First you should Simplify
\frac{20}{24} = \frac{5}{6}
\frac{3}{6} + \frac{1}{3} = \frac{5}{6}


Solution
1. Find the LCM between 6 and 3 which is 8
2. Times 3 and 6 to both sides of the equation respectively.
\frac{3 \times 3}{18} + \frac{6 \times 1}{18}
\frac{9 + 6}{18} = \frac{15}{18}
3. Simplify the answer by dividing by 3.

loris [4]

Answer:

The displacement is: - 80 i

Step-by-step explanation:

In order to answer the question, you have to apply the displacement formula, which is:

ΔX= Xf-Xi

Where ΔX is the displacement, Xf is the final position and Xi is the initial position. The formula represents the change in the position of an object from the origin.

Let the origin be in 0 km,with the x-axis positive to te right.

Notice that the displacement is a vector. The positions are:

Xf=163 km (i)

Xi= 243 km (i)

Because John starts in 243 km and finishes in 163 km.

Where i is the unit vector in the x direction.

Therefore:

ΔX= 163 i - 243 i

Solving:

ΔX= -80 i

Notice that for calculating the displacement you just need the initial and final position. It doesn't depend on the distance traveled.

What is the volume of a rectangular prism length 12ft height 14ft width 17ft
NeTakaya
Answer:  <span>2,856 ft³ .</span>
_____________________
Volume of a rectangle prism = BASE AREA * height ;

The "base area" is the area of the rectangle:

(Area = length  width; or, "L * w").
_______________________________________________
So, volume of a rectangular prism = L * w * h  ;  h = height ;
_________________________________________
  V = L * w * h  = 12 ft * 17 ft. * 14 ft =  2,856 ft³

love history [14]
Let's use q to represent the number of quarts needed.

you would have the following:

2q= 107-19
2q=88
q=44
44 is the number of quarts in a in the barn.
Now you have to divide that number by 4 to get gallons because there is 4 quarts in a gallon.
There are 11 gallons of paint.
