Step-by-step explanation:
3x+2y=22
5x-2y=42
by adding both equation
8x. =64
x=64/8=8
substituting x in the 1st equation
we get,
3*8+2y=22
24+2y=22
2y=22-24
y=-2/2=-1
therefore,
x=8
y=-1
The area of the spinning board is divided into 10 equal sections.
Probability in this case will be = Area of favorable outcome/Total Area
Let the total area be A.
Area of each section will be A/10
So probability of landing on 3 will be = (A/10) / A = 1/10
So the correct answer will be option C
Answer:
x = 2.5y
Step-by-step explanation:
If a cow can give 5 gallons of milk after eating 2 pounds of grass.
Let's consider 'x' is the number of pounds of grass it eats and 'y' is the number of gallons of milk the cow gives.
Hence,
5y = 2x
We will simplify it to get what x equal to y by dividing 2 on both side we find,
x = 2.5y
x is equal to 2.5 y
By eating 1 pound of grass cow can give 2.5 gallons of milk.
