The lines are perpendicular to each other because -8 and 1/8 are opposite reciprocal of each other. <span />
The answer is A . 7.53 , -0.53
Percentage left = 100-(12+25) = 63%
63% = (60+210+108)
63% = 378
1% = 378/63 = 6
no. of students biking = 25% * 6
= 150 students
<h2>
The value of A + b + c = - 9</h2>
Step-by-step explanation:
We have,
A + b + c and
A = 4, b = - 5 and c = - 8
To find, the value of A + b + c = ?
∴ A + b + c
Put A = 4, b = - 5 and c = - 8, we get
= 4 + ( - 5) + ( - 8)
= 4 - 5 - 8
= 4 - (5 + 8)
= 4 - (13)
= 4 - 13
= - 9
∴ The value of A + b + c = - 9
