5 1/3 + x = 2 1/2. Use least common denominator or easiest common denominator. Please work out

julia-pushkina [17]

Answer:

The answer is x = -17/6.

Step-by-step explanation:

Given:

5 1/3 + x = 2 1/2 . Using least common denominator.

Now, to solve the equation:

$5\frac{1}{3}+x=2\frac{1}{2}$

$=\frac{16}{3} +x=\frac{5}{2}$

Subtracting both sides from 16/3 we get:

$x=\frac{5}{2}- \frac{16}{3}$

Now, the least common denominator of 2 and 3 is 6.

So, we using this we calculate:

$x=\frac{5\times 3-16\times 2}{6}$

$x=\frac{15-32}{6}$

$x=\frac{-17}{6}$

Therefore, the answer is x = -17/6.

On a coordinate grid, your campsite is located at (3, – 5), and the next checkpoint station is located at (–10, 1). Each unit in

Answer: <span>A. about 30.8 miles
</span><span>
The x and y distance from the campsite at A (3, – 5), and the next checkpoint station is located at B (–10, 1) would be:
Xab= Xb- Xa= -10 - 3= -13
Yab= Yb- Ya= 1- (-5)= 6

The resultant distance would be
c^2= a^2+b^2
c^2= (-13)^2 + (6)^2
c= </span>√(169+36)= √205
c=14.32

If each unit in the coordinate plane represents 2.15 miles, the true distance= 14.32*2.15 miles= 30.78 miles
