To solve equations with fractions, convert from a mixed number to an improper fraction then use the inverse. The inverse of a fraction is multiplying by the reciprocal of the fraction on both sides.
U is 10. If you subtract 11 first to get the variable and it's coefficient on its own, you see that 3u=30. To get the u on its own, you divide both sides by three. This gives you u=10
The most accurate way would be the fourth answer, because to estimate 66% of 47 you need to round both as closely as possible. 66% rounds closest to 2/3, and 47 is closest to 48
Y = mx + b.....the m is for the slope , (2,-4)...x = 2 and y = -4 now we sub -4 = 3/5(2) + b -4 = 6/5 + b -4 - 6/5 = b -20/5 - 6/5 = b - 26/5 = b
so ur equation is : y = 3/5x - 26/5 <== slope intercept form or if u need it in standard form : y = 3/5x - 26/5....(5) 5y = 3x - 26 -3x + 5y = -26...(-1) 3x - 5y = 26 <==standard form
