Answer:
145
Step-by-step explanation:
angles in a pentagon add up to equal 540
Hence, 110 + 90 + 80 + 115 + v = 540
( note that we just created an equation that we can use to solve for v )
We now solve for v using the equation created
110 + 90 + 80 + 115 + v = 540
step 1 combine like terms
110 + 90 + 80 + 115 = 395
we now have 395 + v = 540
step 2 subtract 395 from each side
540 - 395 = 145
395 - 395 cancels out
we're left with v = 145
You said ax + 3b = 2f
Subtract 3b from each side: ax = 2f - 3b
Divide each side by 'a' : x = (2f - 3b) / a
I believe the answer is 6 but i’m not for sure
Answer:
yes because any input of time results in only one output of altitude
yes because the airplane increases and decreases in altitude at the same rate
pick either one :>
Equations can have one solution, but inequalities have infinite solutions.
Hope this helps!
