The remaining plant food is: 1 7/12 kg
Step-by-step explanation:
Given
Total Plant food = 3 1/2 kg
Plant food used on Strawberry Plants = 1 2/3 kg
Plant food used on tomato Plants = 1/4 kg
We will first calculate the total food plant used and then subtract the used plant food from the total plant food.
So,
Now,

Answer:
x = - 3, y = 4
Step-by-step explanation:
Given the 2 equations
- 2x + y = 10 → (1)
y = - x + 3 → (2)
Substitute (2) into (1), that is
- 2x - x + 3 = 10 ( multiply through by 3 to clear the fraction )
- 6x - x + 9 = 30
- 7x + 9 = 30 ( subtract 9 from both sides )
- 7x = 21 ( divide both sides by - 7 )
x = - 3
Substitute x = - 3 into (2) for corresponding value of y
y = - (- 3) + 3 = 1 + 3 = 4
solution is x = - 3, y = 4
The formula for conditional probablity states that
Since we know both numerator and denominator, we only need to plug in the values:
