Step-by-step explanation:
Let us consider the length of a line segment to be 'x'
Let the other line segment be 'y'
One line segment is 12 less than twice the length of other segment.
X = 2y - 12
The sum of both the lengths = 69cm
X + Y = 69
X = 69 - Y
Substitute the X value in the first equation
X = 2y - 12
69 - Y = 2Y - 12
- Y - 2Y = -12 -69
- 3Y = - 81
3Y = 81
Y = 81/3
Y = 27 CM
Length of One of the line segment is 27cm
The length of the other line segment 'x'
is
X= 2y - 12
X = 2(27) - 12
X = 54 - 12
X = 42cm
The length of the line segments are 42cm and 27cm.
Answer:
See below
Step-by-step explanation:
Well, we know the scale is 1 1/2 inches to 4 feet and that one side length of the scaled drawing sqaure is 3 inches, so . . .
3/1 1/2 (3 divided by one and one-half)
to get: 2
Then multiply it by the scale factor of 4
2*4= 8
But remeber, this is only ONE side of the garden, so multiply this by 4
8*4=32
Next we want to see the number of links it takes to build the garden
Since one link measures 2 2/3 feet you have to divide
32/ 2 2/3 (32 divided by two and two-thirds)
to get an answer of : 12 links
Answer:
v = 1
u = 2
Step-by-step explanation:
Given is a special right triangle with angle measures as follows:
90-60-30
The side lengths would be :
2x- x-x
in the image it shows that the second side length (the one that sees angle measure 60) is from this we can conclude x = 1 so:
v = 1 and
u = 2
Ok,
divide by 2 on both sides...
So X = 3/8!
