Answer:
Step-by-step explanation:
J and K are equal
8x - 23 = 6x + 11 Add 23 to both sides
8x = 6x + 11 + 23 Combine the right
8x = 6x + 34 Subtract 6x from both sides
8x - 6x = 34 Combine the left
2x = 34 Divide by 2
x = 34/2
x = 17
=================================
M and L are both supplementary to J and K respectively.
J = 8x - 23
J = 8*17 - 23
J = 136-23
J = 113
K = 113
===================================
M + 113 = 180
M = 180 - 113
M = 67
L = 67
Answer:
Let the breadth is x, then the length is 3x.
<u>The area is:</u>
<u>The breadth is decreased by 2 m: </u>
<u>The length is increased by 4m: </u>
<u>The area is now:</u>
- (x - 2)(3x + 4) = 3x² - 1/3(3x²)
- 3x² + 4x - 6x - 8 = 2x²
- x² - 2x - 8 = 0
- x² - 2x + 1 = 9
- (x - 1)² = 3²
- x - 1 = 3
- x = 4
The breadth was 4 m and the length 12 m
Answer:
Width is 120ft but may be different if the "times the width" information is given. Follow the same process.
Step-by-step explanation:
To solve the problem, write an expression that relates length and width using the information given to you. "The length of a rectangular park is 3 feet shorter than times its width" means that l = 3 + w. Since no number is given for "times its width" we disregard this portion. If you have the information then you would include it here l = 3 + _w.
So using the expression l = 3 + w, substitute l = 123. Then the width will be:
l = 3 + w
123 = 3 + w
120 = w
Answer:
km per min
Step-by-step explanation:
6km ÷ 60 = 0.1
Bonolo ran 0.1 km per min
it takes 100 mins= 0.1×10
100 mins means 1 hour 40 min
