Half of a number x is equal to 9 less than 2 times that same number. What is the
number
Answer:
[tex]x = 6[/tex]
Step-by-step explanation:
Analyzing the statement one after the other:
Half a number x: [tex]\frac{1}{2}x[/tex]
Equals to: [tex]=[/tex]
9 less than twice that same number: [tex]2x - 9[/tex]
Bring them together, we have:
[tex]\frac{1}{2}x = 2x-9[/tex]
Collect Like Terms
[tex]\frac{1}{2}x - 2x= -9[/tex]
[tex]\frac{x}{2} - 2x= -9[/tex]
[tex]\frac{x - 4x}{2} = -9[/tex]
[tex]\frac{ - 3x}{2} = -9[/tex]
Multiply through by 2
[tex]2 * \frac{ - 3x}{2} = -9 * 2[/tex]
[tex]- 3x = -18[/tex]
Divide through by -3

Marco volunteered to help with a home remodeling project at his grandparents' house, but he also needs to study to maintain good grades. He decided he can spend no more than 36 hours on painting walls and framing windows. He needs 2
hours to paint a wall and 3 hours to frame a large window. Write an inequality to represent the constraints.
Answer:
2w + 3x ≤ 36
Step-by-step explanation:
Given that :
Hours needed to paint wall = 2 hours
Hours required to frame window = 3 hours
Total hours to spend ≤ 36
Let :
Number of walls to paint = w
Number of windows to frame = x
Hence,
Hours required to paint a wall * number of waas to paint) + (hours required to frame a window * Number of windows to frame.)
(2*w) + (3*x) ≤ 36
2w + 3x ≤ 36
You are given that cos(A)=15/17, with A in Quadrant IV, and cos(B)=4/5, with B in Quadrant IV. Find cos(A−B). Give your answer as a fraction.
Please help i need this asap.
Answer:
4/5
Step-by-step explanation:
There are four quadrants in a coordinate geometry.
The value of cos(A - B) is 84/85
The given parameters are:
[tex]\mathbf{cos(A) = \frac{15}{17}}[/tex]
[tex]\mathbf{cos(B) = \frac{4}{5}}[/tex]
Using trigonometry ratio, we have:
[tex]\mathbf{sin^2(A) + cos^2(A)= 1}[/tex]
Substitute [tex]\mathbf{cos(A) = \frac{15}{17}}[/tex]
[tex]\mathbf{sin^2(A) + (\frac {15}{17})^2 =1}[/tex]
Expand
[tex]\mathbf{sin^2(A) + \frac{225}{289} =1}[/tex]
Collect like terms
[tex]\mathbf{sin^2(A) =1 - \frac{225}{289}}[/tex]
Evaluate fraction
[tex]\mathbf{sin^2(A) =\frac{64}{289}}[/tex]
Take square roots of both sides
[tex]\mathbf{sin(A) =\pm\frac{8}{17}}[/tex]
The angle is in the fourth quadrant.
So, we have:
[tex]\mathbf{sin(A) =-\frac{8}{17}}[/tex]
Also,
Substitute [tex]\mathbf{cos(B) = \frac{4}{5}}[/tex] in [tex]\mathbf{sin^2(B) + cos^2(B)= 1}[/tex]
[tex]\mathbf{sin^2(B) + (\frac 45)^2= 1}[/tex]
[tex]\mathbf{sin^2(B) + \frac{16}{25}= 1}[/tex]
Collect like terms
[tex]\mathbf{sin^2(B) = 1 - \frac{16}{25}}[/tex]
Simplify fraction
[tex]\mathbf{sin^2(B) = \frac{9}{25}}[/tex]
Take square roots
[tex]\mathbf{sin(B) = \pm \frac{3}{5}}[/tex]
The angle is also in fourth quadrant
So, we have:
[tex]\mathbf{sin(B) = - \frac{3}{5}}[/tex]
To calculate cos(A - B), we make use of:
[tex]\mathbf{cos(A - B) = cos(A)cos(B) + sin(A)sin(B)}[/tex]
So, we have:
[tex]\mathbf{cos(A - B) = \frac{15}{17} \times \frac{4}{5} + \frac{-8}{17} \times \frac{-3}{5}}[/tex]
Evaluate
[tex]\mathbf{cos(A - B) = \frac{60}{85} + \frac{24}{85}}[/tex]
Take LCM
[tex]\mathbf{cos(A - B) = \frac{60+24}{85}}[/tex]
[tex]\mathbf{cos(A - B) = \frac{84}{85}}[/tex]
Hence, the value of cos(A - B) is 84/85

13w + 9 = 178
What’s the first step in solving this equation
Step-by-step explanation:
I don't know if you do this the same way I did, but..
The first step is to subtract 9 on both sides, like this.
13w + 9 = 178
-9 -9
You'll end up with:
13w = 169
I don't know if you need the answer or not but I'll help you out.
For the second step, divide both sides by 13w.
13w = 169
/13w /13w
w = 13
Hope this helped!
Answer:
The first step is that you have to subtract 9 from both sides and you are left with 13w=169 now divide both sides by 13 and you get 13 as your answer.

A company has a target to reduce the number of its stores by 40% over the next two years. At the end of the first year it has reduced the number of its stores by 20% If the company is going to reach its target, it must reduce the number of its stores
Answer:
by 25%
Step-by-step explanation:
We can assume that the company originally had 100 stores and it plans to keep only 60 open after two years. If it was able to close 20 stores during the first year, the total number of stores remaining open was 100 - 20 = 80. Since it needs to decrease the number of stores to 60, it must reduce the number of stores by 20/80 = 0.25 or 25%.

4x−3y=−4
Answer:
[tex]D)\ -1,0[/tex]
Step-by-step explanation:
Given
[tex]4x - 3y= -4[/tex]
Required
Determine which of the options is on the line
The question requires options.
However, I'll answer using the following:
[tex]A) -3, 4[/tex]
[tex]B) -4,3[/tex]
[tex]C)\ 3, 4[/tex]
[tex]D)\ -1,0[/tex]
A point is always of the form (x,y).
So, we have to substitute values for x and y in the given equation
Considering option A:
[tex](x,y)= (-3,4)[/tex]
Substitute [tex]-3\ for\ x\ and\ 4\ for\ y[/tex] in [tex]4x - 3y= -4[/tex]
[tex]4(-3) -3(4) = -4[/tex]
[tex]-12 -12 = -4[/tex]
[tex]-24 \neq -4[/tex]
The above represents an inequality.
Hence, -3,4 does not lie on the equation
Considering option B:
[tex](x,y) = (-4,3)[/tex]
Substitute [tex]-4\ for\ x\ and\ 3\ for\ y[/tex] in [tex]4x - 3y= -4[/tex]
[tex]4(-4) - 3(3) = -4[/tex]
[tex]-16 - 9 = -4[/tex]
[tex]-25 \neq -4[/tex]
The above represents an inequality.
Hence, -4,3 does not lie on the equation
Considering option C:
[tex](x,y) = (3,4)[/tex]
Substitute [tex]3\ for\ x\ and\ 4\ for[/tex] y in [tex]4x - 3y= -4[/tex]
[tex]4(3) - 3(4) = 4[/tex]
[tex]12 - 12 = 4[/tex]
[tex]0 \neq 4[/tex]
The above represents an inequality.
Hence, 3,4 does not lie on the equation
Considering Option D:
[tex](x,y) = (-1,0)[/tex]
Substitute [tex]-1\ for\ x\ and\ 0\ for[/tex] y in [tex]4x - 3y= -4[/tex]
[tex]4(-1) - 3(0) = -4[/tex]
[tex]-4 - 0 = -4[/tex]
[tex]-4 = -4[/tex]
The above represents an equality.
So, -1,0 lies on the equation
Solve the inequality W > Y Plus H all divided by P for H
Answer:
W - Y > H
Or
H < W - Y
Step-by-step explanation:
From the word problem/ information given from the problem, we can formulate a full inequality:
[tex]\frac{W > Y+H}{P}[/tex]
And we are trying to solve for H:
What we must do is solve by following the process of PEMDAS
P - () (Parenthesis)
E - [tex]x^{2}[/tex] (Exponents)
M - x (Multiply)
D - [tex]\frac{x}{y}[/tex] (Division)
A - + (Addition)
S - [-] (Subtraction)
1) Look through PEMDAS until you notice one:
We find that there is Division!
In order to get one step closer to finding H, we must do the opposite of dividing which is multiplying:
P([tex]\frac{W > Y+H}{P}[/tex])
This will cancel out P, leaving you with:
[tex]{W > Y+H}[/tex]
2) Now we must get H alone by subtracting Y on both sides:
[tex]{W > Y+H}\\[/tex]
-Y - Y
---------------
W - Y > H
Your final answer is W - Y > H

The shortest distance from a line to the center of a circle of a radius 4 units is 12 units. The circle is reflected across the line. What is the radius of the resulting image?
Answer: The radius will still be 4 units.
Step-by-step explanation:
Since it is a rigid transformation, nothing of the shape will change excepts it location meaning that the radius of the shape will still stay the same.
The radius is 4 and after a reflection , the radius will still be 4.

Answer:
12x-11
Step-by-step explanation:
There is no known solution, but this can be simplified. Add up all of the coefficients(# connected by the variable). Since after 7x is a - , the x following has to be negative. After adding the coefficients, you should have below, 12x. Then, you add up all of your constants.(# w/ no variable). Adding negative and positive, you should get below, -11. Finally, you should of simplified your equation to 12x-11.
Equation:
7x- (x-4)= 6x -7
7x- (x-4)= 6x -7
12x
7x- (x-4)= 6x -7
