Answer:
Step-by-step explanation:
We are solving for 
in the equation:
First, isolate the variable term by subtracting 
from both sides of the equation:
Now, divide both sides of the equation by the coefficient of :
This solution for , as a decimal, would be non-terminating. If you divided 
into 
, you would get the non-terminating decimal of:
Therefore, our solution is:
-
We can check our solution by substituting 
for in the initial equation:
Substitute:
Simplify 
:
Add:
Since both sides of the equation are equal, our solution is correct!
Answer:
Step-by-step explanation:
Part 1
$6.84 + $4.88 + $8.32 + $4.98 = $25.02
The total cost of the steaks comes to $25.02.
Part 2
2 × 20 = 40
40 - 25.02 = 14.98
1.25 is 5% of 25.02
14.98 - 1.25 = 13.73
The family gets $13.73 back in change.
Part 3
6.84 ÷ 12 = 0.57
4.88 ÷ 8 = 0.61
8.32 ÷ 16 = 0.52
4.98 ÷ 6 = 0.83
Part 4
0.83 - 0.52 = 0.31
They should buy larger steaks to share because the larger steaks are $0.31 cheaper than the smaller steaks.
Answer:
a.) 13 students
b.) 53 members
Step-by-step explanation:
a.) In the given equation of y=4x+13, "x" represents how many years have gone by since the club had started. The number "13" in this equation represents the y-intercept, or the value of "y" when x = 0. Therefore, when "x" is 0 years, there were 13 students in the clubs, meaning that the original group that started the club contained 13 students.
b.) Since the question asks how many members that the club will have after their tenth year and you already know that "x" in the equation y=4x+13 represents the number of years since the club started, all you have to do is plug 10 in for "x" in the equation; so, the equation will now look like this: y=4(10)+13. Keeping PEMDAS in mind, you first multiply 4 and 10 to get 40, and then you add 13 to get an answer of 53 members after year 10.
