Step-by-step explanation:
Given:

To Find:
x = ?
Solution:
We know Logarithmic identity as

.............Given
Taking Log on both the side we have

The Solution to the equation 4ˣ = 9.2 is the option D ) x = 1.60
-52 is the answer because you have to isolate 1/3x by adding 2/3 to -18 then you have to multiply -18/1 by 3 so you can have a common denominator. After, you should have -54/3 plus 2/3 you subtract the two and get -52/3. You then have 1/3x equals -52/3. You divide 1/3x by -52/3 which means you have to multiply by the reciprocal of 1/3x which is 3/1x. You multiply that by -52/3. The threes cancel out and you're left with x = -52.
Answer:
x = 16
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent, that is
∠ B = ∠ E , substitute values
x + 15 = 6x - 65 ( subtract 6x from both sides )
- 5x + 15 = - 65 ( subtract 15 from both sides )
- 5x = - 80 ( divide both sides by - 5 )
x = 16
Answer:
$(3b+2)
Step-by-step explanation:
The cost of making b bracelets = 4+5b
The cost of making b necklaces = 8b+6.
To determine how much more it cost to make b necklaces than b bracelets, we simply subtract.
Extra Cost = Cost of b Necklaces-Cost of b Bracelets
=(8b+6)-(4+5b)
open the brackets
=8b+6-4-5b
Collect like terms
=8b-5b+6-4
=3b+2
It costs $(3b+2) more to make b necklaces than b bracelets.
