Answer:
x = 9
Step-by-step explanation:
Given
2(x + 5) = 3x + 1 ← distribute left side
2x + 10 = 3x + 1 ( subtract 2x from both sides )
10 = x + 1 ( subtract 1 from both sides )
9 = x

Answer:
If it were supposed to be a factor, 15 ( 3 + x )
Step-by-step explanation:
5 ( 13 + x )
5 x 13 = 65
5 times x = 5x
So you'd add them both,
65 + 5x

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.

the diagram shows the distance between city P and city S and city T. which measurement is closest to x, than the distance between city P and city T in miles?
Answer:
1352 miles
Step-by-step explanation:
since city t, s, and P make a right angle we can use the Pythagorean theorem to find the hypotenuse (distance from t to p) 1180 squared=1,392,400 and 660 squared =435,600 so now we add them together and take its square root which is 1352.0

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.

Answer:
x = - 3.75
y = 28.75
Step-by-step explanation:
[tex] \begin{cases} x + y = 25\\\\ 5x + y = 10 \end{cases} [/tex]
Since, x + y = 25
Therefore, y = 25 - x..... (1)
5x + y = 10......(2)
Plug y = 25 - x in equation (2), we find:
5x + 25 - x = 10
5x - x = 10 - 25
4x = - 15
x = - 15/4
x = - 3.75
Plug x = - 3.75 in equation (1), we find:
y = 25 - (- 3.75)
y = 25 + 3.75
y = 28.75
(x, y) = (-3.75, 28.75)

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.
