65 is the answer. m = slope = delta y / delta x
delta y = 520 - 325
delta x = 8 - 5
Be well.
Answer:
0.222
Step-by-step explanation:
There is no solution ,<span>a+c=-10;b-c=15;a-2b+c=-5 </span>No solution System of Linear Equations entered : [1] 2a+c=-10
[2] b-c=15
[3] a-2b+c=-5
Equations Simplified or Rearranged :<span><span> [1] 2a + c = -10
</span><span> [2] - c + b = 15
</span><span> [3] a + c - 2b = -5
</span></span>Solve by Substitution :
// Solve equation [3] for the variable c
<span> [3] c = -a + 2b - 5
</span>
// Plug this in for variable c in equation [1]
<span><span> [1] 2a + (-a +2?-5) = -10
</span><span> [1] a = -5
</span></span>
// Plug this in for variable c in equation [2]
<span><span> [2] - (-? +2b-5) + b = 15
</span><span> [2] - b = 10
</span></span>
// Solve equation [2] for the variable ?
<span> [2] ? = b + 10
</span>
// Plug this in for variable ? in equation [1]
<span><span> [1] (? +10) = -5
</span><span> [1] 0 = -15 => NO solution
</span></span><span>No solution</span>
Answer:
breadth = 8, length = 32
Step-by-step explanation:
perimeter = 2 x (length x breadth)
= 2 x ((24 + b) + b))
= 2 x (24 + 2b)
= 48 + 4 b
48 + 4b meters costs rupees 2400
each meter costs rupees 30
so,
30 x (48 + 4b) = 2400
1440 + 120b = 2400
120b = 960
b = 8
the breadth is 8m, the length is 8 + 24 = 32m
