Just think of it as you need some number multiplied by five to get 100.
I hope this helps. :)
Answer:
x = 95
Therefore the solution is 95
Step-by-step explanation:
<u><em>What is the solution to log Subscript 5 Baseline (x + 30) = 3</em></u>
<u><em /></u>
log₅(x+30) = 3
From our law of logarithm
5³ = x + 30
(but 5³ = 5 ×5×5=125)
125 = x + 30
Subtract 30 from both-side of the equation to get the value of x
125 - 30 = x + 30 -30
95 = x
x = 95
Therefore the solution is 95
We can check the correctness of our answer
log₅(x+30)
=log₅(95+30)
=log₅125
=log₅5³ ( Note: log₅5=1)
=1×3
=3
Answer:
x = -3
Step-by-step explanation:
-22 = 5x - 7
-15 = 5x
x = -3
Answer: 1 gallon
Step-by-step explanation:
Hi there!
Using the equation (12*18)-(7*3), where 12*18 is the area of the wall, 7*3 is the area of the door not being painted, you are left with 196 square ft. of wall. further dividing 196/200 is 0.98, meaning that Mr. Smith will only need one gallon of paint for his wall.
[(12*18)-(7*3)]/200
(215-21)/200
196/200
0.98
Your answer is probably:
22
