The area of a triangle is base x height/2,
so all you have to do is multiply 6x20 to get 120 and then divide that by 2 to get 60 m squared!! :)
13x - 6y = 22
x - y = 6
6(x-y) = 6*6
6x - 6y = 36
subtract both the equations
13x - 6x -6y + 6y = -14
7x = -14
x = -2
13*-2 -6y=22
-26 -6y=22
-6y = 48
y = -8
answer: x = -2
y = -8
Answer:
63/4
Step-by-step explanation:
Let the sails yard in 8 3/4 minutes= X
7 1/2 yards sails= 4 1/6 minutes
X = 8 3/4 minutes
Let us Convert the fraction to improper fraction
4 1/6 minutes= 25/6 minutes
8 3/4 minutes= 35/4 minutes
7 1/2 yards sails= 15/2 sails yard
Then
15/2 yards sails= 25/6 minutes
X = 35/4 minutes
If we cross multiply
25/6 X = 15/2 × 35/4
25/6 X =525/8
6 × 525= (25× 8)X
3150= 200X
X= 3150/200
X=63/4
