If point W is -4,-2 and point V is -2,-2 what is the length of VW
Helen [10]

Answer:

2 units

Step-by-step explanation:

The length of VW is just the distance between the two coordinates. You could use the distance formula, or an easier and faster way would be to recognize that since both points have the same y-coordinate, the distance between them will just be the distance of the x-coordinates. The absolute value of -4 and -2 is 2, so the length of VW is 2 units.

Hope this helped! ;)

Solve the system of equations by substitution.<br> y = 5x - 13<br> 4x + 3y = 18<br> The solution is
Rudik [331]

Answer:

x=3 and y=2

Step-by-step explanation:

1.) 4x+3(5x-13)=18

expand into 4x+15x-39=18

18+39= 57

15x+4x= 19x

57/19= 3 so x=3

substitute 3 into y= 5x - 13

and you get 2 so y=2

4x + 3(4x + 7) = 4(7x + 3)​
Natasha2012 [34]

Answer: 1

Step-by-step explanation:4x + 3(4x + 7) = 4(7x + 3) + -3

Reorder the terms:

4x + 3(7 + 4x) = 4(7x + 3) + -3

4x + (7 * 3 + 4x * 3) = 4(7x + 3) + -3

4x + (21 + 12x) = 4(7x + 3) + -3

Reorder the terms:

21 + 4x + 12x = 4(7x + 3) + -3

Combine like terms: 4x + 12x = 16x

21 + 16x = 4(7x + 3) + -3

Reorder the terms:

21 + 16x = 4(3 + 7x) + -3

21 + 16x = (3 * 4 + 7x * 4) + -3

21 + 16x = (12 + 28x) + -3

Reorder the terms:

21 + 16x = 12 + -3 + 28x

Combine like terms: 12 + -3 = 9

21 + 16x = 9 + 28x

Solving

21 + 16x = 9 + 28x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-28x' to each side of the equation.

21 + 16x + -28x = 9 + 28x + -28x

Combine like terms: 16x + -28x = -12x

21 + -12x = 9 + 28x + -28x

Combine like terms: 28x + -28x = 0

21 + -12x = 9 + 0

21 + -12x = 9

Add '-21' to each side of the equation.

21 + -21 + -12x = 9 + -21

Combine like terms: 21 + -21 = 0

0 + -12x = 9 + -21

-12x = 9 + -21

Combine like terms: 9 + -21 = -12

-12x = -12

Divide each side by -12.

x = 1

Simplifying

x = 1

The answer is 48 can someone explain how?
mestny [16]

Answer:

<h2>48</h2>

Step-by-step explanation:

(1)

apple × apple × 2apple = 54

2apple³ = 54    <em>divide both sides by 2</em>

apple³ = 27 → apple = ∛27

apple = 3

(2)

apple + apple × green_apple = 24   <em>substituite apple = 3</em>

3 + 3 × green_apple = 24        <em>subtract 3 from both sides</em>

3 × green_apple = 21         <em>divide both sides by 3</em>

green_apple = 7

(3)

strawberry - bannana - banana = 0 → strawberry = 2banana

(4)

strawberry + banana + cherry = 24     <em>substitute from (3)</em>

2banana + banana + cherry = 24

3banana + cherry = 24

(5)

apple + banana - cherry = -1          <em>substitute apple = 3</em>

3 + banana - cherry = -1         <em>subtr3 from both sides</em>

banana - cherry = -4

Add both sides of (4) and (5)

 3banana + cherry = 24

<u>+banana - cherry = -4       </u>

4banana = 20       <em>divide both sides by 4</em>

banana = 5

Substitute it to (4):

3(5) + cherry = 24

15 + cherry = 24      <em>subtract 15 from both sides</em>

cherry = 9

Substitute to the last equation:

3 + 5 × 9 = 3 + 45 = 48
