Answer:
x = -12
Step-by-step explanation:
Set logs up on both sides-
log 16^x = log 64^x+4
The variable goes behind because of the exponent log <em>property</em> (exponents are permitted to go behind the log to multiply)-
x * log 16 = x + 4 * log 64
Divide both logs out-
log 64/log 16 = 1.5
Simplify-
x = x+4(1.5)
1.5x + 6 = x
Remove 1.5-
1 - 1.5 = -.5x
Simplify-
-.5x = 6
Divide both sides-
6/-.5x = -12
Hence, the answer would be -12
Answer:
commutative property of multiplication
Step-by-step explanation:
The value of the product of the given equation remain the same while the order is reversed
The number sequence 4 × 6 = 6 × 4 is an example of the commutative property of multiplication
Reason:
The given number sentence is 4 × 6 = 6 × 4
Required: The property the number sentence is an example of (represent)
Solution:
The difference between the left and right expression is that the order of the
values being multiplied is changed or reversed (commute)
Therefore, the number sentence states that the value of the multiplication
of two variables remain equal when the places of variables are
interchanged as follows; a × b = b × a
a × b = b × a is an example of commutative property of multiplication
Therefore;
4 × 6 = 6 × 4 is an example of the commutative property of multiplication
Answer:
90 calories in a banana.
Step-by-step explanation:
O = B - 20 where O is the number calories in an orange and B is a that in banana.
Also 7B = 9O
From the above O = 7B / 9 so substituting in the first equation:
7B / 9 = B - 20
7B = 9B - 180
2B = 180
B = 90.
