Three is added to a number, and the sum is multipled by 4. What is the equation and answer? Explain too please.
Answer:
3+X=[3+X]4
Step-by-step explanation:
Let the number be X
we add x by three = 3+x
the sum of 3+x is 3+x
so we multiply the whole sum by 4 which is [3+x]4
so the ans is 3+x=[3+x]4

BRAILYEST The area of a square poster is 37 in.2. Find the length of one side of the poster to the nearest tenth of an inch. The length of one side of the poster is nothing in.
Answer:
Length of the square poster = 6.1 in
Step-by-step explanation:
Area of a square poster = 37 in^2
Area of a square = length^2
37 = lenght ^2
Find the square root of both sides
√37 = √ length ^2
Length = 6.0828 in
Approximately
Length of the square poster = 6.1 in

The ratio of red marbles to blue marbles is 3:5. If there are 225 blue marbles total in the collection, how many of each color are there? Please show your work.
Answer:
Red balls = 84 Blue balls = 140
Step-by-step explanation:
Ok so there are 225 marbles
And ratio here is Red : Blue = 3 : 5
So Red marbles = 3x whereas Blue marbles = 5x
Therefore,
3x + 5x = 225
8x = 225
x = 28.125 = 28
Red balls = 28*3 = 84 Blue balls = 28*5 = 140
(Pls check whether total no of balls is 224)

PLZ HELP!!!! A pair of equations is shown below: y = 6x − 4 y = 5x − 3 Part A: In your own words, explain how you can solve the pair of equations graphically. Write the slope and y-intercept for each equation that you will plot on the graph to solve the equations. (6 points) Part B: What is the solution to the pair of equations? (4 points)
Answer:
Step-by-step explanation:
y = 6x − 4
y = 5x − 3
A: chose a value for x(input) and get the out put (y) because the equation already in the slope intercept mode:y=mx+b
x y=6x-4 y=5x-3

2 y=8 y=7
0 -4 -3
slope :
y=6x-4 slope is 6 y intercept(0,-4)
y=5x-3 slope is 5 y intercept (0,-3)
solution of the pair of equation is the point of intersection :
6x-4=5x-3

Pete’s Painting Company will charge a one-time fee of $60 for labor and $20 for each room painted. Carla’s Creative Colors will charge $40 a room but only $20 to hire workers. Write a function rule for Pete’s Painting Company in function notation. Write a function rule for Carla’s Creative Colors in function notation.
Answer:
Pete's: [tex]f(x) = 20x + 60[/tex]
Carla's: [tex]f(x) = 40x + 20[/tex]
Step-by-step explanation:
Let's assume that [tex]x[/tex] is the amount of rooms painted, and [tex]f(x)[/tex]
For Pete's Painting Company, they charge a flat fee of $60, so we will have a constant of 60.
They also charge 20$ per room, meaning that we will multiply 20 by [tex]x[/tex], the amount of rooms painted.
This gets us the function [tex]f(x) = 20x + 60[/tex]
For Carla's Creative Colors, they charge 20$ to hire the workers, meaning this will be our constant.
They also charge $40 a room, meaning we will multiply 40 by [tex]x[/tex], the amount of rooms painted.
So the function is [tex]f(x) = 40x + 20[/tex].

if tanA+cotA=2 then find the value of cosA
Answer:
cos A=
[tex] \frac{1}{ \sqrt{2} } [/tex]
Step-by-step explanation:
We know,
cotA=
[tex] \frac{1}{ \tan(a) } [/tex]
Substituting the value of cot A in the given equation, we get
[tex] \tan( a) + \frac{1}{ \tan(a) } = 2[/tex]
[tex] \frac{{ \tan }^{2} a + 1}{ \: \tan(a) } = 2[/tex]
[tex] { \tan }^{2 \: } a \: + 1 = 2 tan \: a[/tex]
[tex] { \tan }^{2} a - 2 \tan \: a + 1 = 0[/tex]
[tex]( \tan \: a - 1) {}^{2 } = 0[/tex]
[tex] \tan \: a - 1 = \sqrt{0} [/tex]
[tex] \tan \: a = 1 [/tex]
[tex] \tan \: a \: = \tan \: 45[/tex]
[tex]a = 45[/tex]
[tex] \cos \: a = \cos \: 45[/tex]
[tex] \cos \: a = \frac{1}{ \sqrt{2} } [/tex]
a carpenter has a wooden dowel that is 96 cm long. she wants to cut it into two pieces so that one piece is 5 times as long as the other. what is the length of the longer piece?
Answer:
30 cmStep-by-step explanation:
In this problem (word problem), we are examined on how to express equations from words.
let us initialize some variables
let the length of the first piece (the short piece) be x
and that of the second(the longer piece) be 5x
given that the total length is 96 cm
Also from the problem statement, the total length can be expressed as
5x+x= 96
6x= 96
divide both sides by 6 to solve for x
x= 96/6
x= 16
now the longer side = 5x
the longer side= 5*6
the longer side = 30 cm

Then we can plug back in to find the numbers.

[tex]3*7=21[/tex]

Step-by-step explanation:
Beth is solving this equation: 1/x + 3 =3/x
she says "I can multiply both sides by X and get the linear equation 1 + 3x = 3 whose solution is x = 2/3 ."
which of the following statements makes this a correct argument, or shows that it is in correct? Select all that apply.
a. you cannot multiply both sides by x because you do not know what x is.
b. you can assume x = 0 because both sides are undefined if x = 0
c. after multiplying both sides by X you need to subtract 1 from both sides.
d. the equation is not linear, so you cannot use the methods normally used for solving linear equations.
Answer:
a. you cannot multiply both sides by x because you do not know what x is.
Step-by-step explanation:
Given:
[tex]\frac{1}{x} + 3 = \frac{3}{x}[/tex]
Required
Select which of the option that applies
Considering (a):
A is incorrect:
Because: Multiplying both sides by x has nothing to do with whether the value of x is known or not
Considering (b):
B is incorrect:
Substitute 0 for x in the given expression
[tex]\frac{1}{0} + 3 = \frac{3}{0}[/tex]
[tex]Und efi ned[/tex]
Both sides of the equation are undefined
However, you cannot assume x to be 0
Considering (c):
C is correct:
Start by multiplying both sides by x
[tex]x (\frac{1}{x} + 3) = \frac{3}{x} * x[/tex]
[tex]1 + 3x = 3[/tex]
Then, subtract 1 from both sides
[tex]1 - 1 + 3x = 3 - 1[/tex]
[tex]3x = 2[/tex]
Divide through by 3
[tex]x = \frac{2}{3}[/tex]
Considering (d):
D is incorrect;
Because, the equation is linear
if the sides of a triangle are produced in order prove that the sum ofexterior angles so formed is equal to four right angles
Step-by-step explanation:
Let a, b, c be the measures of the interior angles and x, y, z be the measures of the exterior angles of the triangle. Where x and adjacent to a, y is adjacent to b and z is adjacent to c.
By interior angle sum postulate of a triangle:
a + b + c = 180°... (1)
Therefore, by remote interior angle theorem:
x = b + c.... (2)
y = a + c..... (3)
z = a + b.... (4)
Adding equations (2), (3) & (4)
x + y + z = b + c + a + c + a + b
x + y + z = 2a + 2b + 2c
x + y + z = 2(a + b + c)... (5)
From equations (1) & (5)
[tex]x + y + z = 2 \times 180 \degree \\ x + y + z = 360 \degree \\ x + y + z = 4 \times 90\degree \\ x + y + z = 4 \: right \: angles[/tex]
Thus, the sum of exterior angles so formed is equal to four right angles.
