First off, the action would be to multiply both sides by 4. Since 4 is the reciprocal of 1/4, should multiply by that.

Then, Since we are multiplying it would be the multiplication property of equality, no tricks there.

Hope this helps!

A) Action: multiply both sides by 4. 

Have a look: 

(x/4)x4=16x4 
x=64 

As you can see, the value of x can be found by multiplying 4 on both sides.

Hope I helped :)

the length of a rectangle is 4 more than 3 times the width. If the perimeter of the rectangle is 18.4cm, what is the area of the
antoniya [11.8K]

Answer:

A = 10.27cm²

Step-by-step explanation:

Let's represent the width as x,

therefore since the length is 4 more than 3 times the width, it can be represent as 3x + 4,   Perimeter = 18.4cm

Perimeter of a rectangle = 2(L + B)

18.4= 2(3x+4+x)\\18.4= 6x+8+2x\\18.4-8=6x+2x\\10.4=8x\\x=\frac{10.4}{8}\\x=1.3

width = 1.3cm

Length = 3x + 4 = 3*1.3 + 4 = 7.9cm

Area of a rectangle = length x width

A = 7.9 * 1.3 = 10.27cm²

Zepler [3.9K]

Answer:

The equation that can be used to represent the total number of collector's card Stacy has in 'x' weeks is .

y = 3 + 2x

Completed question;

Stacy has 3 collector's cards. She receives 2 more cards each week that she volunteers at the student center. Let x = the number of weeks. Let y = the number of collector's cards. Write the equation that can be used to represent the total number of collector's card Stacy has in 'x' weeks.

Step-by-step explanation:

Given:

The number of cards she have initially = 3

The number of cards receive every week = 2

the number of week = x

the total number of collector's card after x weeks = y

The total number of collector's card will be equal to sum of the number of cards she had initially and the number of cards receive every week multiplied by number of weeks.

This can be written as;

y = 3 + 2x

Since there is no more details given in question as to what to derive;

we can conclude that;

The equation that can be used to represent the total number of collector's card Stacy has in 'x' weeks is .

y = 3 + 2x

In case any of the variables is given, simple substitution can be used to derive the other variable.
