Answer:
commutative property
Explanation:
This is known as the commutative property of addition (and multiplication).
An easy way to remember the property is that the two elements commute, or exchange places, or that one element commutes from one side of the operation to the other, like a commuter (passenger) on a commuter train.
a + b = b + a
so we know there are 68 more student tickets than adult tickets so if we subtract 68 from 718 you get an even amount of tickets for both adults and students and you can divide that by 2 (718-68)/2 and we get 325, the amount of adult tickets sold.
Answer:325 Adult Tickets
Check answer: 325+(325+68)=718
The equation in the form y = mx + b is y = 0.35x + 36.
<h3>How to represent a linear equation?</h3>
The equation formed from the expression is a linear equation and should be expressed in the slope intercept form.
y = mx + b
where
Therefore,
y = mx + b
where
- x = the number of monthly minutes used
- y = the total monthly of the Next fell plan
using the coordinates, let's find m
(470, 200.5)(590, 242.5)
Hence,
m = 242.5 - 200.5 / 590 - 470
m = 42 / 120
m = 0.35
Therefore,
y = 0.35x + b
200.5 = 0.35(470) + b
200.5 - 164.5 = b
b = 36
Finally, the equation in the form y = mx + b is y = 0.35x + 36.

Answer:
x=120cc volume of 7% solution
Step-by-step explanation:
Saline solution(7% solution) +
Saline solution (19% solution) = Saline solution (11% solution)
Saline solution(7% solution): (0.07)(x)
x= unknown volume
Saline solution (19% solution): (0.19)(60)
60= given volume
Saline solution (11% solution)= (0.07)(x+60)
x+60= Total volume
solve for x
(0.07)(x) + (0.19)(60) = (0.11)(x+60)
0.07x +11.4 = 0.11x + 6.6
0.11x - 0.07x = 11.4 - 6.6
0.04x = 4.8
x = 4.8/0.04
x = 120 cc volume of 7% solution
Answer: A) y = 6x +3
Step-by-step explanation:
Let x represent the number of hours. $6 per hour can now be written as 6x.
Now, we must account for the $3 flat, fee and add it to 6x, getting 6x + 3
