Tyler made bracelets. he made a total of 235 bracelets. on monday he made 23, on tuesday he made 78, and on wednesday he made 54. how many did he make on thursday?

Tyler made 80 bracelets on Thursday

Step-by-step explanation:

Tyler made

23 bracelets on monday

78 bracelets on Tuesday

54 bracelets on Wednesday

T bracelets on Thursday ( let number of bracelets made on Thursday be T)

Total number of bracelets made by Tyler = 235 = sum of bracelets made on Monday, Tuesday, Wednesday and Thursday

235 =23+78+54+T

235= 155+T

T = 235-155

=80

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

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
