we know that
A
right triangle has two equal legs
Let
x-----> the length side of the leg of the triangle

Answer:
(5/6)
Step-by-step explanation:
Bc (2/3)=0.666666666667....
(2/15)*(4/5) doesn't make 0.666666666667
(4/5)*(5/6)= 0.666666666667
Answer:
x= 200
Step-by-step explanation:
The given equation is:
1/5 x - 2/3 y = 30
The value of y is 15
Put the value of y in the given equation:
1/5 x - 2/3(15) = 30
1/5 x- 10 = 30
Take the L.C.M of the denominator
x-50/5 = 30
Move the denominator to the R.H.S
x-50 = 30*5
x-50 = 150
Combine the like terms
x= 150+50
x = 200
The value of x is 200...
Answer:
10
Step-by-step explanation:
first u take 2 1/2 and change it into a improper fraction.
so 2 X 2 = 4 then + 1
=5
5/2 divide by 1/4
which is 10
3*2=6
2 2/3
7*2=14
