Ben can complete 4 math problems in 20 minutes. If he continues working .... amy sloved 3 / 5 of her math problems and had 24 left to do . how many .... I need help unscrambling these math words: dlrcaai tteiuqon sigeetnr eeianrdmr eoiatronp ..... Can somebody help me out here. I want to know why I am good with math ... www.jiskha.com/ math / - Cached - Similar
1. Let "me" be x such that
(3x + 3) / (5) - 4 = 2
3x + 3 = 30
3x = 27
x = 9
Check:
9X3 = 27 + 3 = 30/5 = 6 - 4 = 2
Same procedure with the others.
:)
Do them backwards...
1... 2 ==> +4 = 6 ==> * 5 = 30 ==> -3 = 27 ==>/3 = 9
2... 56 ==>/7 = 8 ==> + 7 = 15 ==>/5 = 3 ==> 24/3 =8
etc.
Or use a calculator...
