Tim answered all the questions on his math test but got 10 answers wrong. He received 4 points for every correct answer, and the
charle [14.2K]
4x = 76
Where x is how many awnsers he got correct and 4 how many points each correct question awnsered.

Now you just have to isolate x by dividing both sides of the equation by 4

4x/4 = 76/4
x = 19

So he got 19 questions right and 10 awnsers wrong. In total there were 29 questions on his test

What is the sum of the finite arithmetic series (-5)+0+5+10+ ......+65
Alex17521 [72]

If you want to solve this problem using formulas, there are two important formulas:

t1  =  first term  =  -5          

tn  =  nth term  =  last term  =  -5

n  =  numbr of terms

Sn  =  sum of the n terms

tn  =  t1 + (n - 1)d     --->     65  =  -5 + (n - 1)(5)

                                          65  =  -5 + 5n - 5

                                          65  =  -10 + 5n

                                          75  =  5n

                                            n  =  15

Sn  =  n(t1 + tn)/2     --->     Sn  =  15(-5 + 65)/2

                                          Sn  =  450


So ur answer rounds up to 450
