Answer:
(x,y) = (2,3)
Step-by-step explanation:
y=5x-7 (i)
-3x-2y= -12
-(3x+2y)= -12
3x+2y= 12 (ii)
By putting the value of y from (i) in (ii)
3x+2(5x-7)=12
3x+10x-14=12
13x=12+14
13x= 26
x = 
x= 2
By putting the value of x in (i)
y= 5(2)-7
y= 10-7
y= 3
(x,y) = (2,3)
Answer:
38 km
Step-by-step explanation:
1. The formula to find the area of a trapezoid is 
, where a and b are the bases and h is the height.
2. To find the area, all we have to do is plug in these values and simplify!
3. (Solving)
Therefore, the area is 38 km.
Answer:
The correct answer is s³/6
Step-by-step explanation:
<u>Points to remember</u>
Volume of pyramid = (a²h)/3
Where a - side of base
h - height of pyramid
It is given that, a pyramid has a square base with sides of length s the height of The pyramid is equal to 1/2 Of the length of a side on the base
<u>To find the formula:-</u>
Here side length a = s and
height h = 1/2(s) = s/2
Volume = (a²h)/3
= (s² * s/2)/3
= s³/6
The correct answer is s³/6
