Answer:
x-3=18
Step-by-step explanation:
Answer:
x = 44/19, y = 33/20
Step-by-step explanation:
Multiply the first eq by 18, to get:
90/y - 36/x = 39
so 36/x = 90/y - 39
in this form we can plug it into the second eq:
90/y - 39 - 24/y = 1 =>
66/y = 40 =>
y = 66/40 = 33/20
Fill that in the first:
100/33 - 2/x = 13/6 =>
200/66 - 143/66 = 2/x =>
57/66 = 2/x =>
57x = 2*66
x = 132/57 = 44/19
Answer:
the length of the longer piece of cable is 24 ft
Step-by-step explanation:
shor piece = s
Long piesce = s+9
s + s+9= 39
2s = 30
s = 15
short = 15
15 +9 = 24
long = 24
15+24 = 39
Given:
The ratio of the measures of the three sides of a triangle is 
.
Its perimeter is 31.4 centimeters
To find:
The shortest side of the triangle.
Solution:
Let the measures of the three sides of a triangle are 
respectively (in cm).
Its perimeter is 31.4 centimeters.
On further simplification, we get
Divide both sides by 3.
Now, the sides of triangle are
Therefore, the length of the shortest side is 6.978 cm.
