Answer:

x=−3

Step-by-step explanation:

2(6x+1)−4(x−5)=−2

Step 1: Simplify both sides of the equation.

2(6x+1)−4(x−5)=−2

(2)(6x)+(2)(1)+(−4)(x)+(−4)(−5)=−2(Distribute)

12x+2+−4x+20=−2

(12x+−4x)+(2+20)=−2(Combine Like Terms)

8x+22=−2

8x+22=−2

Step 2: Subtract 22 from both sides.

8x+22−22=−2−22

8x=−24

Step 3: Divide both sides by 8.

8x/8=−24/8

Anne and Willow are reading the copy of the same magazine for an assignment.
Kamila [148]

Answer:

Page number 74

Step-by-step explanation:

Let

x ---> the number of days

y ---> the number of pages read

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

we have

<em>Anne</em>

The slope is equal to

m=20\ \frac{pages}{day}

The y-intercept is equal to

b=14\ pages

substitute

y=20x+14 ----> equation A

<em>Willow</em>

The slope is equal to

m=22\ \frac{pages}{day}

The y-intercept is equal to

b=8\ pages

substitute

y=22x+8 ----> equation B

equate equation A and equation B

22x+8=20x+14

solve for x

22x-20x=14-8\\2x=6\\x=3\ days

Find the value of y

substitute the value of x in equation A or equation B

equation A

y=20(3)+14=74\ pages

equation B

y=22(3)+8=74\ pages

A square with one side length is represented by the expression 4(2x+3)+16+8x. Use the properties of operations to write three di
finlep [7]

Answer:

The other sides of the square are

8x+12+16+8x,(8x+8x)+(12+16) and 16x+28  

Step-by-step explanation:

Square:

  1. The all sides of a square equal.
  2. The sum of four angles is 360°.
  3. The diagonals bisect each other.
  4. The length of diagonals are equal.

Distributive property:

a(b+c)= ab+ac

Commutative property:

a+b= b+a

Like terms:

Like terms are terms that have the same variables and the power of the variable also same.

Given the length of the side is

=4(2x+3)+16+8x

=4.2x+4.3+16+8x [ Apply distributive property]

=8x+12+16+8x

=(8x+8x)+(12+16)   [ separating like terms]

=16x+28                [Adding like terms]

The other sides of the square are

8x+12+16+8x,(8x+8x)+(12+16) and 16x+28
