Answer: The reason why this is the answer is because 4 out of 20 (4/20) is 0.2, so 16 out of 20 (16/20) is 0.8
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the relation between the total number of candies (y) and number of bags (x) is,
y = mx + b
Here, b = Extra pieces of candies sitting outside the box.
m = Candies per box
From the question,
x = 4,(Number of bags are 4)
y = 4m + 4
If total number of candies are 36,
36 = 4m + 4
4m = 32
m = 8
Each bag will contain 8 candies.
Therefore, equation representing the relation is,
y = 8x + 4
Now complete the table by substituting the values of x,
x y
1 12
2 20

4x + 8y = 20
- 4x + 2y = -30
find y first
in order to find y eliminate x
add the two equations together
4x+-4x+8y+2y= 20+-30
4x-4x+8y+2y= 20-30
10y= -10
divide both sides by 10 to get y by itself
10y/10= -10/10
y= -1
find x by using the substitution method
- 4x + 2y = -30
-4x+2(-1)=-30
-4x-2= -30
move -2 to the other side
sign changes from -2 to +2
-4x-2+2= -30+2
-4x= -28
divide both sides by -4
-4x/-4= -28/-4
x= 7
answer:
(7,-1)
Answer:
Gymnasts always perform on padded mats because
- The padded floor increase the time. The time changes because the padded floor extends the time of the collision. The force is reduced by this time change.
Step-by-step explanation:
- The Impulse Momentum Theorem states that the change in momentum of an object is equal to the impulse applied on it.
J = Δ P ---- (1)
Where J is impulse and Δ P is change in momentum
We also know that impulse is the net force applied on a object which is represented by the following equation:
J = F ΔT
Putting this equation in equation (1), we get:
F ΔT = Δ P
So, this shows when the time is increases then the impulse decreases due to which the gymnasts always perform on padded mats.
we know that
