Jakobe sold 150 coffee, 50 tea and 120 donuts at the coffee cart on Monday.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount of coffee, y represent the amount of tea and z represent the amount of donuts, hence:
x + y + z = 320 (1)
Also:
1.5x + 2y + 0.75z = 415 (2)
And:
x = 3y (3)
From the equations:
x = 150, y= 50 and z = 120

It's not a rational number because it's a continuous decimal. A rational number has an end.
Answer:
Unknown because unfinished
Step-by-step explanation:
where are the 3 appropriate reasons
5y + 2y = 22
(add 2y to 5y)
7y = 22
(divide each side by 7)
y ≈ 3.1
-2y + 6y = 3
(add 6y to -2y)
4y = 3
(divide each side by 4)
y = 0.75
