4)*16=((x+7)+16)*4[/tex]
[tex]7*16=(x+23)*4[/tex]
[tex]112=(x+23)*4[/tex]

x= 5
Now to solve for the length of DF, plug in x into DF.
DF=(x+7)
DF=(5+7)
DF= 12
Let f(x)=3x^2+2.
The equation g(x) is f(x) translated up 5 units.
What is the equation of g(x)?
Answer:
g(x) = 3x² + 7
Explanation:
Here the f(x) is translated up 5 units, so we shall increase y axis by + 5
so new equation: g(x) = 3x² + 2 + 5 ➛ g(x) = 3x² + 7
check the image given below. The red line is f(x) and blue line g(x)Answer:
g(x) = 3x² + 7
Step-by-step explanation:
If a function is translated 5 units up then:
g(x) = f(x) + 5
⇒ g(x) = 3x² + 2 + 5
⇒ g(x) = 3x² + 7

Desmond is rowing a standard six sided number cube times how many times Would he roll a 5 or a 6
A rectangle has an area of (4x2 + 10) square inches. The length of the rectangle is (2x2 + 5) inches.
How many inches is the width of the rectangle?
Answer:
Area of the rectangle = 4x^2+8x = 4x(x+2)
So if the length is (x+2), the width of the rectangle = 4x(x+2)/ (x+2) = 4x.
The length is > the width, so
x+2 > 4x, or
2 > 3x, or
(2/3) > x or
x < (2/3).
Say x = 5/9 which is < 2/3, the length = 2 + 5/9 or 23/9 and the width =20/9, which is logical.

The Trinomial [tex]\rm 2x^{2} +13x+6[/tex] has a linear factor [tex]\rm (x+6)[/tex] and the other linear factor is [tex]\rm (2x+1)[/tex].
The Trinomial [tex]\rm 2x^{2} +13x+6[/tex] has a linear factor [tex]\rm (x+6)[/tex]. we need to find another linear factor say X.
[tex]\rm 2x^{2} +13x+6 = \rm (x+6)(X)[/tex]
what is a linear factor?The linear factor of the polynomial is the first-degree polynomial equations represented as [tex]\rm ax+b[/tex] and cannot be factored further.
So, the other factor X can be calculated as,
[tex]\rm 2x^{2} +13x+6 = \rm (x+6)(X)\\\rm 2x^{2} +13x+6\div \rm (x+6)=X\\\rm (x+6)\times \rm (2x+1)\div \rm (x+6)=X\\X=\rm (2x+1)[/tex]
