3 x 3/4= 9/4 or 2 1/4
7 x 3/8= 21/8 or 2 5/8
5 x 2/3= 7/3 or 2 1/3
4 x 1/5= 4/5
70 miles
Step-by-step explanation:
every two hours there are 70 miles. If that was the answer you were looking for anyways.
The communicative property means that multiplied numbers can be multiplied in any order.
3*2*4 is the same as 2*4*3. The answer will be the same.
So (24 * x) is the same as (x * 24).
Hope this helps! :)
Answer: -x
Apply Multiplicative Distribution Law:- 1/5 * 5x - 1/5 * 20 - 1/2 * 4x - 1/2 *(-8)
Determine the sign for multiplication or division: 1/5 * 5x - 1/5 * 20 - 1/2 * 4x + 1/2 * 8
Cross out the common factor: x - 1/5 * 20 - 1/2 * 4x + 1/2 * 8
Cross out the common factor: x - 4 - 1/2 * 4x + 1/2 * 8 - 4 - 2x + 1/2 * 8
Cross out the common factor: x - 4 - 2x + 1/2 * 8
Cross out the common factor: x - 4 - 2x + 4
Reorder and gather like terms: (x - 2x) + (- 4 + 4)
Collect coefficients for the like terms: (1 - 2) * x + (- 4 + 4)
Calculate the sum or difference : - x + (- 4 + 4)
The sum of two opposites equals 0: -x
