Answer:

X=-33

Step-by-step explanation:

Comine multiplied terms into a single fraction 2(x+6)/3=-18

distribute 2x+13/3=-18

multiply all terms by the same value to eleminate fraction denominators 3(2x+12/3)=3(-18)

simplify 2x+12=-54

subtract 12 from both sides of the eqaution 2x+12-12=-54-12

simplify 2x=-66

divide both sides of the eqautions by the same term 2x/2=-66/2

simplify x=-33

Find the missing part.

Answer:

The answer is $a = \frac{15}{4}$

Step-by-step explanation:

We have to:

$cos(\theta) = \frac{adjacent\ side}{hypotenuse}$

So, if we take the 60 degree angle of the smallest triangle, we have to:

$cos(60) = \frac{a}{x}$

We do not know x. But if we take the sine of the angle of 30 degrees and the main triangle we have:

$sin(30) = \frac{x}{15}\\\\x =\frac{15}{2}$

Then:

$cos(60) = \frac{a}{\frac{15}{2}}$

$a = cos(60)\frac{15}{2}$

$a = \frac{15}{4}$

Some people advise that in very cold weather, you should keep the gas tank in your car more than half full. Lou's car had 5.9

Answer: $26.98

Step-by-step explanation:

1. You have the following information given in the problem above:

- Lou filled the tank with gas that cost $3.80 per gallon.

- Lou's car had 5.9 gallons in the 13-gallon tank.

2. Therefore, if he filled the tank, you can calculate the total amount of money Lou spent, by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.

3. Then, the result is:

$total=(13-5.9)(3.80)\\total=(7.1)(3.80)\\total=26.98$
