Answer:
[tex]3x - 70 = 50 + x \\ 2x = 120 \\ x = 60[/tex]
so ..
X=60
and
3x-70=180-60=110
Step-by-step explanation:
According to the theorem of exterior Angle,Measure of Exterior angle=Sum of two OPPOSITE interior anglesAnswer:
angle LKM = 110 degrees
Step-by-step explanation:
angle JKL = 180 - (3x-70) because they are supplementary angles
angle JKL + x + 50 = 180 degrees because the sum of all the interior angles of a triangle equals 180 degrees
substituting for angle JKL:
180 - (3x - 70) + x + 50 = 180
180 - 3x +70 + x + 50 = 180
simplify:
-2x = -120
x = 60 degrees
angle LKM = 3(60)-70 = 110 degrees

Find the missing side length.
Assume that all intersecting sides meet at right angles.
Be sure to include the correct unit in your answer.
Answer:
the answer is 12 yd if you are talking about the question mark.
Step-by-step explanation:
Well, if you split this figure into two rectangles, then the 16 yd length becomes 12 yd because the one congruent to it is 4 yd. Both sides are congruent so you'd get 12 yd.

Sadiq measured the dimensions of a 1 kg bag of sugar and found the length was 9.2 cm, the width was 6 cm and the height was 14.1 cm.
Calculate the density of the sugar in g/cm3
Answer:
[tex]d=1.28\times 10^{-6}\ g/cm^3[/tex]
Step-by-step explanation:
The mass of a bag of sugar, m = 1 kg = 0.001 g
Length of bag, l = 9.2 cm
Width of bag, b = 6 cm
Height of the bag, h = 14.1 cm
We need to find the density of the sugar bag.
Density = mass/volume
So,
[tex]d=\dfrac{0.001\ g}{9.2\times 6\times 14.1\ cm^3}\\\\d=1.28\times 10^{-6}\ g/cm^3[/tex]
So, the density of the bag is [tex]1.28\times 10^{-6}\ g/cm^3[/tex].
A factory can build 15 cars every hour. If at a certain time of day , they have already built 9 cars,how many cars in total will they have built 5 hours from now?
Answer:
They would have built 84 cars
Step-by-step explanation:
From the question, they have already built 9 cars
Now, the hourly production rate is 15 cars per hour;
So therefore, in 5 hours, total that would have been built excluding the initial 9 will be;
15 * 5 = 75 cars
Now, let us add the initial 9
we have this as 9 + 75 = 84 cars
i have i need to use the substitution method to work out what x and y is
5y−2x=10
8x+5y=60
Answer:
pick the simplest of the 2 equations
Step-by-step explanation:
5y-2x=10
5y = 2x +10
y = 2/5x + 2
now substitute
8x + 5(2/5X +2)=60
8x + 2x + 10 = 60
10x = 50
x = 5
y = 4

Consider this system of equations.
f(x)=x−4g(x)=−x−2
Plot the point that represents the solution to the equation f(x)=g(x).
We are given two functions.
[tex]f(x)=x-4\\g(x)=-x-2[/tex]
The point that represents the equation [tex]f(x)=g(x)[/tex], will also be the intersection of those two lines, meaning we can set the two equations equal to each other and solve for [tex]x[/tex].
[tex]f(x)=g(x)\\x-4=-x-2\\2x=2\\x=1[/tex]
Now that we are given the x value, we can plug this value back into either equation and solve for the y value.
[tex]f(1)=1-4\\f(1)=-3[/tex]
The point of intersection will be [tex](1,-3)[/tex].

two times the sum of a number and 18 is at least -21
Answer:
2x + 18 ≥ 21
x ≥ 2/3
Step-by-step explanation:
Let sum be X
2 times the sum means 2x
the sum of a number and 18 means x + 18
at least -21 means ≥ 21
put them together, and you get, 2x + 18 ≥ 21
If solving for x,
2x + 18 ≥ 21
2x ≥ 3
x ≥ 2/3

A metal bar has a mass of 960g and a volume of 120cm³. Find the density of the metal in the bar.
Answer:
Density = 8g/cm³
Step-by-step explanation:
Density = Mass/Volume
Given the following
Mass = 960g
Volume = 120cm^3
Substitute
Density = 960g/120cm^3
Density = 8g/cm³
A red-light flashes every 28 seconds. A green light flashes every 24
seconds. They both flash at the same time. After how many seconds will
they both next flash at the same time
Answer:
168 seconds
I edited the answer.
Step-by-step explanation:
To find the the time taken for both lights to flash at the same time, we need to find the lowest common multiple of 28 and 24.
28 x 6 = 168, 24 x 7 = 168
The LCM of 28 and 24 is 168.
So it takes 168 seconds for both lights to flash at the same time.
Both lights will flash together again at 2 minutes and 8 seconds.
To find When will they flash together again if they flash together.
What is LCM?LCM is the method to find the smallest possible multiple of two or more numbers.
Given that,
A red light flashes once every 28 seconds
A green light flashes once every 24 seconds
A red light flashes every 28 seconds and green light flashes once every 32 seconds. Therefore, we have to find their least common factor.
LCM(28 , 24) = 168
The red and green light will flash together after every 168 seconds.
Time =168 seconds
Time =168 / 60 minutes
Time = 2 minutes and 8 seconds
The red and green light will flash together after every 2 minutes and 8 seconds.
Hence, both lights will flash together again at 2 minutes and 8 seconds.

Given:
A figure of a circle. A secant and tangent of the given circle.
To find:
The correct equation.
Solution:
According the intersecting tangent secant theorem, the square of tangent is equal to the property of external segment of secant and the measure of the secant.
Using intersecting tangent secant theorem, we get
[tex]6^2=x(x+5)[/tex]
It can be written as
[tex]x(x+5)=6^2[/tex]
The required equation is [tex]x(x+5)=6^2[/tex].

In triangle ABC below , which is the longest side?
Answer:
the longest side is AC
Step-by-step explanation:
The longest side will be opposite the largest angle.
4x+(2x-6) + (4x-4) = 180 (all triangle interior angles add up to 180 degrees)
simplify:
10x - 10 = 180
10x = 190
c= 19
angle B = 4(19) = 76 degrees
angle A = 2(19) - 6 = 32 degrees
angle C = 4(19) - 4 = 72 degrees
so the longest side is AC
