Answer:
15y
Step-by-step explanation:
first the 2 can cancel:
turns into:
now since we need to find x-y,
x=16y
16y-y=15y
I might come back to this because I'm not 100% sure this is the answer you are looking for. Let me know if you have any questions.
Answer:
x equals 3.00cm
Step-by-step explanation:
Use Pythagoras' Theorem.
a = (14x-45)
b = (16x+27)
c = (25x)
Plug in the variables above into Pythagoras' Theorem that is, a^2+b^2=c^2.
Solve the resulting quadratic equation and reject the negative answer as length is always positive.
70-3·6+9
Remember PEMDAS.
You must multiply the 3 and 6 together, and you would get 18.
Then, you subtract 18 from 70, which would give you 52.
And finally, you would add 9 to 52, getting 61 as your final answer.
