Answer:
2a + 2b + 6c.
Step-by-step explanation:
To find this we subtract :-
3a + 5b + 7c - (a + 3b + c)
= 3a + 5b + 7c - a - 3b - c Now combine like terms:
2a + 2b + 6c (answer).
Answer:No, because it has a constant rate of change.
Step-by-step explanation:
Answer: x < 3
Step-by-step explanation:
To solve this inequality, we will simplify and isolate the x variable.
Given:
5x - 4 < 2x + 5
Add 4 to both sides:
5x < 2x + 9
Subtract 2 from both sides:
3x< + 9
Divide both sides by 3:
x < 3
Answer:
-203
Step-by-step explanation:
(10−3)×(3−2^5
)
Subtract 3 from 10 to get 7.
7(3−2^5
)
Calculate 2 to the power of 5 and get 32.
7(3−32)
Subtract 32 from 3 to get −29.
7(−29)
Multiply 7 and −29 to get −203.
−203
Answer:
The student should have switched the direction of the inequality sign to
get –5 > x for a final answer.
Step-by-step explanation:
When multiplying or dividing an inequality by a negative "flip" the inequality sign
The student should have switched the direction of the inequality sign to
get –5 > x for a final answer.
---------------
Note:
For a more conventional appearance the entire inequality can be flipped to
–5 < x
