Answer:
x = 4
Step-by-step explanation:
From the figure attached,
Two lines l and m are the parallel lines.
Angle BAD is an exterior angle of triangle ABC.
By the theorem of exterior angle of a triangle,
"Exterior angle of a triangle is equal to the sum of two opposite interior angles."
m(∠BAD) = m(∠ABC) + m(∠BCA)
28x = 16x + 48
28x - 16x = 48
12x = 48
x = 4
Therefore, x = 4 will be the answer.
Using tha appropriate triangle theorem, the value of x in the given triangle is 4
Recall the theorem ;
"The exterior angle of a triangle is equal to the sum of opposite interior angles". The opposite interior angle = 16x and 48Exterior angle = 28xExpressing as an equation :
16x + 48 = 28x
Collect like terms
16x - 28x = - 48
-12x = - 48
x = 48/12
x = 4
Therefore, the value of x is 4.

.3(3x+7)= 9x +21 help please
Answers
that is true
Step-by-step explanation:
3×3x = 9x
3×7= 21
So 9x + 21
because you cant add a variable to a number that doesnt have the same variablem
Answer:
All real numbers make this equation true, so it is true.
Step-by-step explanation:
3(3x+7)=9x+21 if I were to input 3 as x on both sides, it would equal 48 on each side.
It essentially becomes 3(9+7)=27+21
then 3(16)=48
48+48
This is true for all variables, so the equation must be true
Use your knowledge of the Triangle Sum Theory to solve for x. Then solve for ∠ L.
help plss
Answers
Answer:
X= 15
K=45
Step-by-step explanation:
The Triangle Sum Theory means that every interior angle of a triangle sums up to 180. My first approach was to put 169 as x but that isn’t correct. That is because a triangle’s smallest angles have to add up to be more than the biggest angle. Ex (10, 5, 7 that is a triangle because the sum of 5+7 is more than 10) So as you can see there are x’s next to the other numbers. That is because x needs to be able to multiply with the other numbers and stand on it’s own and add up to 180. So this would be the equation: X+8•X+3•X=180. You should find that 15 makes everything add up to 180. Now knowing x is 15 now we know that 3x is equal to 45. So k=45 That is how you solve this tricky question. Hope this helps! ❤️

solve the equation 7+2 |2x+1| =15
Answers
Answer:
I believe the answer is X=2.5
Step-by-step explanation:
7+2=9
so now we have to find what X would be so we can do the second equation
So we know that the second equation must equal 6 because 9+6=15
So now we experiment with different numbers for X
if we did 2, the new equation would be 2x2+1 which is 5, too low
if we did 3, the new equation would be 2x3+1 which is 7, too high
So we need something in the middle
in the middle of 5 and 7 is 6 which is the number we need
so to get 6 we need something in between 2 and 3, which in 2.5

where m is the slope and b the y-intercept.
3x-6y=12 Solving for y to put into the slope-intercept form
3x - 12 = 6y
y = (3/6)x - 2 Or y = (1/2)x - 2 Pt(0,-2) and (4,0) points on the line
m = (1/2) As y increases/decreases by 1, x increases/decreases by 2

x+63°+36°=180°(angle sum property in first triangle)
x+99°=180°
x=180°-99°
x=81°
x + z=180
81°+z=180°
z=180°-81°
z=99°
z+13°+y=180(angle sum property in second triangle)
99°+13°+y=180
112°+y=180°
y=180°-112°
y=68°

What does x equal in -7=-1+x/3
Answers
Hello! :)
To solve your equation, we will first simplify both sides of the equation
-7 = -1 + x/3
-7 = -1 + 1/3x
-7 = 1/3x - 1
Next, we will flip the equation
1/3x - 1 = -7
Third, we will add 1 to both sides
1/3x - 1 + 1 = -7 + 1
1/3x = -6
Last, we will Multiply both sides by 3
3 * (1/3x) = (3) * (-6)
x = -18 (ANSWER)
That means -18 is you answer

16
Step-by-step explanation:
Given that:
Number of pencils = 64
Number of erasers = 48
To obtain the GREATEST number of pencils or erasers Ms. Franco can put in each box, the we find the greatest common factor of both numbers ; 64, 48
_____64 ___48
__2__32___24

Step-by-step explanation:
Y is on a straight line. The sum of the angles on a straight line is 180.
The only other angle (that is marked) on this straight line, is a 90 degree one. So, <y + 90 = 180.
<y = 90.
Now <x + 38 = 90
so, x = 52
