Answer: 2x + y
<u>Step-by-step explanation:</u>
logₐ(3) = x
logₐ(5) = y
logₐ(45) = logₐ(3²· 5)
= logₐ(3)² + logₐ(5)
= 2 logₐ(3) + logₐ(5)
= 2 x + y <em>substituted given values (stated above)</em>
Answer:
x= - AB-4/5 and No Solution
False for all xER
Step-by-step explanation:
Answer:
sister = 6 years
John=18 years
Step-by-step explanation:
A(S) + 12 = 3 * A(S), subtracting A(S) from both sides one gets 12 = 2 * A(S). Now dividing both sides by 2 we get A(S) = 12/2 = 6 . Therefore, the age of the sister is 6 years when her brother John is three times as old, that is 18 years.
0.15x + x <(or equal to) 50
Where x is the meal's cost (no tip included)
50 - 15% = 42.5.
x >(or equal to) 42.50.

The first thing thing you must do is create an equation for this problem. Remembering that 7.75% = 0.0775
($4,100 × 0.0775 + $4,100 ) + $600
Now, all you have to do is solve it. You will first have to start with the numbers in the parenthesis using the order of operation (PEMDAS).
P = Parenthesis
E = Exponent
M = Multiplication
D = Division
A = Addition
S = Subrtaction
$4,100 × 0.0775 + $4,100 ) + $600
$4,417. 75 + $4,100 + $600
$4,417. 75 + $600 = $5,017.75

I hope this helps! :)
