How do you solve -2 = t/3 - 11?

andrey2020 [161]

<h2>Answer:</h2><h2> $\boxed{t=27}$ </h2><h2></h2><h2>Solution Steps:</h2>

______________________________

<h3>1.) Multiply both sides of the equation by 3:</h3>

$\frac{t}{3}$ × $3=t$

$-11$ × $-3=-33$

- We do this because we need to get x alone and separate from fraction from.

Equation at the end of Step 1:

$-6=t-33$

<h3>2.) Add 33 to both sides:</h3>

$-33+33=$ Cancels Out

$-6+33=27$

- We do this to cancel out an extra numbers in order to get only x alone with 1 number on the opposite side of the equal.

If A=(0,0) and B=(8,2), what is the length of AB

NeX [460]

Answer:

$\boxed{\sf Distance_{AB}= 8.24 \ units }$

Step-by-step explanation:

Here two points are given to us and we need to find the distance between the two points . The given points are , A(0,0) and B(8,2) . The distance between the two points can be found out using the Distance Formula , which is ,

Distance Formula:-

$\sf\implies \green{ Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2}}$

Therefore on substituting the respective values ,we can find the Distance as ,

$\sf\longrightarrow Distance = \sqrt{ ( 0 - 8)^2 + (0-2)^2}$

Simplify the brackets ,

$\sf\longrightarrow Distance =\sqrt{ (-8)^2+(-2)^2}$

Square the numbers inside the squareroot ,

$\sf\longrightarrow Distance =\sqrt{ 64 + 4}$

Add the numbers inside the squareroot ,

$\sf\longrightarrow Distance = \sqrt{68}$

Find the value of squareroot,

$\sf\longrightarrow \boxed{\blue{\sf Distance = 8.24 \ units }}$

Hence the distance between the two points is 8.24 units .
