Last month,Margo bought a tree that grows 2.5cm each day.It was 5cm tall when she bought it and now it 65cm tall. Write a equati
1 answer:
Answer:
The equation to determine the number of days Margo has owned the plant is .
Step-by-step explanation:
Given:
Actual length of the tree = 5 cm
Current length of the tree = 65 cm
Per day growth Rate of plant = 2.5 cm
Let number of days she owned the plant be 'x'
Now We can say that,
Current length of the tree is equal to sum of Actual length of the tree and Per day growth Rate of plant multiplied by number of days she owned the plant.
Farming the above sentence in equation form we get;
Hence the equation to determine the number of days Margo has owned the plant is .

Answer: B. 1.1; -1.4.
Solution:
we have been asked to find
The expression is equivalent to
we can simplify the given expression as below
Hence the simplified expression , equaivalent to the given expression is 1/2.
<em>Note: I am assuming the first equation is:</em>
<em>x+y = 3</em>
Answer:
The solution to the system of equations is:
(x, y) = (-2, 36)
Therefore, the x-coordinate of the solution of the system
x = -2
Step-by-step explanation:
Given the system of equations
subtracting the equations
solve -2y for y
Divide both sides by -2
For x+y=34 plug in y = 36
Subtract 36 from both sides
Simplify
Thus, the solution to the system of equations is:
(x, y) = (-2, 36)
Therefore, the x-coordinate of the solution of the system
x = -2
