Answer:
Step-by-step explanation:
Let the number be x
5 times a number = 5x
24 - 5x = 15
-5x = 15-24
-5x = -9
x= -9/-5
x = 9/5
or x = 1.8
Answer:
8
Step-by-step explanation:
First do whats in the parenthesis:
(8+18/9)
Using PEMDAS again, we do the division first:
(8+2)
Now addition:
(10)
Now subtraction:
(10)-2
8
Answer:
G=m/r-h^2
Step-by-step explanation:
move all the terms to the left side and set equal to zero. Then set each factor equal to zero. Hope this helps!
Without calculating we can say that the system with the original cost $60 ( the cheaper system ) had a greater percent decrease.
This is because $10 is a greater percentage of $60 than it is of $90 ( if we calculate it is 16.66% in the first case and 11.11% in the second case).
Answer:
0.5amps
Step-by-step explanation:
I is inversely proportional to resistance
I = k/R
k = I/ R
k = 20/5
k = 4
This means that, I = 4/R
So, when R = 8ohms,
I = 4/8
=0.5amps
