Answer:
26-10a
Step-by-step explanation:
Question : 23 - 7a + - (3a - 3)
1. Remove the parenthesis - When there is a "-" in front of the parenthesis, change the sign of each term in parenthesis
23-7a-3a+3
2. Add the numbers that you have - 23 and 3
23 - 7a - 3a + 3 ------
26-7a-3a
3. Collect the like terms - 7a and 3a
26 - 7a - 3a
26 - 10a
Your simplified answer is 26 - 10a
Answer:
1)you find the least prime factors of each number
2)Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1
Do 168/2=84 meaning the time is doubled so its takes 12 mins to rotate 168 times.
Refer to the figure shown below.
Quadrilaterals ABCD and EFGH are similar.
The shortest side (the 4th side) of quadrilateral ABCD is AD = x.
The three longest sides are
AB = 24, BC = 16 and CD = 12 feet.
The corresponding shortest sides of quadrilateral EFGH are
EH = 9, and GH = 18 feet.
Because the two quadrilaterals are similar, therefore
![\frac{AB}{EF}= \frac{AD}{EH} \\ \\ \frac{x}{9} = \frac{12}{18} \\ \\ x= \frac{9 \times 12}{18} =6](https://tex.z-dn.net/?f=%20%5Cfrac%7BAB%7D%7BEF%7D%3D%20%5Cfrac%7BAD%7D%7BEH%7D%20%5C%5C%20%5C%5C%20%5Cfrac%7Bx%7D%7B9%7D%20%3D%20%5Cfrac%7B12%7D%7B18%7D%20%5C%5C%20%5C%5C%20x%3D%20%5Cfrac%7B9%20%5Ctimes%2012%7D%7B18%7D%20%3D6)
Answer: The length of the 4th side of quad ABCD is 6 feet.
1/3a - 5 - (1/6a + 3)
= 1/3a - 5 - 1/6a - 3
= 1/6a - 8 Answer
