Answer:
+6 charge and −6 charge
Step-by-step explanation:
In this problem, we need to find two charges that have a sum of 0.
In option (d), both charges have the same magnitude. But they have opposite charges.
Sum means to add up charges i.e.
+6 charge +(-6) charge = 0 (they have opposite charges)
Hence, the correct option is (d).
You write it like 3 21/100
Answer:
A
Step-by-step explanation:
Substitue 15 into the x value and complete the equation.
This is because 2,280 is the original distance. 15 would be the hours and 60 would be how many miles per hour. So we multiply 15 and 60 and get 900, this is how many total miles they have driven. But when we subtract that number from 2,280, and we get 1,380, this is how many miles they have left.
Answer:
7x +2y =24 --------- (i)
8x +2y= 30 ---------(ii)
Subtracting eqn. (i) & (ii)
7x +2y =24
8x +2y= 30
- - -
___________
-x = - 6
Putting the value of x in eqn. (i)
7*6 +2y =24
42 +2y =24
2y =-18
y = - 9
Hence, x=6 and y= - 9
