Answer:
x = 13 1/2 days
Step-by-step explanation:
1/2 acre 2 1/4 acre
------------ = -------------------------
3 days x days
using cross products
1/2 * x = 2 1/4 * 3
change 2 1/4 to an improper fraction (4*2+1)/4 =9/4
1/2 x = 9/4*3
1/2x = 27/4
multiply each side by 2
2 * 1/2 x = 27/4 * 2
x = 27/2
change back to a mixed number
x = 13 1/2
Answer:
z=16
Step-by-step explanation:
z/4-2=2(take l.c.m)
or,(z-8)/4=2
or,z-8=8
z=16
If you observe the two given equations, the left hand side of both equation is the same and is equal to y.
Since the left hand side of two equations is the same, we can conclude that the right hand side of two equations must also be the same.
So, setting them right hand sides of both equations equal to each other and solving for x, we can find the solution to the simultaneous equations.
Therefore, the correct answer is option B
Answer:
13
Step-by-step explanation:
Diagonals of a rhombus are perpendicular bisector.
Hence, triangle ABE so formed would be a right triangle right angled at E.
Therefore, by Pythagoras theorem:
Alright,
-9/10x + y = 1 1/10
