Solve for x.
23=79(6x−36)+9
Answers
23=474x-2835
-474x=-2835-23
-474x=-2858
x=1429/237
23 = 79(6x - 36) + 9
Distribute 79 inside the parentheses.
23 = 474x - 2,844 + 9
Combine like terms.
23 = 474x - 2,835
Add 2,835 to both sides.
2,858 = 474x
Divide both sides by 474.
x = 2,858/474
Simplified by dividing both sides by 2: 1,429/237
Your answer is x = 1,429/237.

Answer:
x = 86
Step-by-step explanation:
note: a straight line is regarded to have an angle of 180 degrees.
in this case CUW is a straight line
I shall show you two methods . which ever one you choose will still get the same answer. however understanding both will help you use them for other questions
method 1
therefore in order to solve the value of x we need to get the missing angle in the triangle first which is angle WUV
Angle WUV
notes : a triangle has a total angle of 180 degrees
hence we can create an equation to get the angle WUV
lets make the missing angle as Y , this will help to find the answer.
46 + Y + 40 = 180
now make Y the subject of formula
Y = 180 - 40 - 46
Y = 94
now in order to find x .
since the CUW is a straight line with 180 degrees
hence x = 180 - 94 = 86
x = 86
method 2
since the triangles total angle is 180 degrees and also the straight line is also 180 degrees. we can just add the total of the 2 sides of the triangle ( the two interior angles can be added together to get the value of the exterior one)
40 + 46 = 86
x = 86
Two interior angles is equal to one exterior angle

Answer:
1) 5
2) 5
Step-by-step explanation:
Data provided in the question:
(3²⁷)(5¹⁰)(z) = (5⁸)(9¹⁴)()
Now,
on simplifying the above equation
⇒ (3²⁷)(5¹⁰)(z) = (5⁸)((3²)¹⁴)()
or
⇒ (3²⁷)(5¹⁰)(z) = (5⁸)(3²⁸)()
or
⇒
or
⇒
or
⇒
we can say
x = 5, y = 2 and, z = 3
Now,
(1) y is prime
since, 2 is a prime number,
we can have
x = 5
2) x is prime
since 5 is also a prime number
therefore,
x = 5
