Step-by-step explanation:

1. 0 seconds and 16 feet.

$2(0) + 16$
$0 + 16$

$16$

2. 1 second and 18 feet.

$2(1) + 16$
$2 + 16$
$18$

3. 2 seconds and 20 feet.

$2(2) + 16$
$4 + 16$
$20$

4. 3 seconds and 22 feet.

$2(3) + 16$
$6 + 16$
$22$

5. 6 seconds and 28 feet.

$2(6) + 16$
$12 + 16$
$28$

Therefore, the answer is 2t + 16.

Solve for n.<br> 3/4 x n = 1

cestrela7 [59]

3/4 times n=1

remember that when you multiply 3/4 by 4/3 you get 12/12=1 so it simplifies
remember that you can do anything to an equation as long as you do it to both sides

3/4 ties n=1
multiply both sides by 4/3 to clar fraction
12/12 times n=4/3 times 1
1 times n=4/3
n=4/3

answer is n=4/3 or 1 and 1/3

If x^2 - 6xy = z - 9y^2, make x the subject of the formula

alukav5142 [94]

$~~~~x^2-6xy=z-9y^2\\\\\implies x^2- 2\cdot x\cdot 3y + (3y)^2 - (3y)^2 = z-9y^2\\ \\\implies (x-3y)^2 -9y^2 = z-9y^2\\\\\implies (x-3y)^2 = z\\\\\implies x - 3y =\pm\sqrt z\\\\\implies x = 3y\pm\sqrt z$
