Answer:
No, Angela is not correct.
As the method Jim was performing will also lead to the solution.
Step-by-step explanation:
We are given first equation as:
Ax + By = C
Second equation is:
Dx + Ey = F
Jim solved the equation as:
He begins by multiplying equation (1) by D and equation (2) by A.
and so by subtracting both the equations he will obtain a value of y.
and then put the y-value in any of the given two equations to obtain the value of x.
Angela Method:
you should have multiplied equation (1) by E and equation (2) by B.
and when she will subtract both the equations she will get the value of x first and then when she will put the value of x in any of the given equation she will obtain the value of y.
But both will get a value for x and y.
Hence, the method Jim was performing was also correct.
The decrease is (95-68) = 27 .
As a fraction, the decrease is 27/95 of the original amount.
To change any fraction to a decimal, do the division:
(27) divided by (95) = 0.2842...
To change any decimal to a percentage, move the
decimal point two places that ==> way:
0.2842... = 28.42... %Answer:
Step-by-step explanation:
The answer is 3.34 pounds also the estimate would be 3 pounds.
we use divsion, 10 divided by 5 is 2, everyone get 2 yumy cupcakes.
Considering that the given derivative is:
dy
----- = (x - 6)^ (1/2) ,
dx
y is the function whose derivative is (x - 6)^ (1/2).
Given that the derivative of (x - 6) ^ (3/2) is (3/2)* (x - 6)^ (1/2), you have that the function searched is y = (2/3) ( x - 6) ^ (3/2) plus a constant.
You can prove that dy / dx is (2/3)*(3/2) (x - 6) ^ (3/2) = (x - 6)^ (1/2).
Answer: y = (2/3) (x - 6)^(3/2).+ constant
