The justifications are in the order distributive property, associative property of addition, Combine like terms, Addition property of equality and multiply by LCD.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given equation is,

5(2x + 1) = 2 (4x - 7) + 3

Using distributive property, a(b + c) = ab + ac

10x + 5 = 8x - 14 + 3

10x + 5 = 8x - 11  [associative property of addition]

10x - 8x + 5 = -11

2x + 5 = -11  [Combine like terms]

2x + 5 - 5 = -11 - 5

2x = -16 [ Addition property of equality]

2x / 2 = -16/2

x = -8  [multiply by LCD]

Hence the justifications are done.

Answer:

<VPQ = 83°

< VPU = 35°

Angles on a straight line adds up to 180°

Therefore 35°+ 62°= 97°

180- 97= 83°

Answer:

$42.83

Step-by-step explanation:

1: Subtract the amount they have by the amount they need.

1328-43= $1,285.

2: Divide amount they need ($1,285) by the total staff members (30).                Hence the equation is 1285 ÷ 30

3: Whatever answer you get from that equation is the answer

1285 ÷ 30 = $42.83

When you divide, you are setting the amount each staff member needs to donate by seeing how much money 30 people can give (equally) that adds up to 1285.

Hope this helps :)

Answer:

x = 12

Step-by-step explanation:

The 2 angles add up to 90 degrees, so 3x + x + 42 = 90

3x + x + 42 = 90

Subtract 42 from both sides:

3x + x = 48

3x + x = 4x, so

4x = 48

Divide both sides by 4:

x = 12

Answer:

C = 106.76 cm

Step-by-step explanation:

In the diagram, we are given the diameter (d), which is 34 cm.  Using the formula you are given, we know circumference is 3.14 × d

C = 3.14 × d

C = 3.14 × (34)

C = 106.76 cm

The circumference is around 106.76 cm

Answer:

x = -2

y = -1

Step-by-step explanation:

y - 2x = 3 and y - x = 1

Subtract the second equation from the first

   y - 2x = 3

- ( y -  x  = 1)

––––––––––

       -x = 2

Multiply both sides by -1

x = -2

Sustitute x = -2 into the first equation

y - 2(-2) = 3

y + 4 = 3

Subtract 4 from both sides

y = -1

Answer:

$350.00

Step-by-step explanation:

$280 = 80%

$3,5 = 1%

$350 = 100%

if $280 is 80%

then every percent is $3,5

original price is 100%

so multiply 3,5 by 100

then you'll get 350

Pine tree measure = 40 feet in height

Step-by-step explanation:

This is because the Flag pole of 50 feet in measure cast a shadow of 15feet and nearby to the pine tree (meaning same dilation would occur for such shadow) where pine tree shadow is given measure of 12 feet.

Flag Pole multiplier = 50 / 15 = 3 1/3

Pine Tree true measure = 12 x 3 1/3 = 40 feet in height

Answer:

3 Cups, 16 ft

Step-by-step explanation:

22. We know that this makes 8 servings. Divided by 2 will get us 4, which added to 8 creates 12 servings.

Initially only 2 cups of lemon juice are required. Divided by 2 is 1.

2 + 1 = 3

3 Cups are needed.

23. We know that to find an area of a triangle, the equation is Base x Height divided by 2.

We first multiply 72 by 2 to find the initial value.

72 * 2 = 144

144/9 = Base

=16
