$48

Step-by-step explanation:

Ashton is saving money for a new bike. He needs 120$ But only has saved 60% so far. How much more money does he need to buy the scooter

Ashton needs money for new bike=120$

savings of ashton is 60 % of his bike cost

hence 60% of 120 dollar will be

His saving=(60/100)*120=7200/100=72$

remaining cost will be obtained by subtracting saved money from total cost

total cost=120 dollar

saved money=72dollar

hence

Remaining more money he needed is =120-72=48$

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

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
