Solve for P.
-1 + 14 p = -435
Answers
Answer:
P = -31
Step-by-step explanation:
-1 + 14p = -435
Remove the -1 by adding it from both sides.
14p = -434
Remove the 14 by dividing it from both sides.
p = -434/14
p = -31
Answer:
-31
Step-by-step explanation:
-1+14p=-435
14p=-435-(-1)
14p=-435+1
14p=-434
p=-434/14
p=-31

A printing company is enlarging the image on a postcard to make a greeting card. The enlargement of the postcard’s rectangular image is done using a scale factor of 125%. Be sure to show all other related math work used to answer the following questions.
(a)Represent a scale factor of 125% as a fraction and decimal.
(b)The postcard’s dimensions are 7 inches by 5 inches. What are the dimensions of the greeting card?
(c)If the printing company makes a poster by enlarging the postcard image, and the poster’s dimensions are 28 inches by 20 inches, represent the scale factor as a percent.
(d)Write an equation, in terms of the scale factor, that shows the relationship between the areas of the
postcard and poster. Explain your equation.
(e)Suppose the printing company wanted to start with the greeting card’s image and reduce it to create the postcard’s image. What scale factor would they use? Represent this scale factor as a percent.
(f). In math class, students had to create a scale drawing that was smaller than the postcard image. Azra
used a scale factor of 60% to create the smaller image. She stated the dimensions of her smaller image as 4 1/6 inches by 3 inches. Azra’s math teacher did not give her full credit for her answer. Why? Explain Azra’s error, and write the answer correctly

Answer:
x = 5
Step-by-step explanation:

169 - 144 = x^2
25 = x^2
[tex]\sqrt{25} = \sqrt{x^2}[/tex]
x = 5
Answer:
x = 5
Step-by-step explanation:
12² + x² = 13²
144 + x² = 169
144 - 144 + x² = 169 - 144
x² = 25
√x² = √25

Equation practice with angle addition
Answers
Answer:
m<BOC = 60°
Step-by-step explanation:
First, we will need to determine the value of x
m<BOC + m<AOB = m<AOC (angle addition postulate)
Substitute
9x + 42 + 7x + 30 = 104
Collect like terms
16x + 72 = 104
16x + 72 - 72 = 104 - 72
16x = 32
x = 32/16
x = 2
✔️m<BOC = 9x + 42
Plug in the value of x
m<BOC = 9(2) + 42
m<BOC = 18 + 42
= 60°
Find the volume of the sphere. Round your answer to the nearest tenth. Radius is 12ft
Answers
Answer: 7238.2[tex]ft^3[/tex]
Step-by-step explanation:
The formula for a sphere's volume is [tex]V=\frac{4}{3} \pi r^3[/tex].
Substitute r = 12 in the formula: [tex]V=\frac{4}{3} \pi (12)^3[/tex]
Then calculate (type the right side of the equation above in your calculator), and you will get an answer of 2304π. When you simplify further, you get 7238.22947. Rounded to the nearest tenth, it is 7238.2.
∴, the volume of the sphere is 7238.2[tex]ft^3[/tex], to the nearest tenth.
*note: it's [tex]ft^3[/tex] (feet cubed) because a sphere is a 3D object, so its volume is also a 3D measurement.

> sum of interior angles of a polygon is (n-2)·180°, where n-is the number of sides, so our rhombus has sum of angles =(4-2)·180° =360°
>we know that the opposite angles are congruent so ...
>we have the sum of interior angles is
108+108+7y-5+7y-5 = 360, combine like terms
14y +206 =360, subtract 206 from both sides
14y = 154, divide both sides by 14
y= 11
>the sides are congruent therefore
4x+17 = 8x-3 , subtract 4x, and add 3 from both sides
17+3 =8x-4x, combine like terms
20 = 4x , divide by 4 both sides

how many solutions does 3(4+x)=7x-2(2x+3) have
Answers
Answer: no solutions
Step-by-step explanation:
Let's solve your equation step-by-step.
3(4+x)=7x−2(2x+3)
Step 1: Simplify both sides of the equation.
3(4+x)=7x−2(2x+3)
(3)(4)+(3)(x)=7x+(−2)(2x)+(−2)(3)(Distribute)
12+3x=7x+−4x+−6
3x+12=(7x+−4x)+(−6)(Combine Like Terms)
3x+12=3x+−6
3x+12=3x−6
Step 2: Subtract 3x from both sides.
3x+12−3x=3x−6−3x
12=−6
Step 3: Subtract 12 from both sides.
12−12=−6−12

Which equation represents the relationship between the x-and y-values shown in the table.
x. y
7. 17
5. 11
3. 5
2. 2
A. y=2x-1
B. y=x + 10
C. y=3x -4
D. y=2x + 1
Answers
C. y = 3x - 4
Step-by-step explanation:
Given coordinates:
(2, 2), (3, 5), (5, 11), (7, 17)
The equation of any straight line is
y = mx + c
Where
m = Gradient
c = Constant
Gradient = y2 - y1/x2 - x1
Substitute any two values of y with the respective values of x.
Gradient = 17 - 2/7 - 2
= 15/5
= 3
Substitute the gradient into the general formula.
y = 3x + c
Substitute any value of the coordinate to the equation
2 = 3(2) + c
2 = 6 + c
c = -4
From y = mx + c,
substitute the values of m, the gradient, and c, the constant.
y = (3)x + (-4)
y = 3x - 4

Answer:
I would guess irrational, but Can you post a pic?
Step-by-step explanation:
The result of 4√5 + 3√2 is an irrational number because it contains the irrational term 7√5, which cannot be written as the ratio of two integers and does not have a terminating or repeating decimal expansion.
What is a rational number?A rational number is defined as a numerical representation of a part of a whole that represents a fraction number.
The number is given in the question as follows:
4√5 and 3√2
We have to determine the sum of 4√5 and 3√2.
To find the sum of 4√5 and 3√2 , we can simply add the two terms:
⇒ 4√5 + 3√2
⇒ (4 + 3)√5 + 0√2
⇒ 7√5
In conclusion, the result of 4√5 + 3√2 is an irrational number because it contains the irrational term 7√5, which cannot be written as the ratio of two integers and does not have a terminating or repeating decimal expansion.
