6k ÷ 7 = -3<br> Solve for k
fomenos

Answer:

k = -3.5

Step-by-step explanation:

6k ÷ 7 = -3

Multiply 7 to both sides

6k = -21

Divide both sides by 6

6k/6 = -21/6

k = -3.5

To check if the answer is correct or not, you can always plug in -3.5 for k in the equation.

6(-3.5) ÷ 7 = -3

-21 ÷ 7 = -3

-3 = -3

-3 equals -3 so it is correct that k = -3.5

16. Solve for "x".<br> a. 6<br> b. 100<br> c. 36
erastovalidia [21]

Answer:

A. 6

Step-by-step explanation:

Using the Pythagorean theorem which states that: <u>Hypotenus² = Opposite² + Adjacent²</u>

Where: hypotenus = 10, opposite = x, adjacent = 8

So:

{10}^{2}  =  {x}^{2}  +  {8}^{2}

Solving for x

100 =  {x}^{2}  + 64

Collect like terms to make x the subject of formula

100 - 64 =  {x}^{2} →36 =  {x}^{2}

36 =  {x}^{2} ⟹ {x}^{2}  = 36

square root both sides of the equation to find the value of x

\sqrt{ {x}^{2} }  =  \sqrt{36} →x = 6

Therefore: Option A is correct
