Which number line correctly shows 1.5 + 2.5? A number line going from 0 to 6.5 in increments of 0.5. An arrow goes from 0 to 1.5 and from 1.5 to 4. A number line going from 0 to 6.5 in increments of 0.5. An arrow goes from 0 to 1.5 and from 1.5 to 3. A number line going from 0 to 6.5 in increments of 0.5. An arrow goes from 0 to 2.5 and from 2.5 to 5. A number line going from 0 to 6.5 in increments of 0.5. An arrow goes from 1.5 to 3 and from 3 to 5.5.

i can't solve unless i know what the line is

step-by-step explanation:

welcome to/p>

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

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
