Answer:
The mistake she made was ; She didn't change the sign when subtracting -3/4 from both sides
She wrote 5/4+3/4 instead of 5/4-3/4
Step-by-step explanation:
Correct solution:
Subtract-3/4 from both sides
Simplify
Answer:
X= 10m
Step-by-step explanation:
Assume that x is the length
(24.5/100)*x = 2.45 m (2m 45cm = 2.45m)
x = (2.45 * 100)/24.5
x = 10m

Answer:
D(4, 1)
Step-by-step explanation:
The two diagonals have the same midpoint, so ...
(A+C)/2 = (B+D)/2
A+C = B+D . . . . multiply by 2
A+C-B = D . . . . . subtract B
D = (1, 1) + (5, 3) - (2, 3) = (1+5-2, 1+3-3)
D = (4, 1)
Answer:
So the expression in simplified radical form will be
Step-by-step explanation:
We have have given the expression
We have to write this expression in simplest radical form
For writing in simplest radical form we have to rationalize first
So after rationalizing
So the expression in simplified radical form will be
