4x - 5 = 11
4x = 11 + 5 = 16
4x = 16
Divide by 4 from both sides
X = 4
Answer: 18
Step-by-step explanation:
Add them all up
18+21+20+14+17=90
Divide by 5 since that is how many numbers there are
90/5=18
X= 3r+5/2 is the answer I believe
Answer: 0.6%
Step-by-step explanation:
Basically subtract 59 from 709 which is 650 , halve 650 which is 325 and then add 59 to the other 325 that u have to add to the first 325 to make 650 so
709-59= 650
650\2= 325
325 + 59= 384
So 384 cheeseburgers were sold and 325 hamburgers
384+325= 709
