The value of the x if e3*6 - 87 equals e3x - 81
We can turn 150% into a decimal by moving our decimal point two places to the left, or 1.5. We then multiply 1.5 with 60 as the word "of" in math automatically tells us to do that.
We have our answer of 90.
Answer:
The traveller's speed is 5ft/s and the walkway speed is 3ft/s
Step-by-step explanation:
Given
Represent the traveller's speed with T and the walkway's speed with W.
When the traveller walk against the walkway, we have:
---- i.e. 2ft/s against the walkway
When the traveller walk with the walkway, we have:
---- i.e. 8ft/s with the walkway
Required
Solve for W and T
--- (i)
--- (ii)
Add (i) and (ii)



Divide both sides by 2



Substitute 5 for T in (ii)


Make W the subject


Hence, the traveller's speed is 5ft/s and the walkway speed is 3ft/s
X=6 because -3*6= -18 then take the absolute value of that which is 18
