Translate the sentence into an equation. Five times the difference of a number and 8 is 45. A. 5 ∙ (m – 8) = 45 B. 5m – 8 = 45 C. m – 8 ∙ 5 = 45 D. 5 ∙ (m + 8) = 45
difference means subtract! now try!
nvm b ?
okay how ?
i read it
im reading it
and i dont get it anymore
break into 3 parts write it in your notebook then draw lines like this |dw:1441396359500:dw|
five - times - the difference of a number and 8 - is - 45
5*(m-8=45 thats how i get it
so a ?
Choose the equation that models the problem. Luisa won 17 tennis matches last summer. She played a total of 26 matches. How many matches did she lose overall? Let l represent the number of games that Luisa lost. A. l – 17 = 26 B. l + 26 = 17 C. 17l = 26 D. l + 17 = 26
total number of matches is 26 won 17 matches so how many lose out of 26 ?
9 matches she lost
right! now substitute I for 9 if you get equal sides then that equation would be the right answer
why do you think its A ?
i dont get it my brother sayed a
i said substitute i for 9
let's say \[\huge\rm I-17=26~~~~~9-17=26\] solve that both sides are equal ?
yes right !
