2(3x−4)=5x(6)
Simplify both sides of the equation.
2(3x−4)=5x(6))
(2)(3x)+(2)(−4)=5x(6)(Distribute)
6x+−8=30x
6x−8=30x
Subtract 30x from both sides.
6x−8−30x=30x−30x
−24x−8=0
Add 8 to both sides.
−24x−8+8=0+8
−24x=8
Divide both sides by -24.
−24x/−24 = 8/−24
x=−13
Answer:
percentage decrease is 70%
Step-by-step explanation:
To find percentage decrease of 2 quantities, we have to find the difference of the quantities and divide by the original quanity. Then we multiply by 100 to find the PERCENTAGE.
We will use formula:
Where
"New" is the latest quantity
"Old" is the first (previous) quantity
Here, New = 5.3 & Old = 17.71
We substitute into formula and find:
So we can say that the percentage decrease is 70%
log(b,N) = x converts to b^x = N. The base of the log is the base of the exponent. The exponent term is on its own side in the original log equation.
Answer: b^x = N
