Answer:

Yes,

Step-by-step explanation:

You take 64 miles for 2 gallons and divide it by 2. And it leads up to 32 miles and 1 gallon. Now you divide that by 2 again and get 16 miles and 1/2 gallon. So, to check that you can take 16+16 and you get 32 and take 32+32 and you get 64.

What is the value of x?<br> 3/5x – 1/3 x = x – 1
Aleks04 [339]
The first step to solving this is to multiply both sides of the equation by 15.
9x - 5x = 15x - 15
Collect all of the like terms on the left side of the equals sign.
4x = 15x - 15
Move the variable to the left side of the equation and change its sign.
4x - 15x = -15
Now collect the like terms on the left side of the equation for the second time.
-11x = -15
Lastly,, divide both sides of the equation by -11 to get your final answer.
\frac{15}{11}
This means that the correct answer to your question is \frac{15}{11},, or 1\frac{4}{11} simplified.

Step-by-step explanation:

area of quadrilateral = sum of area of triangles

area of triangle ADC = .5 * b * h

= .5 * 12 * 5 = 30 km^2

area of ∆ABC = .5 * sinx* ab* ac

= .5 * sin 30 * 3* 13 = 39/4 = 9.75 km^2

area of quadrilateral = 39.75 km^2
