Answer: the cost would be the same for 12 shirts.
Step-by-step explanation:
Let x represent the number of shirts for which the cost would be the same.
One company charges $9.65 per shirt plus a setup fee of $43. This means that total amount charged for x shirts would be
9.65x + 43
Another company charges $8.40 per shirt plus a $58 fee. This means that total amount charged for x shirts would be
8.4x + 58
For both costs to be the same, the number of shirts would be
9.65x + 43 = 8.4x + 58
9.65x - 8.4x = 58 - 43
1.25x = 15
x = 15/1.25 = 12
Answer:
x = 2
Step-by-step explanation:
10x - 14 = 7x - 8
3x - 14 = -8
3x = 6
x = 2
Hope this helps!
Answer: B
Step-by-step explanation: to find the mean you add all of the values and divide it by the number of values you added. so it would be (13+14+14+14+14+14+15+15+15+15+15+15+16+16+17)/15 which equals 14.8
Real positive numbers are decimal numbers, not limited to integers, which are above zero.
For this case we have the following system of equations:
Rewriting we have:
Adding equations we have:
Clearing x:
Then, we look for the value of y:
Answer:
The solution to the system of equations is:
x = -89.5
y = 101.5
