Answer:
3xy - xz, or x(3y - z)
Step-by-step explanation:
2x(y-z)+x(y+z) becomes
2xy - 2xz)+ xy + xz)
combining the xy terms, we get 3xy;
combining the xz terms, we get -xz
Thus, the complete simplified expression is 3xy - xz, or x(3y - z)
Hello!
1. To convert minutes to hours, we must multiply the number of minutes by 60, because that is how many minutes there are in an hour.
2. 1 pint = 16 ounces
16 × 8 = 128
Fernando bought 128 fluid ounces of milk.
3. 1 quart = 0.25 gallons
0.25 × 8 = 2
2 gallons are equivalent to 8 quarts.
4. Because when you divide 25 by 8, the result is greater than 3.
5. By dividing 6,400 by 2,000, because that is how you will find the exact equivalent of 6,400 pounds in tons.
7. 1 pound = 16 ounces
16 × 80 = 1,280
1,280 ounces is equivalent to 80 pounds.
9.
The missing value in the table is 918, because:
1 yard = 3 feet
3 × 306 = 918
306 yards = 918 feet
Answer: The correct answer is option (C); 25 feet
Step-by-step explanation: The standard of conversion between feet and yards is given as;
3 feet = 1 yard.
In other words, in every yard you will find times 3 feet. So in a spool of twine that contains four and two-thirds (4 2/3) yards of twine, conversion to feet would be given as;
X feet = (4 2/3) x 3
X feet = (14/3) x 3
X feet = 14
For the second spool the measurement is 11 feet of twine, so the total measurement would be derived as,
Spool 1 + Spool 2 = Total
14 + 11 = Total
25 = Total
Hence, the total measurement of twine would be 25 ft.
