Answer:
b
Step-by-step explanation:
The sum of angles in a triangle is 180°. Therefore,
x - 11 + 48 + 90 = 180
x + 127 = 180
x = 53°
Answer:
(5/4-3/4)
divide both sides by -7 then line them up and solve the equation and delete one variable.
Answer:
The error is in step 3. You cannot use a property of logarithms to prove that same property.
Step-by-step explanation:
Here we the proof of the quotient rule as
If Logₐx = M and Logₐy = N
Then x =
and y = 
x ÷ y =
÷
= 
Take log of both sides we get
Logₐ(x÷y) = Logₐ
Logₐ(x÷y) =M-N logₐa
Logₐ(x÷y) =M-N
∴Logₐ(x÷y) = Logₐx - Logₐy
Answer:
$52 to $45
Step-by-step explanation:
First put their income into a ratio:
520 to 450
Now you can put it into a fraction and then simplify it:
520/450
Divide each by 10
520/10 = 52
450/10 = 45
So 52/45
