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.
Answer:
PEMDAS!!! (Parentheses, exponents, multiplication, division, addition, subtraction)
Step-by-step explanation:
Parentheses first!
50-35=15
Then subtraction!
80-15=65
Hope this helped!!! :)
Divide the width by 2, as that is your scale.
26 / 2 = 13
The house would be 13 inches long.
