4✓6 × 3✓6<br>multiply and simplify <br>show work​
mafiozo [28]

Answer:

3

√

2

Explanation:

First put change the words into an equation:

√

3

×

√

6

Now you can multiply them together as you would normally multiply:

√

3

×

√

6

=

√

18

Now let's prime factor 18 and see if there are any squares that we can take out of it to simplify. All we have to see is if there are 2 numbers that are the same:

18

/ \

6

3

/ \

2

3

As you can see, we have a square:

3

×

3

=

9

So take

√

9

out of

√

18

. You should have:

√

9

√

2

But since

√

9

=

3

we can simplify further to make:

√

9

√

2

→

When truckers are on long-haul drives, their driving logs must reflect their average speed. Average speed is the total distance
KengaRu [80]

Answer:

0.500 hour

Step-by-step explanation:

Givens

<em><u>Distance</u></em>

  • Total Distance on the highway = 3hr * 60 miles / hr = 180 miles
  • Distance in the city = 20 miles
  • Total Distance = 180 + 20 = 200 miles

<em><u>Time</u></em>

  • Time on the highway = 3 hours
  • Time in the city = x

Formula

d /t = r

Solution

  • Average rate = 57.14
  • Total Distance / Total Time = average rate
  • 200 / (3 + x) = 57.14                               Multiply both sides by 3 + x
  • 200 = 57.14 * (3 + x)                               Remove the brackets
  • 200 = 57.14*3 + 57.14x                           Multiply the factors on the right
  • 200 = 171.42 + 57.14x                              Subtract 171.42 from both sides.
  • 200 - 171.42 = 171.42 - 171.42 + 57.14x   So the subtraction
  • 28.58 = 57.14x                                         Divide by 57.14
  • 28.57/57.14 = x
  • x = 0.500 hour                                        Answer

7.4x + 4.1(2x − 4) = −2.3(x − 6) − 21.6
loris [4]

Answer:

x = \frac{86}{179}

Step-by-step explanation:

7.4x + 4.1(2x − 4) = −2.3(x − 6) − 21.6

Multiply both sides by 10:

7.4x×10+4.1(2x-4)×10=-2.3(x-6)×10-21.6×10

Refine:

74x+41(2x-4)=-23(x-6)-216

Distributive Property:

74x+82x-164=-23(x-6)-216

Combine like terms:

156x-164=-23(x-6)-216

Distributive Property:

156x-164=-23x+138-216

Combine like terms:

156x-164=-23x-78

Add 164 to both sides:

156x-164+164=-23x-78+164

Simplify:

156x=-23x+86

Add 23x to both sides:

156x+23x=-23x+86+23x

Simplify:

179x=86

Divide both sides by 179:

\frac{179x}{179}=\frac{86}{179}

Simplify:

x = \frac{86}{179}
