Answer: -1mn + 10m +5n
Step-by-step explanation:
14 - 15 = -1
-12 + 22 = 10
7 - 2 = 5

2/3 as well because you use perimeter to find area
Answer:
5.5 meters above start position.
Step-by-step explanation:
-Let X be the start position.
#Total distance below the start position is calculated as:
#Total distance above the start position X:
#Distance above/below start position is:
Hence, The vessel is 5.5 meters above the start position
Answer:
7
Step-by-step explanation:
we use Pythagorean theorem for solving x
a^2 + b^2 = c^2
c^2 - a^2 = b^2
(√58)^2 - (3)^2 = b^2
58 - 9 = b^2
49 = b^2
b = 7
Answer:
y= 28/17
x= 57/17
Step-by-step explanation:
5x + 2y = 22
-2x + 6y = 3
(2)(5x + 2y = 22)→ 10x + 4y = 44
(5)(-2x + 6y = 3)→ -10x +30y = 15
Add this last eq → 34y=56 → y= 28/17
Replace this in any equation
-2x + 6(28/17) = 3 → x= - (54/17-168/17)/2 = 57/17
