Find RS 2x+15 3x+5 6x-37
Answer:2x+15+6x-37/2=3x+5
We move all terms to the left:
2x+15+6x-37/2-(3x+5)=0
We add all the numbers together, and all the variables
8x-(3x+5)+15-37/2=0
We get rid of parentheses
8x-3x-5+15-37/2=0
We multiply all the terms by the denominator
8x*2-3x*2-37-5*2+15*2=0
We add all the numbers together, and all the variables
8x*2-3x*2-17=0
Wy multiply elements
16x-6x-17=0
We add all the numbers together, and all the variables
10x-17=0
We move all terms containing x to the left, all other terms to the right
10x=17
x=17/10
x=1+7/10
The value of RS is 31.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If RS and UT are parallel, then their corresponding sides are proportional. Thus,
RS/UT = (2x + 15)/(6x - 37)
Now,
RS/UT = (2x + 15)/(6x - 37)
Cross-multiplying.
(2x + 15)UT = RS(6x - 37)
Expanding and simplifying.
2xUT + 15UT = 6xRS - 37RS
Rearranging.
6xRS - 2xUT = 15UT + 37RS
Factorizing.
2x(3RS - UT) = 15UT + 37RS
Dividing both sides by (3RS - UT):
2x = (15UT + 37RS)/(3RS - UT)
Substituting RS = 2x + 15 and UT = 6x - 37:
2x = (15(6x - 37) + 37(2x + 15))/(3(2x + 15) - (6x - 37))
Simplifying
2x = (90x - 555 + 74x + 555)/(6x + 36)
2x = (164x)/(6x + 36)
Multiplying both sides by (6x + 36):
12x² + 72x = 164x
Simplifying
12x² - 92x = 0
Factoring out 4x.
4x(3x - 23) = 0
So,
x = 0 or x = 23/3.
Since x cannot be 0 (as it would make UT = -37, (which is not possible),
x = 23/3.
Substituting this value of x into RS = 2x + 15.
RS = 2(23/3) + 15 = 31
Thus,
The value of RS is 31.

The length of a guys wire supporting a cell tower is 120 meters. The guy wire is anchored to the ground at a distance of 80 meters from the base of the tower . To the nearest hundredth of a meter , how tall is the tower ?
Answer: 89.4427
Step-by-step explanation: I apologize if I am wrong; I used Pythagorean Thyreom, and I used the formula a=√c^2-b^2 since we are solving for side a.
a=√120^2−80^2
a=√14400−6400
a=√8000
a=89.4427
I hope this is what you are looking for :)
Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then the height of the tower is 89.44 m.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
The length of a guy's wire supporting a cell tower is 120 meters.
The guy wire is anchored to the ground at a distance of 80 meters from the base of the tower.
We know that the Pythagoras theorem.
[tex]\rm H^2 = P^2 + B^2[/tex]
We have
H = 120 m
B = 80 m
Then by the Pythagoras theorem, we have
[tex]\rm P = \sqrt{H^2 - B^2}\\\\P = \sqrt{120^2 - 80^2}\\\\P = \sqrt{14400 - 6400}\\\\P = \sqrt{8000} = 89.44[/tex]
Thus, the height of the tower is 89.44 m.

richard klein works as auto mechanic and earns the following commission rates 3.00 percent for oil changes 5.00 percent for tune ups and 6.25 percent on auto parts sales he is guaranteed a minimum salary of $2,450.00 per month last month he brought in $2,500.00 in oil changes $4,500.00 in tune ups and sold $28,200.00 in parts what is his gross pay for the month
Answer:
Richard's gross pay for the month was $ 4,512.5.
Step-by-step explanation:
Given that Richard Klein works as auto mechanic and earns the following commission rates: 3.00 percent for oil changes, 5.00 percent for tune ups and 6.25 percent on auto parts sales; and he is guaranteed a minimum salary of $ 2,450.00 per month, if last month he brought in $ 2,500.00 in oil changes, $ 4,500.00 in tune ups and sold $ 28,200.00 in parts, to determine what is his gross pay for the month the following calculation must be performed:
2,450 + (2,500 x 0.03) + (4,500 x 0.05) + (28,200 x 0.0625) = X
2,450 + 75 + 225 + 1,762.5 = X
2,450 + 2,062.5 = X
4,512.5 = X
Thus, Richard's gross pay for the month was $ 4,512.5.
Find the equation of the line shown
Answer:
y = x+1
Step-by-step explanation:
Slope-intercept form
(y = mx+b)
m = slope and b = y-intercept
The line crosses the y-axis at (0, 1), therefore the y-intercept (b) = 1
The slope (m) = 1
Because the slope is 1, it does not need to be written in the equation, as any number multiplied by 1 is that number.
