Answer:
1.4650 (the first option in the list of possible answers)
Step-by-step explanation:
Start by isolating the exponential expression on one side of the equal sign, thus subtracting 2 from both sides:
Now, in order to solve for "x", we need to lower the exponent, and for that purpose we use logarithm base "3":
In order to find this logarithm, we use the change of base formula:
which rounded to four decimals gives: 1.4650
7.2 miles per hour hope that helps if not then tell me. what is the unit or items. example:miles over hour.
Answer:
44
Step-by-step explanation:
use the order of operations
5 (3) 2 + 3 + 11. solve within parenthesis
15 × 2 + 3 + 11. multiply left to right
30 + 3 + 11. multiply left to right
33 + 11. add left to right
44. add
the order of operations is more commonly known as PEMDAS.
(parenthesis, exponents, multiply and divide, add and subtract)
If you are still confused there is a Brain Pop about PEMDAS. just search "order of operations" on the brain pop website
i think its b correct me if im wrong
294/X= -14
Cross multiply
294= -14X
Divide both sides by -14
294 : -14 = -21
-14 gets cancelled out so the X is isolated
X= -21 or -21=X it doesn’t really matter which way you put it
