Answer 1

Answer:

7a+b-9c+17d

Step-by-step explanation:

-5 ( a-2b+3c -4d) - (-3) (4a -3b+2c-d)

Distribute

-5a+10b-15c+20d+12a-9b+6c-3d

Combine like terms

7a+b-9c+17d

Answer 2

7a + b - 9c + 17d

step-by-step explanation

(- 5)( a - 2b +3c - 4d ) - (-3)( 4a - 3b+2c - d )

- 5( a - 2b + 3c - 4d ) - (-3)( 4a - 3b + 2c - d)

Using Distributive property

- 5a + 10b - 15c + 20d + 12 a - 9b + 6c - 3d

Arranging like terms together

- 5a + 12a + 10b - 9b -15c + 6c + 20d -3d

7a + b - 9c + 17d

Answer:

4.5 cm

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

121.5 pi = 4/3 pi r^3

Divide each side by pi

121.5 = 4/3  r^3

Multiply each side by 3/4

3/4 *121.5 = 3/4 * 4/3  r^3

91.125 = r^3

Take the cube root of each side

(91.125)^ (1/3) = r^3 ^(1/3)

4.5 = r

5x - 4y + 2z :

5 (-8) - 4 (3) + 2 (-4)

-40 - 12 - 8

- 60

3x + 2 (x - 4) = 6x - 8 - x

3x + 2x -8 = 6x - 8 - x

5x - 8 = 5x - 8

Since both sides are equal, it has infinitely many solutions.

What is the volume of the following rectangular prism?

Answers

The volume of a rectangular prism is a measurement of the occupied units of a rectangular prism. ... It is also defined as the number of units used to fill a rectangular prism. The volume of the rectangular prism is equal to the area of the base times its height.
V of rectangular prism formula: L x W (some combine these two and say “area of the base”) x H.
They gave you the “area of the base” as 25/4 is in units squared. So you just need to multiply 25/4 x 8/5 = 200/20 which is 10 units cubed.
If decimals are easier 25/4 = 6.25 and 8/5 = 1.6. So 6.25 x 1.6 = 10 units cubed.

$18.75 to $18.60 identify the percent of change as an increase or decrease . then find the percent of change round to the nearest tenth of a percent , if necessary

Answers

Answer:

0.8%

Step-by-step explanation:

There is a decrease in percentage by 0.8%.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

The given decimal numbers are $18.75 and $18.60.

We know that, percentage change = (Original price-New price)/Original price ×100

= (18.75-18.60)/18.75 ×100

= 0.15/18.75 ×100

= 0.008×100

= 0.8%

Therefore, there is a decrease in percentage by 0.8%.
