Answer:
5
Step-by-step explanation:
Let the number be x
Therefore 3times the number will be 3x
3x + 2= 17
3x =17-2
3x=15
x=15/3
x= 5
Answer:
y = 2/5x - 5
Step-by-step explanation:
y = 2/5x - 5
(If you go to desmos.com you can graph any equation. It really helps. I'm doing similar things in class, I use it all the time.)
Answer: 119
Step-by-step explanation:
Let the acre of wheat to be cultivated be x.
Since the farm must grow three times as many acres of corn as wheat, therefore, corn = 3x
The information given can be used to form a equation as:
42(3x) + 30x = 18564
126x + 30x = 18564
156x = 18564
x = 18564/156
x = 119 acres of wheat
