Well this is easy.

We have linear inequality,

$3x+3 < 93 -6$

Simplifying this a bit to get,

$3x < 84$

Divide by 3 (both sides),

$x < 28$

Or with interval notation, $x\in (-\infty, 28)$ .

Hope this helps. :)

Answer:

Tick:

- the coefficient of the second term is -5

- the coefficient of the fourth term is -10

Explanation:

The coefficient of an expression is simply the number placed before and multiplying the variable (e.g. 10x ; the coefficient is 10, the variable is x)

Hope this makes sense. Feel free to inquire further if need be!

What is 6 divided by a number that will give you 12

AURORKA [14]

▶︎◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◀︎

$Hello$ $There!$

We need to find what number, if 6 is divided by it, gives us 12.

This isn't hard, I promise! I am going to take you through a few steps, and we'll find the answer.

Are you ready? Then let's begin...:)

$Procedure:$

✦ We can think about it as: 6 divided by what number gives us 12?

(let the number be z)

$^6/_z=12$

Multiply both sides by z

$6=12z$

Divide both sides by z

$z=^6/_{12}$

Which is the same as

$z=^1/_2$

hope it's helpful!
wishing you a great day!

Answer:

m∠ADC=55°

Step-by-step explanation:

step 1

Find the value of x

we know that

m∠CDE+m∠EDF=180° ----> by supplementary angles (form a linear pair)

substitute the given values

$(2x+1)\°+(x-7)\°=180\°$

solve for x

$2x+x=180+6$

$3x=186$

$x=62$

step 2

Find the measure of angle ∠ADC

we know that

m∠ADC=m∠EDF ----> by vertical angles

m∠EDF=(x-7)°

substitute the value of x

m∠EDF=(62-7)°=55°

therefore

m∠ADC=55°
