Which equation requires the division property of equality to be solved?

Ymorist [56]

Answer:

A. 201.6 = 11.2f

Step-by-step explanation:

we solve for each unknown to verify which equality will require the division property:

#A. 201.6 = 11.2f

$201.6=11.2f\\\\f=\frac{201.6}{11.2}=201.6\div 11.2\\\\=18$

Hence, division property used.

#B. 35.4=Z ÷ 3.1

$35.4=Z\div 3.1\\\\35.4=\frac{Z}{3.1}\\\\Z=35.4\times 3.1\\\\=109.74$

Hence, multiplication property used.

#C. t/3.2=15.1

$\frac{t}{3.2}=15.1\\\\t=15.1\times 3.2\\\\=48.32$

Hence, multiplication property used.

#D. 201.6 = 11.2+c

$201.6=11.2+c\\\\201.6-11.2=c\\\\c=190.4$

Hence, subtractionproperty used.

Please help need to get to 80%

Shalnov [3]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

First, start by converting 4 feet to inches. Note that 1 foot = 12 inches.

Set up a unit converter:

$4\ ft(\frac{12\ in}{1\ ft})$

The ft cancel out leaving us with:

$4*12\ in=48\ in$

Now, we can set up a scale factor...

$\frac{drawing}{real\ length}=\frac{8}{48}=\frac{1}{6}$

How could you solve for x in the problem 3x+7=-x-1

lukranit [14]

Hello there!

$3x+7=-x-1\\$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

First you had to subtract by 7 from both sides of the equation.

$3x+7-7=-x-1-7$

Simplify

$3x=-x-8$

Then you add by x from both sides of the equation.

$3x+x=-x-8+x$

Simplify

$4x=-8$

Divide by 4 from both sides of the equation.

$\frac{4x}{4}=\frac{-8}{4}$

Simplify it should be the correct answer.

$x=-2$

Answer⇒⇒⇒x=-2

Hope this helps!
