Answer:
x = 4.25
Step-by-step explanation:
The given equation of line is :
4(2x-5)+6=-3(-4x+8)-7
Solving LHS,
4(2x-5)+6 = 8x-20+6
= 8x-14
Solving RHS,
-3(-4x+8)-7 = 12x-24-7
= 12x-31
So,
8x-14 = 12x-31
Taking like terms together,
8x-12x = -31+14
-4x = -17
x = 4.25
So, the value of x is equal to 4.25.
Answer:
R = 56.6 ohms
Step-by-step explanation:
Given that,
The voltage of the battery, V = 1.7 volt
We need to find the resistance in the circuit if it uses a current of 0.03 A.
Let the resistance be R. It can be solved using Ohms law as follows :
V = IR

So, the resistance in the circuit is 56.6 ohms.
