Answer:
x=3, x=[tex]-\frac{5}{2}[/tex]
Step-by-step explanation:
2x^2-x-15=0
2 times -15 equals -30, so plug in 5x and -6x for -x
2x^2-6x+5x-15 factor,
2x(x-3) 5(x-3)
x-3=0 2x-5=0
x=3 x= -5/2
In the figure shown below, if line m is parallel to line n, then find the value of x
Answer:
Step-by-step explanation:
The two angles shown are considered "alternate interior angles" because they lie on the INSIDE of two parallel lines, but on alternate/opposite sides of the transversal line. Alternate interior angles are congruent. You can use transformations to see that they are congruent. Therefore, you should set the two expressions equal to each other and solve for x.
The value of x is 25.
Given,
Line m is parallel to line n
The figure has two alternate interior angles.
- (2x - 10)°
- (65 - x)°
We need to find x.
What does Alternate Angles Theorem says?It states that when two parallel lines are cut by a transversal the resulting alternate interior angles or alternate exterior angles are congruent.
We have ,
From the figure:
Two alternate interior angles.
- (2x - 10)°
- (65 - x)°
Since line m and line n are parallel and from the alternate angles theorem
we see that,
2x - 10 = 65 - x
2x + x = 65 + 10
3x = 75
x = 75/3
x = 25
Thus the value of x is 25.

Let x = the length of the shorter piece of rope. x + (1/2)x = 24 (3/2)x = 24 (2/3)(3/2)x = (2/3)(24) x = 16 The lengths of rope are 16 feet and 8 feet. A student solves the problem to the left as shown. Which statements describe the solution? Check all of the boxes that apply.
Answer:
Step-by-step explanation:
Given the question
A rope is 24 feet long. It is cut into two pieces such that one piece is half the length of the other. Find the lengths of the two pieces of rope.
Options
The stated solution is correct (lengths of 16 feet and 8 feet).
Based on the way the variable is defined, the equation should be x + 2x = 24.
The equation is written correctly, but there is an error in solving the equation.
The way the variable is defined, and because x=16, the longer piece of rope would be 32 feet, which is not possible.
2
Let the length of one piece be x (shorter piece) and the other be y.
If the rope is cut into two pieces and 24ft long, then;
x+y = 24.......... 1
If one piece is half the length of the other, then x = y/2..... 2
substitute equation 2 into 1
y/2 + y = 24
take the LCM
y+2y/2 = 24
3y/2 = 24
cross multiply
3y = 48
Divide both sides by 3;
3y/3 = 48/3
y = 16 feet
Since x = y/2
x = 16/2
x = 8 feet
Based on the calculation above, I can conclude that;
- The student stated solution is correct (lengths of 16 feet and 8 feet)
- The way the variable is defined, and because x=16, the longer piece of rope would be 32 feet, which is not possible.
- Based on the way the variable is defined, the equation should be x + 2x = 24.

Carolyn and her basketball team are traveling form Oak City to the beach for the championships. The distance to the beach is about 1,344 miles. The team plans to drive 50 miles per hour. About how many hours will it take for Carolyn and her team to get to the beach?
Answer:
It will take 26.88hours to get to the beach
Step-by-step explanation:
From the problem statement, we are asked to find the time required to reach the beach.
given data
distance s=1344 miles
speed v= 50 mph
time t=?
we know that the relationship between speed, distance and time is given as
velocity=distance/time
substituting our given data into the expression we have
50=1344/t
making t subject of the formula we have
t=1344/50
t= 26.88 hours
Therefore it will take 26.88hours to get to the beach

A leatherback sea turtles was swimming at 850 below sea level. He went 165 meters and then descendes 165 meters. Draw a number line to show the change in position of the sea turtles from depth it was swimming. What integer represents the sea turtles change in position?
Answer:
The answer is below
Step-by-step explanation:
a) Let negative means the turtle position when descending and positive for going up. Therefore since the turtle was 850 meters below see level, it was at -850. It then moves 165 meters up, hence its new position is -685 meters (-850 + 165). Lastly it moves down 165 meters, hence its new position is -850 meters (-685 - 165)
b) The change in position is the sum of the movements = +165 - 165 = 0 meters.

Answer:
The x intercepts are (-5, 0) and (2, 0)
The y intercept is (0, -10).
Step-by-step explanation:
The x intercepts are (-5, 0) and (2, 0)
When you set the numbers x + 5 and x - 2 equal to zero, you solve for x and that becomes the x-intercept.
The y intercept is (0, -10).
When you multiply the numbers, you result in [tex]x^{2} +3x - 10[/tex].
Then, set the x values to 0 and evaluate. That leaves you with -10, which is the y-intercept.

5 less than a number is equivalent to 1 more than three times the number. the number is
Answer:
x = -1
Step-by-step explanation:
5 less than a number is equivalent to 1 more than three times the number
number = x
x - 5 = 3x + 1
now im going to get the numbers and variable on different sides
x - 5 + 5 = x
3x + 1 - 3x = 1
x + 3x = 4x
1 - 5 = -4
4x = -4
lastly im going to divide each side by 4
4x / 4 = x
-4 / 4 = -1
x = -1
Harvey flew south 300 miles. He changed planes and then flew east 500 miles. If he travels a straight path back home, how many miles will he fly? Round to the nearest mile.
Answer:
583 miles
Step-by-step explanation:
Let's draw this out (see attachment).
The straight line path creates the hypotenuse of a right triangle with legs of lengths 300 and 500. So, we use the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:
a² + b² = c²
Here, a = 300 and b = 500. Then:
300² + 500² = c²
90000 + 250000 = c²
340000 = c²
c = √340000 ≈ 583.1 ≈ 583 mi
Thus, the answer is 583 miles.

42.5 i think
The whole angle is 127 minus the angle we know (32) this leaves us with 85 for the rest of the angle but we still have to deal with the angle bisector so we divide it by 2 leaving us with 42.5 I'm pretty sure.

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. Explain in words each step to find the following question:
At what number(s) measures played would the sound level be at 80 decibels?
Answer:qsq
Step-by-step explanation:
Answer:
Step-by-step explanation:
The answer to this is 1 or 7:
To find the range for the number of measures played to satisfy our solution, we must solve for x using s = 80.
Next, we subtract 50 from both sides of the equation.
Next, we divide both sides of the equation by 10
Next, to eliminate the absolute value bars, we will add a ± sign in front of our s value, 3.
Finally, we add 4 to both sides of our equation giving us 4 ± 3 = x
Separating this into two equations, we get 4 - 3 = x and 4 + 3 = x
Therefore, x, the number of measures of music played, must be either 1 or 7.
