Answer:
32/40, 4/5
Step-by-step explanation:
All these ratios are follow the ratio 4:5 meaning they are equivalent to "64:80".
8:12=0.666667
16"24=0.666667
120:160=0.75
A Yes as the x values are all different
B f(x) = 5x + 14
when x = 2 , f(x) = 5(2) + 14 = 24
x = 5, f(x) = 39,
Each value of f(x) is greater than corresponding ones in the function in A.
when x = 9 f(x) = 59 which is greater than for first function ( =12)
First function is a decreasing while f(x) is increasing
C f(x) = 64 = 5x + 14
5x = 64 - 14 = 50
x = 10
Answer:
70
Step-by-step explanation:
First add the tens: 20 + 30 + 10= 60
Now add the Ones: 7 + 2 + 4= 13
now add them all together: 60+13=73
so the best estimate is 70
