Rewrite the original equation as:
Log(4x^2) - log(3yz)
Rewrite log(4x^2) as log(4) + log(x^2)
Rewrite log(4) as 2log(2)
Rewrite log(x^2) as 2log(x)
Separate log(3yz) into 3 logs: log(3), log(y) and log(z)
Now combine them to get:
2log(2) + 2log(x) - log(3) - log(y) - log(z)

Answer:
44°
Step-by-step explanation:
The sum of the marked angles on the right is equal to the sum of the marked angles on the left:
? + 74 = 92 + 26
? = 92 +26 -74 = 44
The missing angle is 44°.
_____
<em>Additional comment</em>
The vertical angles in the center of the figure are v = 62°, the measure required to bring the total to 180° in each triangle. We have shortcut the equation(s) ...
? + 74 + v = 180 = 92 + 26 + v
by subtracting v from both sides, giving ...
? +74 = 92 +26
Lets use elimination to solve the system of equations. We do this by adding the two equations terms together.
a + b = 5
a - b = 3
(a + a) + (b + (- b)) = (3 + 5)
2a + 0 = 8
We can then solve this new equation for a.
2a = 8
a = 4
After this, we can plug in the value of a into one of the equations and solve for b.
a + b = 5
4 + b = 5
b = 1
You're correct, the answer is 1.
Answer:
12.54kg
Step-by-step explanation:
(23/4 + 35/6 + 23/8)kg
= 301/24
= 12.54kg
Answer:
-(-4)(-6)*3/5(10+15)
when there is a (-) in front of an expression in parentheses, change the sing of each term in the expression.
4*(-6)*3/5*(10+15)
Add the numbers (10+15)
4(-6)*3/5*25
multiplying an odd number of negative terms makes the product negative
-4*6*3/5*25
reduce the number with the greatest common factor 5
-4*6*3*5
calculate the product
solution
-360
