Answer:
the equation will be:
solving the equation we get x=8
Option B is correct.
Step-by-step explanation:
We need to write equation for this sentence:
The difference between a number and five equals three.
Let number = x
So, the equation will be:
Now, solving the equation to find value of x
Adding 5 on both sides
So, solving the equation we get x=8
Option B is correct.
Answer:

y
^2
Step-by-step explanation:
Here's my interpretation of your equation:
P=175e^(-0.090*25) (not P=175e^-0.090times 25 )
Then P = 175(0.105) = 18.4, or approx 18.
Answer:
82
Step-by-step explanation:
let X = the number of hamburgers sold
let Y = the number of cheeseburgers sold a combined total of 328 were sold
so: X + Y = 328
cheeseburgers = 3 times the number of hamburgers sold
so: Y = 3X
substitute 3X into the equation for Y
X + 3X = 328
4X = 328
divide both sides by 4 to get the variable X by itself
X = 82
so: 82 hamburgers were sold Friday
