Now let’s practice what you have learned. Solve the equation. 4y – 4 = 28

laiz [17]

Answer:

Step-by-step explanation:

4y-4=28

4y=28+4

4y=32

y=32/4

y=8

now plug in 8 for y and check the equation true:

4y-4=28

4*(8)-4=28

32-4=28

28=28

So, y is equal to eight 8

Use the recursive relationship to complete the next two rows of Pascal's triangle. Row 5: 1 _ _ _ _ 1 Row 6: 1 _ _ _ _ _ 1

frosja888 [35]

Answer:

1 5 10 10 5 1 Row 5

1 6 15 20 15 6 1 Row 6

Recursive relationship:

Each row has number of positions = row number + 1. The Row 0 is always 1.

The first and last number in each row is 1, the number in the second position and the penultimate corresponds to the number of the row. The middle numbers correspond to the sum of the two numbers in the top row. The resulting number from the addition is located in the middle of the numbers added in the next row.

Step-by-step explanation:

The pascal's triangle

* Row 0 = 1

* Row 1 = 1 1

1 Row 0

1 1 Row 1

Since there are only two positions, the first and last are 1.

*Row 2 = 1 _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

2 is the sum of 1 + 1 and we place it in the next row between the added numbers 1 and 1.

* Row 3 = 1 _ _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

1 3 3 1 Row 3

1 + 2 = 3 (the row number and the and adding the numbers from the previous row)

* Row 4 = 1 _ _ _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

1 3 3 1 Row 3

1 4 6 4 1 Row 4

1 + 3 = 4 (the row number)

3 +3 = 6

* Row 5 = 1 _ _ _ _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

1 3 3 1 Row 3

1 4 6 4 1 Row 4

1 5 10 10 5 1 Row 5

1 + 4 = 5

4 + 6 = 10

* Row 6 = 1 _ _ _ _ _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

1 3 3 1 Row 3

1 4 6 4 1 Row 4

1 5 10 10 5 1 Row 5

1 6 15 20 15 6 1 Row 6

1 + 5 = 6

5 + 10 = 15

10 + 10 = 20

Scott brought $23.25 to the art supply store. He bought a brush, a sketchbook, and a paint set. The brush was one fourth as much

fenix001 [56]

Answer:

Paint set cost = 10.5 , Sketch book cost = 7 , Brush cost = 1.75

Step-by-step explanation:

Let the cost of paint set be = p

Cost of sketchbook 's' = (2 / 3) p

Cost of brush 'b' = 1/4th of s = 1 / 4 [ (2 / 3) p ] = (1 / 6) p

Total expenditure = Money bought - Money left = 23.25 - 4 = 19.25

Total expenditure = Cost of (pen + of sketchbook + of brush) = p + s + b

= p + (2 / 3) p + (1 / 6) p = 19.25 → p + 2p / 3 + p / 6 = 19.25

( 6p + 4p + p ) / 6 = 19.25 → 11p / 6 = 19.25 → p = ( 19.25 x 6 ) / 11

p = 10.5 ; s = (2 / 3) p = 2 / 3 (10.5) = 7 ; b = (1 / 6) p = 10.5 / 6 = 1.75
