Answer:

Step-by-step explanation:
Considering the function:

The independent variable is "x" and we are asked to model it in terms of the variable "y":

Then, in order to solve for x (which resides in the exponent), we need to use the logarithm function.
Since the base of the exponent is 1.5, we need to use the logarithm base 1.5, to lower that exponent "x":

Answer:
Step-by-step explanation:
2x+90=7x
2x=7x-90
2x-7x=-90
-5x+-90
x=18
Answer:
x=66
Step-by-step explanation:
118+106+70+x=360 The total sum of degrees in a quadrilateral is 360.
294+x=360 Add the given angle measures together.
x=66 Subtract 294 from both sides.
