Answer:
(a) The system of the equations 
has no solution.
(b) The system of the equations 
has many solutions 
Step-by-step explanation:
(a) To find the solutions of the following system of equations you must:
Multiply 
by 2:
Subtract the equations
0 = -3 is false, therefore the system of the equations has no solution.
(b) To find the solutions of the system you must:
Isolate x for 
Substitute into the second equation
The system has many solutions.
Isolate y for
Answer:
Draw a C plane and plot the dots if the coordinates
72% as a decimal is 0.72.
72% as a fraction is 72/100 = 18/25.
Answer:
x = 20
Step-by-step explanation:
Since there's 2 lines intercepting each other, the angle opposite of the other is the same.
3(20) + 50 = 110
6(20) - 10 = 110
Answer:
5 pieces
Step-by-step explanation:
To find the number of pieces divide 1 7/8 by 3/8
Change 1 7/8 to an improper fraction
substitute this value into the equation
to solve this complex fraction remove the bottom fraction by multiplying both the top and bottom fractions by the inverse of the bottom fraction.
Multiplying by the inverse results in a product of 1 so the result is
dividing by 1 gives just the top fraction.
Dividing out common factors leaves
