The quotient is 284 divided by 5, or
284
----- If you mult. numerator and denominator by 2, you get 578/10, or 57.8.
5
Try the numbers 550 and 600 (because 574 is between them). Now divide 550 and 600 by 10; the results will be 55 and 60. The actual value of 284/5 is between 55 and 60: 57.8 (which you can verify with a calculator).
So ur given the equation 1.44x=4.32
So you have to find x and you do this with algebra
X=4.32/1.44
X=3
So Emily bought 3 notebooks
Answer:
The answer is 86.08, hope this helps.
Step-by-step explanation:
The answer is -6. Thought there is a chance I am wrong. Need an explanation?
Recall that
d/dx sech(x) = - sech(x) tanh(x)
d/dx tan⁻¹(x) = 1/(1 + x²)
Then by the chain rule,
dy/dx = - sech(x) tanh(x) / (1 + x²)
