Solve for x:
7x + 5 + x - 3 + x = 5
Answer:
x=1/3
Step-by-step explanation:
9x+5-3=5
9x=3
x=1/3
Answer:
x=1/3
Step-by-step explanation:
7x + 5 + x - 3 + x = 5
-5 -5 (rewrite)
7x + x - 3 + x = 0
7x + x + x = 9x (collect like terms) (rewrite)
9x - 3 = 0
9x = 3
(divide both sides by 9)
x= 1/3

See below
Step-by-step explanation:
A > [tex]Sin^{2} x + cos^{2} x = 1 \\[/tex]
Divide both side by sin^2 x , and we get
[tex]\frac{sin^2 x}{sin^2 x} + \frac{cos^2 x}{ sin^2 x} = \frac{1}{sin^2 x}[/tex]
[tex]1+ cot^2 x= cosec^2 x[/tex]
Subtracting cosec^2 x from both sides we get
[tex]Cosec^2 x - cot^2 x = 1[/tex]
B>lets break tan θ into its components tan θ = sin θ / cos θ and cot θ = 1/ tan θ
Tan θ + cot θ= Sin θ/cos θ + cos θ/ sin θ = sin^2 θ + cos^2 θ / sin θ cos θ= 1/ sin θ cos θ = sec θ cosec θ
Answer:
Step-by-step explanation:

Look at the picture of a scaffold used to support construction workers. The height of the scaffold can be changed by adjusting two slanting rods, one of which, labeled PR, is shown:
A support structure is shown in which a right triangle PQR is formed with the right angle at Q.
Part A: What is the approximate length of rod PR? Round your answer to the nearest hundredth. Explain how you found your answer, stating the theorem you used. Show all your work. (5 points)
Part B: The length of rod PR is adjusted to 17 feet. If width PQ remains the same, what is the approximate new height QR of the scaffold? Round your answer to the nearest hundredth. Show all your work. (5 points)
Answer:
Part A: 2 * sqrt(65) ft, or about 16.12451549... ft
Part B: sqrt(93) ft, or about 9.64365076... ft
Step-by-step explanation:
Part A: A right triangle is formed, so we can use the Pythagoren theorem to solve for the length of rod PR. The Pythagoren theorem is a^2 + b^2 = c^2, with PR being c^2, and PQ and QR being a^2 and b^2 (interchangeably). So, we plug in the lengths and get the equation 14^2 + 8^2 = c^2. This is equal to 144 + 64 = c^2. Simplified, we have 208 = c^2. Getting the square root of both sides, we find that c is equal to approximately 16.12451549... feet.
Part B: Now we are solving for a side length rather than the hypotenuse. We can use the Pythagorean theorem here too. We have: a^2 + 14^2 = 17^2. We solve and get a^2 + 144 = 289. Simplified, a^2 = 145. The square root of 145 is approximately 9.64365076... feet, our answer.

A store has a 20% off discount. If the original price of a shirt is $48, how
much will you pay?
Answer:$38.70
Step-by-step explanation:

A soccer field measures 90 meters wide by 120 meters long starting together in one corner you walk the diagonal to the opposite corner while your friend walks the length and with to get the same corner how much further dose your friend walk
Answer:
The friend walks 60 m further than the other person
Step-by-step explanation:
Given the dimensions of the soccer field:
Width = 90 m
Length = 120 m
One person walks along its diagonal.
As the length and width of the field are perpendicular, Diagonal can be calculated using Pythagorean Theorem:
[tex]Diagonal ^2 =Length^2+Width^2[/tex]
[tex]Diagonal ^2 =90^2+120^2\\\Rightarrow Diagonal ^2 =8100+14400\\\Rightarrow Diagonal ^2 =22500\\\Rightarrow Diagonal =150\ m[/tex]
So, the distance walked by the person along the diagonal = 150 m
Distance walked by the person's friend to reach the opposite point = Width + Length = 120 + 90 = 210 m
So, the difference of the two distances will give us the distance that was walked further by the friend.
The difference is = 150 - 90 = 60 m
So, the friend walks 60 m further than the other person.

Answer:
3 pigs
Step-by-step explanation:
First split the shape into two rectangles to find the area. On the left you can make the rectangle 10*7 and on the right subtract 7 from 16 to get 9 so the one on the right is 9*6. Find the area of both rectangles by multiplying, which will get you 70 and 54 respectively. Add these to get 124 square meters of space in the field. Now you will have to divide it by 36 to see how many pigs can fit, which results in the answer 3.4444... Round down to get 3 pigs as you can not fit another pig in the .4444... of space.
Consider the original trapezoid and the reduction. 13.5 cm 3 cm 3 cm 9 cm А 16.5 cm 11 cm Figures not drawn to scale. What is the length of side A, in centimeters, on the reduced trapezoid? 1 O 1.5 2 4.5
Answer:
c
Step-by-step explanation:
The length of side A in the new trapezoid after reduction is: C. 2 cm.
What is a Reduction?A reduction is a transformation which reduces the size of an original figure, in such a way that the ratios of the corresponding sides of the original and new figure are equal.
Based on the definition of reduction, the following ratio can be written:
16.5/11 = 3/A
Cross multiply
A = (11 × 3)/16.5
A = 2 cm.
Therefore, the length of side A in the new trapezoid after reduction is: C. 2 cm.

What is the equation of the line in slope-intercept form?
Answer:
y=3/5x+3
Step-by-step explanation:
The first blank is the slope. To find the slope, you first get 2 points on the graph. I chose (-5,0) and (0,3). You then find the difference in the Y values, which is positive 3, and find the difference in the X values, which is 5. Slope is y/x, so the slope would be 3/5. The second blank is the y-intercept, which is where the line meets the y value with an x value of 0. The y-intercept would be 3.
