Answer:
Step-by-step explanation:
- 7 + 3x - 12x = 3x + 1
- 7 - 9x = 3x + 1
- 3x + 9x = 7 - 1
- 12x = 6
- x = 6/12
- x = 1/2
It has one solution
13/52= 1/4 or .25
If you have a scientific calculator it really helps with simplifying numbers to the lowest term.
Answer:
8.06
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(6 - 2)² + (0 - 7)²
√(4)² + (-7)²
√(16) + (49)
√65
= 8.06
Answer:
$=19400
Step-by-step explanation:
Average prices= $18,500
Number of prices that were quoted= 7
Expected sum that produces this mean= 7*18,500=$129,500
Sum of quoted prices=
$(15,500+ 18,800+ 16,900+ 19,900+18,000+21,000) =$110100
Next price to be quoted will be ;
$129,500-$110,100
$=19400
