In 1926 the very dirt first test asked if a mans salary is 20 dollars a week and he spends 14 dollars a week how long will it take him to save 300 dollars

It is a solve for x equation. It is written as 300=x (20-14) first you do the subtraction in the brackets 300=x (6) then divide both sides by 6 to find x 50=x it would take 50 weeks for him to save 300$ (feel free to check that by putting 50 in for x and solving)

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

0 = ( 2 - 4 ) ( p + q )0 = ( 2 - 4 ) ( 2 + 5 i ),   by multiplying these0 = ( 4 + 10 i - 8 - 20 i )0 = 4 - 8 + 10 i - 20 i0 = - 4 -10 i   0 = 2 ( - 2 - 5 i )0 / 2 = - 2 - 5 i- 2 - 5 i = 0- 5 i = 2i = 2 / - 5
