a=6.1
He messed up step 2 he added instead of multiplying
Answer:
B. (-1,7)
C. (0,5)
D. (2,3)
Step-by-step explanation:
We solve this question looking at the graphic.
A. (-7, 1)
When
, and thus (7,-1) is not solution of the equation.
B. (-1,7)
When
, and thus (-1,7) is a solution of the equation.
C. (0,5)
When
, and thus (0,5) is a solution of the equation.
D. (2,3)
When
, and thus (2,3) is a solution of the equation.
E. (3, 2)
When
, and thus (3,2) is not part of the solution
F. (5,0)
When
, and thus (5,0) is not part of the solution
Answer:
37/5
Step-by-step explanation:
7 2/5 = 37/5
5x7=35
35+2=37
Multiply the whole number and denominator then, add the numerator and put the sum of that back ontop of the denominator
Example:
W N/D DxW=X X+N= Y
W N/D = Y/D
