Answer:
10.5
Step-by-step explanation:
63/6=10.5 or 10 and 1 half
Answer:
$1745
$3485
Step-by-step explanation:
First month = $150
Consequently, 5 dollars less. Therefore in the remaining months;
(150-5) x 11months
= 145 x 11
= $1595
Therefore to get the total membership in a year we add up 150 and 1595
Total membership in a year = $1745
In year 2, he will be paying 145 dollars in the entire year
(12 x 145) = 1740
So the total membership in 2 years = $1745+$1740
= $3485
Answer:
a) one solution
b) no solution
Step-by-step explanation:
Systems of equations can be described as having one solution, no solution or infinite solutions:
One solution: 'x' and 'y' are equal to only one value
No solution: 'x' and 'y' can not be solved with the given equations
Infinite solutions: values for 'x' and 'y' include all real numbers
In order to evaluate the systems, putting them in the same format is your first step:
a) - y = -5x - 6 or y - 5x = 6
y - 5x = -6
Since both equations have the same expression 'y - 5x', but there are equal to opposite values, this system would have no solution, as this would not be possible to calculate.
b) y + 3x = -1
y = 3x -1 or y - 3x = -1
Solving for 'y' by adding the equations and eliminating 'x', gives us:
2y = -2 or y = -1
Using y = -1 to plug back into an equation and solve for 'x': -1 + 3x = -1 or x = 0. Since 'x' and 'y' can be solved for a value, the system has just one solution.
Treat this as an ordinary linear equation. Try to isolate x, as some value. Also remember the basic rules of inequalities: If you're dividing, or multiplying, by a negative, you flip the inequality.
