Answer:

x = 19

Step-by-step explanation:

Since C is between B and D , then

BC + CD = BD , substitute values

8x + 13 + 12x - 73 = 320 , that is

20x - 60 = 320 ( add 60 to both sides )

20x = 380 ( divide both sides by 20 )

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the dimension of the prism is not given. However, the following steps can serve as a guide for you.

The volume of a rectangular prism is calculated as thus:

[tex]Volume = Length * Width * Height[/tex]

So, Take for instance

[tex]Length = 2\ in[/tex]

[tex]Width = 3\ in[/tex]

[tex]Height = 4\ in[/tex]

The Volume would be:

[tex]Volume = 2\ in * 3\ in * 4\ in[/tex]

[tex]Volume = 24\ in^3[/tex]

The sum of 20.7 and a number is 50.5.

Jess is painting his car. He's created a purple color that uses red paint and blue paint in a ratio of 6:5. Jess uses 15
pints of blue paint. How many pints of paint does he use in total?
A
18
B
33
С
11
D
26

Answers

Answer:

B.) 33

Step-by-step explanation:

15/5=3

6x3=18

18+15=33

The ratio shows how many times one value is contained in another value.

If the ratio of Red and blue is 6:5 and uses 5 pints of blue color.

The total pints of paint used in total is 33 pints.

What is a ratio?

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

The ratio of minutes and minutes in 1 hour is 60 : 3600

We have,

Purple color:

Red : Blue = 6 : 5

Let,

Red colour = 6x

Blue color = 5x

Now,

Blue color = 15 pints

5x = 15 pints

x = 15/3

x = 3 pints _______(1)

Now,

Total color.

= Red + Blue

= 6x + 5x

= 11x

Now,

From (1) we get,

= 11x

= 11 x 3

= 33

Thus,

If the ratio of Red and blue is 6:5 and uses 5 pints of blue color.

The total pints of paint used in total is 33 pints.

Answer:

x= -3

Step-by-step explanation:

Distribute 4(2-4x) which leaves you with 8-16x-3x=65

combine the like terms which leaves you with 8-19x=65

subtract 8 from both sides 8-19x-8=65-8 which leaves you with -19x=57

lastly divide -19 from both sides which leaves you with x= -3
