Answer:
Lithium
Explanation:
Lithium batteries features primary cell construction.They are single-use or non rechargeable batteries
Answer:
Step-by-step explanation:
- Since y = -1, we will substitute the y variable in the equation for -1.
-1 = -5/2x + 4
- Take away 4 from both sides in order to find out what x equals so we can substitute it.
5 = -5/2x
- turn it into a positive by multiplying each side by -1.
-1(-5 = -5/2x) =
5 = 5/2x
- Divide each side by 5.
1 = 1/2x
- Multiple both sides by 2.
2 = x
- Substitute the variables.
x = 2
y = -1
-1 = -5/2(2) + 4
Let the number of article be x,
let the machine required be y
x/42=63
x/y=54
x=63*42
x=54*y
∴42×63=54y
y=49
