Answer:

x=−12

Step-by-step explanation:

Let's solve your equation step-by-step.

7(x+3)=5x−3

Step 1: Simplify both sides of the equation.

7(x+3)=5x−3

(7)(x)+(7)(3)=5x+−3(Distribute)

7x+21=5x+−3

7x+21=5x−3

Step 2: Subtract 5x from both sides.

7x+21−5x=5x−3−5x

2x+21=−3

Step 3: Subtract 21 from both sides.

2x+21−21=−3−21

2x=−24

Step 4: Divide both sides by 2.

−24

Answer:X=-12

Step-by-step explanation:Simplify both sides of the equation

7(x+3)=5x−3

(7)(x)+(7)(3)=5x+−3(Distribute)

7x+21=5x+−3

7x+21=5x−3

Subtract 5x from both sides

7x+21−5x=5x−3−5x

2x+21=−3

Subtract 21 from both sides

2x+21−21=−3−21

2x=−24

Divide both sides by 2

2x/2=-24/2

X=-12

Triangle A″B″C″ is formed using the translation (x + 2, y + 0) and the dilation by a scale factor of one half from the origin. W

Dafna1 [17]

Answer:

A. segment A double prime B double prime = segment AB over 2

Step-by-step explanation:

Triangle ABC with coordinates of:

A = (-3, 3), B = (1, -3), C = (-3, -3)

Translation (x + 2, y + 0), coordinates will be:

A' = (-1, 3), B = ( 3, -3), C = (-1, -3)

Dilation by a scale factor of 1/2 from the origin, coordinates will be:

A'' = (-0.5, 1.5), B'' = (1.5, -1.5), C= (-0.5, -1.5)

Let's find the length of AB and A''B'' using distance formula

d = √(x2-x1)² + (y2 - y1)²

AB = √(1-(-3))² + (-3 -3)² = √4²+6² = √16+36 = √52 = 2√13
A''B'' = √(1.5 - (-0.5)) + (-1.5 - 1.5)² = √2²+3² = √13

We see that

AB = 2A''B''

Now the answer options:

A. segment A double prime B double prime = segment AB over 2

Correct

B. segment AB = segment A double prime B double prime over 2

Incorrect. Should be AB = A''B''*2

C. segment AB over segment A double prime B double prime = one half

Incorrect. Should be AB/A''B'' = 2

D. segment A double prime B double prime over segment AB = 2

Incorrect. Should be A''B''/AB = 1/2

Fred takes 3 hours to dig a garden. It takes Jason 5 hours to

Irina18 [472]

It takes them 1 7/8 hrs to complete the job together.

How:
Fred = 3 hrs
Jason = 5 hrs

1/3x + 1/5x = 1/x

3x x 5x = 15 —> 3x/15 + 5x/15 = 15/15

3x + 5x = 8x —> 8x/15 = 1.875 = 1 7/8 hrs

Evaluate 7+2 times 4

wel

Are there any parentheses in this equation? that would determine what you do first.

if it is (7+2)•4 your answer is 36.
if it is 7+2•4, then your answer would become 7+8, which is 15.
