Jasmine planted a 5-foot tree. After one year, she measured it and found out that the tree had grown 20% of its original height. How tall was the tree after one year. Pleade help very confused​

6 feet

Step-by-step explanation:

Find what 20% of 5 is and add the result to its original height; 5.

hope this helps:)

6 foot

Step-by-step explanation:

You want to use the equation

5(n)

n will be 0.20 since the tree grew by 20% of its original height

5(0.20)=1

Now add 1 with 5

1+5

6

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
