Solve the proportional
equation below:
10/4=x+8/x-1
PLS HELP AND EXPLAIN HOW U GOT THE ANSWER
Answer:
x = 7
Step-by-step explanation:
10 / 4 = x + 8 / x - 1
[cross multiply]
10 (x - 1) = 4 (x + 8)
[distribute the factors]
10x - 10 = 4x + 32
+ 10 + 10
[add 10 to both sides to cancel out -10]
10x = 4x + 42
-4x -4x
[subtract both sides by 4x to cancel out 4x]
6x = 42
÷6 ÷6
[divide both sides by 6 to simplify 6x to x]
x = 7
________
x = 7 → 10 / 4 = x + 8 / x - 1 →
(7) + 8 / (7) - 1 → 15 / 6 →
15 ÷ 3 / 6 ÷ 3 → 5 / 2 →
5 × 2 / 2 × 2 → 10 / 4 = 10 / 4
A new cell tower is being constructed and needs a guy-wire connected 180 feet up the tower and it needs to make an angle of 52° with the ground. What length does the wire need to be?
Answer:
228.42 ft
Step-by-step explanation:
To solve for this question, we would be applying the Trigonometric function of Sine.
Sin theta = Opposite/Hypotenuse
Theta = 52°
Opposite = 180ft
Hypotenuse = Length of the wire = x
Hence:
sin 52 = 180/x
x = 180/sin 52
x = 228.42327871 ft
Approximately = 228.42 ft
Angel and Jayden were at track practice. The track is 2/5 kilometers around. Angel ran 1 lap in 2 minutes. Jayden ran 3 laps in 5 minutes. How far does Jayden run in one minute?
Answer:
6/25 km in 1 min; or 0.24 km/min
Step-by-step explanation:
The info about Angel is not necessary.
Jayden runs 3 laps in 5 mins
Each lap is 2/5 km, so Jayden runs 3 x (2/5 km) in 5 min = 6/5 km in 5 min.
Distance = rate x time
6/5 km = rate (5 min)
We want to isolate r (rate), so divide both sides by 5 min
6/5 km ÷ 5 min = r
6/5 km (1/5 min) = r
6/25 km/min = r (notice how the units worked out correctly to km/min)
So, Jayden runs 6/25 km in 1 min.
Answer:
6/25 miles km in a minute

Y=x. Given A(7,-4), B(6,4), and C(-1,-5), what are the coordinates of the vertices of A’B’C for the reflection
Answer:
The coordinates of the vertices of A'B'C' is:
A'(-4, 7)B'(4, 6)C'(-5, -1)Step-by-step explanation:
Given the coordinates of the triangle
A(7,-4)B(6,4)C(-1,-5)Reflection in the line y=x
We know that the rule of reflection in the line is y = x is:
(x, y) → (y, x)
Thus,
The coordinates of the vertices of A'B'C' for the reflection in the y = x
(x, y) → (y, x)
A(7, -4) → A'(-4, 7)
B(6, 4) → B'(4, 6)
C(-1, -5) → C'(-5, -1)
Thus, the coordinates of the vertices of A'B'C' is:

Answer:
Option D The pattern is multiplicative because the earnings are 12 times the number of hours worked in each pair of values is correct option.
Step-by-step explanation:
At x-axis we have number of hours worked and y-axis represents earnings in dollars.
We can make the table:
Number of hours worked (x) earnings in dollars (y)
1 12
2 24
3 36
4 48
5 60
Now, we need to find the pattern.
If we add 1+ 11 we get 12, but if we add 2+ 11 we get 13 and not 24 so, the pattern is not additive.
Now, if we multiply 1 by 12 (1 x 12) we get 12,
then 2 x 12 = 24
3 x 12 = 36
4 x 12 = 48
and 5 x 12 = 60
The same number if multiplied with x-axis we get y-axis.
So, the pattern is multiplicative. and we are multiplying 12 with the number of hours worked, so the correct option is option D.
Option D The pattern is multiplicative because the earnings are 12 times the number of hours worked in each pair of values is correct option.

A lawyer has an annual income of $154,120. The income tax the lawyer has to pay is 6%. What is the amount of income tax in dollars and cents that the lawyer has to pay
Answer:
$9,247.20
924,720 cents
Step-by-step explanation:
The computation of the amount of the income tax is shown below:
In dollars
= Annual income × rate of income tax
= $154,120 × 6%
= $9,247.20
Now in cents, it would be
= Annual income × rate of income tax × 100
= $154,120 × 6% × 100
= 924,720 cents

The diagram is not drawn to scale.
X = 1
Answer:
x = 33
Step-by-step explanation:
Sum of the interior angles of a 5-sided polygon = 540°
Therefore all the interior angles of the given polygon would all be equal to 540°.
Thus:
(4x - 25)° + (3x + 25)° + (2x - 3)° + (4x)° + (3x + 15)° = 540°
Solve for x
4x - 25 + 3x + 25 + 2x - 3 + 4x + 3x + 15 = 540
Combine like terms
4x + 3x + 2x + 4x + 3x - 25 + 25 - 3 + 15 = 540
16x + 12 = 540
16x = 540 - 12
16x = 528
Divide both sides by 16
x = 33
Which costs the most per ounce, 60 oz. of peanut butter for $5.40, 28 oz. for $2.24, or 16 oz. for $1.76? Explain how you got your answer.
Answer:
28 oz. for $2.24 cost most per ounce
$12.5 per oz
Step-by-step explanation:
Find the cost per ounce by dividing the total oz by cost of the total oz
60 oz. of peanut butter for $5.40
Cost per the ounce = 60 oz / $5.40
= $11.11 per oz
28 oz. for $2.24
Cost of peanut butter per ounce = 28 oz / $2.24
= $12.5 per oz
16 oz. for $1.76?
Cost of peanut butter per ounce = 16 oz / $1.76
= $9.10 per oz
28 oz. for $2.24 cost most per ounce
