Answer:
x = 10
Step-by-step explanation:
1. First, we should recognize that 6x and 5x + 10 are corresponding angles, meaning they occupy the same relative position. They're also congruent.
This means that 6x = 5x + 102. (Solving)
Step 1: Subtract 5x from both sides.
[tex]6x - 5x = 5x + 10 - 5x[/tex] [tex]x = 10[/tex]Step 2: Check if solution is correct.
[tex]6(10)=5(10)+10[/tex] [tex]60 = 50 + 10[/tex] [tex]60 = 60[/tex]Therefore, x = 10.

Answer:
Star and square
Step-by-step explanation:
Answer: B
Step-by-step explanation:
The origin is the center of the 2 bold lines. As you can see, the square is 1 unit right and then 2 units up. The star is 2 units left and 1 unit up. And the triangle is 2 units down and 2 units left.
square: 1 then 2
star: 2 then 1
triangle: 2 then 2.
From this you can see that the square and the star are the same distance from the origin.
So the answer is B.

roy gets 10% extra time in school exams. If Roy gets 1 hour 33 minutes and 30 seconds to complete his maths exam, how long do most students get.
Answer:
1 Hour 25 Minutes
The time that most of the students get is 1 hour and 25 minutes, computed using fractions and percentages.
What are fractions?Fractions are a relational representation of certain parts of a quantity, to the total parts of that quantity.
Written as a/b, read as "a by b", functions as a divided by b, represents a fraction a over b, where a is the numerator and b is the denominator.
What are percentages?Percentages are a fractional representation of a quantity, where the whole quantity is fixed to be 100.
Fractions are converted to percentages by multiplying them by 100, while percentages are converted to fractions by dividing them by 100.
How to solve the question?In the question, we are informed that Roy gets 10% extra time in school exams.
We are asked for the time that is given to most of the students if Roy gets 1 hour 33 minutes and 30 seconds.
For standardization, we work in seconds.
We assume the required time to be x seconds.
Time given to Roy:
30 seconds implies 30 seconds,
33 minutes implies 33*60 = 1980 seconds,
1 hour implies 1*60*60 = 3600 seconds.
Thus, the total time given to Roy = 30 + 1980 + 3600 = 5610 seconds.
We are informed that Roy gets 10% extra time in school exams.
Thus, the time given to Roy = Normal time + 10% of normal time,
or, 5610 = x + 10% of x,
or, 5610 = x + 10/100 of x {percentages are converted to fractions by dividing them by 100},
or, 5610 = x + x/10,
or, 5610 = 11x/10,
or, x = 5610*10/11 = 5100.
Thus, the time given to most of the students = 5100 seconds = 5100/60 minutes = 85 minutes = 1 hour and 25 minutes.
Thus, the time that most of the students get is 1 hour and 25 minutes, computed using fractions and percentages.

a) What is the x-intercept?
b) What is the y-intercept?
c) What is the slope?
Please help ASAP
Answer:
Step-by-step explanation:
The x-intercept is where y is 0.
The y-intercept is where x is 0.

Directions: Solve for x, then find each angle measure.
The sum of all three interior angles of a triangle is 180° thus the measure of x for the given triangle is 8 therefore,∠E = 75°,∠D = 38°, and ∠F = 67°.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
It is known that the sum of all three angles inside a triangle will be 180°.
Therefore, ∠E + ∠F + ∠D = 180°.
Given that, ∠E = 9x + 3,∠F = 11x -21 and ∠D = 5x - 2
So, 9x + 3 + 11x - 21 + 5x - 2 = 180
25x - 20 =180
25x = 200
x = 8
So,
∠E = 9(8) + 3 = 75°
∠F = 11(8) - 21 = 67°
∠D = 5(8) -2 = 38°
Hence "The sum of all three interior angles of a triangle is 180° thus the measure of x for the given triangle is 8 therefore,∠E = 75°,∠D = 38°, and ∠F = 67°".
