Answer:
12
Step-by-step explanation:
(2x-8+2x+10)/2 = 25
(4x+2) = 2×25
4x+2 = 50
4x = 50-2
4x = 48
x = 48/4
x = 12
Answer:
C. 4yd * 3ft/yd * 12in/1ft * 2.54cm/1.in = 365.76cm
Step-by-step explanation:
First you change 4 yards into feet (By multiplying the 4 yard by 3 ft/1yd)
then you convert 12 feet into inches (By multiplying the 12 feet by 12in/1ft)
after you convert 144 inches to cm (By multiplying the 144 in by 2.54 cm/1in)
you’ll have the value in cm. Which is 365.76.
Answer:
The length of the diameter of this circular area is of 30 miles.
Step-by-step explanation:
The area of a circular region can be represented by the following equation:
In which r is the radius. The diameter is twice the radius.
In this question:
So
The radius is a positive measure, so
Area in squared miles, so the radius in miles.
What is the approximate length of the diameter of this circular area
D = 2r = 2*15 = 30 miles
The length of the diameter of this circular area is of 30 miles.

Answer:
x = 12
Step-by-step explanation:
Solve for x:
(5 x)/6 + 4 = x + 2
Put each term in (5 x)/6 + 4 over the common denominator 6: (5 x)/6 + 4 = (5 x)/6 + 24/6:
(5 x)/6 + 24/6 = x + 2
(5 x)/6 + 24/6 = (5 x + 24)/6:
(5 x + 24)/6 = x + 2
Multiply both sides by 6:
(6 (5 x + 24))/6 = 6 (x + 2)
(6 (5 x + 24))/6 = 6/6×(5 x + 24) = 5 x + 24:
5 x + 24 = 6 (x + 2)
Expand out terms of the right hand side:
5 x + 24 = 6 x + 12
Subtract 6 x from both sides:
(5 x - 6 x) + 24 = (6 x - 6 x) + 12
5 x - 6 x = -x:
-x + 24 = (6 x - 6 x) + 12
6 x - 6 x = 0:
24 - x = 12
Subtract 24 from both sides:
(24 - 24) - x = 12 - 24
24 - 24 = 0:
-x = 12 - 24
12 - 24 = -12:
-x = -12
Multiply both sides of -x = -12 by -1:
(-x)/(-1) = 12
(-1)/(-1) = 1:
Answer: x = 12
