Answer:
w = 10
Step-by-step explanation:
Solve for w:
w/4 + 8.25 = 10.75
Put each term in w/4 + 8.25 over the common denominator 4: w/4 + 8.25 = w/4 + 33/4:
w/4 + 33/4 = 10.75
w/4 + 33/4 = (w + 33)/4:
(w + 33)/4 = 10.75
Multiply both sides of (w + 33)/4 = 10.75 by 4:
(4 (w + 33))/4 = 4×10.75
(4 (w + 33))/4 = 4/4×(w + 33) = w + 33:
w + 33 = 4×10.75
4×10.75 = 43:
w + 33 = 43
Subtract 33 from both sides:
w + (33 - 33) = 43 - 33
33 - 33 = 0:
w = 43 - 33
43 - 33 = 10:
Answer: w = 10
Answer:
Step-by-step explanation:
Let "x" be the number.
Product of 6 and x (6*x), increased by 4 =
Product of 12 and x, (12*x), decreased by 20 = .
Set both expressions equal to each other and solve for x as shown below:
(equation)
Subtract 12 from both sides
Subtract 4 from both sides
Divide both sides by -6
Answer:
<em> 108 degrees</em>
Step-by-step explanation:
From the diagram we are given
Interior angles are 2x + 1 and 63 degrees
Exterior angle = 5x -2
The sum of interior angles is equal to the exterior angle
2x + 1 + 63 = 5x - 2
2x + 64 = 5x - 2
2x - 5x = -2-64
-3x = -66
x = -66/-3
x = 22
Get the exterior angle:
Exterior angle = 5x-2
Exterior angle = 5(22) - 2
Exterior angle = 110-2
Exterior angle = 108 degrees
<em>Hence the measure of the exterior angle is 108 degrees</em>
The value of x is 8 and it is right
