Help please and thank you

x=7

Step-by-step explanation:

You know that the 17x+11 and 19x-3 are equal because they are corresponding angles. Then, you would solve it like an algebraic equation:

17x+11 = 19x-3

Move all the like terms onto one side.

14=2x

It would be easier to look at if moved the x onto the left so it would look like this:

2x = 14.

Then divide by 2 and your answer should be 7.

answer: 193

explanation:

200-7 = 193

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
