Given m∠LMN=145 what is ∠XMN?
Answer:
(4x+5)°+(6x-10)°=145°
4x+6x+5-10=145°
10x-5=145°
10x=145+5
10x=150°
x=15
(6x-10)°=(6×15-10)°
=80°
The value of ∠XMN = 80.
What is angle?An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint.
The value of total ∠LMN = 145.
∠LMN = ∠LMX +∠XMN
145 = (4x + 5) + (6x - 10)
145 = 4x + 5 + 6x - 10
145 = 10x -5
10x = 150
x = 15
Substitute the value of x in ∠XMN = (6x - 10)
∠XMN = 6×15 - 10
= 90 - 10
∠XMN = 80
Therefore, the value of the angle ∠XMN = 80.

A horse travels at about 65 kph. At this rate, how far can it travel in 20 minutes
Answer: Approximately 21.667 km
This value as a fraction is 65/3, but I think the decimal form is probably more practical in real world settings.
======================================================
Work Shown:
20 min = 1/3 of an hour, since 20/60 = 1/3. In other words, there are three chunks of 20 minutes that make up a full hour.
distance = rate*time
distance = (65 kph)*(1/3 hr)
distance = (65*1/3) km
distance = (65/3) km
distance = 21.667 km which is approximate
Answer:
Distance rate=Rate x Time
Distance= (75 km/h) 20 mins
Convert 20 mins in hours= 1/3 h
Distance= (75 km/h) (1/3 h)= 25 km.....

How are you supposed to graph #14?
Answer:
Y=mx+c
Step-by-step explanation:
The number in front of the x is the gradient. This shows how much the line goes up in the y axis for every square in the x axis. The number after the plus is the y intersect. This is where the line crosses the y axis. Start at the y intersect and draw the line. For this question, the gradient is 2, so the line goes up 2 squares on the y axis for every square on the x axis. The y intersect is 1, so it would cross the y axis at +1 on the y axis
isolated triangle 68 perimeter equal sides more than 10 ft use x for the shorter side formula
Answer:
Step-by-step explanation:
Find the perimeter of an isosceles triangle whose equal sides have a size of 10 m each and the angle between them equal to 30°. We need to know all sides in order to find the perimeter of this triangle. Let x be the base of this isosceles triangle.
Sebastian was driving down a road and after 4 hours he had traveled 98 miles. At this
speed, how many hours would it take Sebastian to thrive 245 miles?
Fill out the table of equivalent ratios until you have found the value of x.
Answer:
Let x = speed for the first 96 miles
x - 9 = speed for the last 100 miles
Distance = (rate)(time), so time = (distance)/(rate)
(time for first part of trip) + (time for last part of trip) = 4 hours
So, (96)/(x) + (100)/(x - 9) = 4
Multiply both sides by the LCD (x)(x - 9) to get
96(x - 9) + 100x = 4x(x - 9)
96x - 864 +100x = 4x2 - 36x
4x2 - 232x + 864 = 0
Divide both sides by 4 to obtain x2 - 58x +216 = 0
(x - 4)(x - 54) = 0
x = 4 or x = 54
Note that x can't equal 4 because, in that case, x - 9 would be negative, so x = 54 miles per hour.

Given f(x) = x^2 – 5x + k, and the remainder when f(x) is
divided by x - 7 is 34, then what is the value of k?
Step-by-step explanation:
f(7) = 34
7² -5(7) +k = 34
49-35+k =34
14+k = 34
k = 34-14
k = 20
