Answer: 294 square millimeters

Step-by-step explanation:

Each side of the cube is 7 mm.

First, find the area of one face. The formula for the area of a square is [tex]s^2[/tex]. 7 mm squared is 49 square millimeters.

A cube has 6 faces, so multiply the area of one face by 6. 49*6 = 294 square millimeters

Answer:

a=6

Step-by-step explanation:

distribute:

3a-15-6=-15

combine like terms:

3a-21=-15

add 21 to each side:

3a=6

divide by 3:

a=2

[tex]\text{Apply Pythagorean theorem,}\\ \\~~~~~~~x^2 = 25^2 +75^2\\\\\implies x =\sqrt{25^2 +75^2}\\ \\\implies x = \sqrt{625+5625}\\\\\implies x = \sqrt{6250}\\\\\implies x =\sqrt{625 \times 10}\\\\\implies x = \sqrt{25^2 \times 10}\\\\\implies x = 25\sqrt{10}[/tex]

Hi Student!

Usually the first step that I take for any problem would be to gather any important information that would be needed in the problem.  However, for this problem, it is pretty straight forward because we just need to solve for the unknown which is x.

Add 3 to both sides

Divide 8 from both sides

For the first equation, we were able to solve for x and get that the solution for the unknown is 1.25

Subtract 5 from both sides

Divide both sides by 7

For the second equation, we are able to solve for x and get that the solution for the unknown is 19/7

Subtract 6 from both sides

Divide both sides by 4

For the final equation, we are able to solve for x and get that the solution for the unknown is -0.25

Answer:

1) [tex]x=\frac{5}{4}=1\frac{1}{4}[/tex]

2) [tex]x=\frac{19}{7}=2\frac{5}{7}[/tex]

3) [tex]x=-\frac{1}{4}[/tex]

Step-by-step explanation:

1) 8x - 3 = 7

1. Group all constants on the right side of the equation

[tex]8x-3=7[/tex]

Add 3 to both sides:

[tex]8x-3+3=7+3[/tex]

Simplify the arithmetic:

[tex]8x=7+3[/tex]

Simplify the arithmetic:

[tex]8x=10[/tex]

2. Isolate the x

[tex]8x=10[/tex]

Divide both sides by 8:

[tex]\frac{8x}{8}=\frac{10}{8}[/tex]

Simplify the fraction:

[tex]x=\frac{10}{8}[/tex]

Find the greatest common factor of the numerator and denominator:

[tex]x=\frac{5\cdot 2}{4\cdot 2}[/tex]

Factor out and cancel the greatest common factor:

[tex]x=\frac{5}{4}[/tex]

2) 5 + 7x = 24

1. Group all constants on the right side of the equation.

[tex]5+7x=24[/tex]

Subtract 5 from both sides:

[tex]5+7x-5=24-5[/tex]

Group like terms:

[tex]7x+5-5=24-5[/tex]

Simplify the arithmetic:

[tex]7x=24-5[/tex]

Simplify the arithmetic:

[tex]7x=19[/tex]

2. Isolate the x

[tex]7x=19[/tex]

Divide both sides by 7:

[tex]\frac{7x}{7}=\frac{19}{7}[/tex]

Simplify the fraction:

[tex]x=\frac{19}{7}[/tex]

3)  5 = 6 + 4x

1. Swap sides

[tex]5=6+4x[/tex]

Swap sides:

[tex]6+4x=5[/tex]

2. Group all constants on the right side of the equation

[tex]6+4x=5[/tex]

Subtract 6 from both sides:

[tex]6+4x-6=5-6[/tex]

Group like terms:

[tex]4x+6-6=5-6[/tex]

Simplify the arithmetic:

[tex]4x=5-6[/tex]

Simplify the arithmetic:

[tex]4x=-1[/tex]

3. Isolate the x

[tex]4x=-1[/tex]

Divide both sides by 4:

[tex]\frac{4x}{4}=\frac{-1}{4}[/tex]

Simplify the fraction:

[tex]x=\frac{-1}{4}[/tex]

Why learn this:

Linear equations cannot tell you the future, but they can give you a good idea of what to expect so you can plan ahead. How long will it take you to fill your swimming pool? How much money will you earn during summer break? What are the quantities you need for your favorite recipe to make enough for all your friends?

Linear equations explain some of the relationships between what we know and what we want to know and can help us solve a wide range of problems we might encounter in our everyday lives.

---------------------

Terms and topics

The most common use of linear equations is to solve problems involving an unknown variable, generally (but not always) x, and a known constant.

Solving linear equations requires isolating the unknown variable on one side of the equation and simplifying the remainder. Anything done to one side of the equation must also be done to the other when simplifying.

An equation of:

[tex]ax+b=0[/tex]

A typical linear equation with one unknown is in which a and b are constants and x is the unknown variable. In this case, we would isolate x by removing b from both sides of the equation before solving for it. We'd then multiply both sides of the equation by a, yielding the following result:

[tex]x = -\frac{b}{a}[/tex]

Answer:

1. unknow

2. mean median range spread average

3. the bike Ville is more expensive in everything

Using Average, the prices of bicycles at two stores are compared.

Average is the" sum of observations divided by total number of observations".

According to the question,

The price of bicycles at two stores are shown.

Bikeville:                  140 160 800 235   250 450 80 115 220 250 96  290

Discount Bicycles:   50  180  300  110   120  150 155 285 120 200 70 175 95

Average of bikeville = [tex]\frac{sum of observations}{Total number of observation}[/tex]

= 140 + 160 + 800 + 235 + 250 + 450 + 80 + 115 + 220+250+96+29

= 3086

Average of bikeville= 3086/12

= 257.167

Average of Discount of bicycles:

( 50 +180+100+110+120+150+155+285+

120+150+155+285+120+200+70+175+95)     =2720

= 2720/15

=181.33

Average of Discount of bicycles is 181.33.

Hence, using Average the prices of bicycles at two stores are compared.

Answer:

First we have to turn it into slope intercept form which is y = mx  + b.

we need to isolate y. To do this, we have to subtract 8x from both sides to get

-y = -8x - 24

Answers:  585,  587, and 593

Basically everything except 599

==============================================================

Why?

Those answers in bold are closer to 590 than they are to 580 or 600. When rounding to the nearest ten (not tenth) we look at the units digit. If it is 5 or larger, then we bump the tens digit up by 1 and replace the units digit with a 0.

This explains why 585 and 587 round to 590

The number 599 rounds to 600 for similar reasoning, but we cross it off the list since we want 590.

The number 593 rounds to 590 because the 3 in the units digit isn't 5 or larger. So we just replace the 3 with 0 and keep everything else as is.
