Answer:
first or last depending how you are rounding the decimal
=> the best fit is the first one
Step-by-step explanation:
y = 2.55x - 2.15 when x = 5 => y = 10.6 approximately 11
y = 3.21x - 1.75 when x = 5 => y = 14.3 cannot equal or approximately 11
y = -2.15x + 2.55 when x = 5 => y = -8.2 cannot equal or approximately 11
y = 1.75x + 3.15 when x = 5 => y = 11.9 approximately 11
Answer:
x=11
Step-by-step explanation:
(x-3)/2=(x+1)/3
multiply (x-3)(3) and 2(x+1)
3(x-3)=2(x+1)
3x-9=2x+2
Get the variables on one side and numbers on another
3x-2x=3+9
x=11
Step-by-step explanation:
let the unknown number be x
1St step: twice the number is 2(x) =2x
2nd step: 2x -14
3rd step: 2x - 14=28...
1 is the answer b/c that's the only number it goes too
