Answer:
Step-by-step explanation:
A linear expression has the highest power of the variable to 1, i.e ax+b
Then only the first option is in a linear expression format
9x-2
Answer:
Step-by-step explanation:
Given
Required
True values of x
We have:
Collect like terms
Divide both sides by 3
This means that x has a value lesser than 14.67.
Hence, the valid values are:
40 ounces equal to 2.5 pounds. Let me know if this answers your question! :)
Answer:
a = 132; b = 12; c = 36
Step-by-step explanation:
a = b + 120
b = b
c = 3b
a + b + c = 180
(substitute these into the above equation)
b + 120 + b + 3b = 180
5b + 120 = 180
-120 -120
5b = 60
/5 /5
b = 12
(substitute b back into the first equations)
a = (12) + 120 = 132
b = (12)
c = 3(12) = 36
(check: 132 + 12 + 36 = 180)
