Answers

Answer:

216

Step-by-step explanation:

The formula of finding the surface is length * width * height or LxWxH.

what is-12x + 16 – 4x = -112

Answers

Answer:

[tex]x=8[/tex]

Step-by-step explanation:

First, I wanna point out a minor mistake, are we supposed to figure out x?

If we are, let's start.

[tex]-12x+16-4x=-112.[/tex]

We don't need the [tex]16.[/tex]

We subtract the 16 from both sides.

SImplify, =[tex]16x=128[/tex]

Also, group like terms, and add similar elements.

Answer:

x = 8

Step-by-step explanation:

-12x + 16 - 4x = -112

Combine like terms on the left side.

-16x + 16 = -112

Subtract 16 from both sides.

-16x = -128

Divide both sides by 16.

x = 8

Check:

-12x + 16 - 4x =

= -12(8) + 16 - 4(8)

= -96 + 16 - 32

= -80 - 32

= -112

-112 = -112

x = 8 is correct.

Answer: x = 8

Answers

Answer:

66 cm (Option B)

Step-by-step explanation:

The formula for the circumference of a circle is C = 2πr, so plug the values into the formula.  The radius, (r) of a circle is one half of the diameter, so split 21 is half to get a radius of 10.5.  Use 3.14 for π.  

C = 2πr

C = 2(3.14)(10.5)

C = 6.28 × 10.5

C = 65.94

Rounded to the nearest unit, you get a answer of 66 cm.

Sandy mixed together 9 gallons of one brand of juice and 8 gallons of a second brand of juice,
which contains 48 percent real fruit juice. Find the percent of real fruit juice in the first brand if
the mixture contained 30 percent real fruit juice. Which of the following equations could be used
to solve this?

Answers

Answer:

14 %   pure juicecomes from  first brand

Step-by-step explanation:

Mixture:

17 gal 30% contains:  17x 30% = 5.10 gal pure juice

 Second brand:

8 gal 48% contains:  8x40% =  3.84   gal pure juice

 

5.10 − 3.84 = 1.26   gal

1.26   gal is  coming  from 9 gal of first  brand

The percentage of first brand  is:

(1.26/9) x100  =  14 %   pure juice.
