Hello There!! (:
I'm Here to help!
If we say Kelly orders 1 chicken salad, then it means she ordered 5 egg salads.
If she ordered x chicken salads, then she'll have to order the rest, which is <span>(6−x)</span> egg salads.
For first equation, let's set y to be the meal's price. It consist of the price of all chicken salads ordered and the price of all egg salads ordered:
<span>y=5x+4(6−x)</span>
Again, x represents number of chicken salads ordered, and y represents the meal's price.
A second equation would come to limit the price to the money Kelly has:
<span>y≤28
</span>
Notice there are more constraints to add on the values (x cannot be negative, no such thing negative number of salads or fractional number of salads) so just keep that in mind.
Now, since we know the price based on the number of chicken salads, we can say for what number of salads it matches the second restriction:
<span><span><span>5x+4(6−x)≤28</span><span>5x+24−4x≤28</span><span>x≤28−24</span><span>x≤4
Does this help you?
I Sure hope so have a goodnight ! (:

In a geometric progression:
a, b, c, d...
The common ratio can be obtained using:
b/a = c/b = d/c
b/a = 112 / 64 = 1.75
c/b = 196 / 112 = 1.75
d/c = 343 / 196 = 1.75
The common ratio = 1.75
2x(-5x-3)
2x(-5x)= -10x and 2x(-3)= -6x
= -10x sq - 6x
-10x is sq bc you are multiplying the same variable twice
Answer is 175
To start you need to work backwards from the mean so do 158*4 to give you the total of the revenue then simply minus what was given to get 175
Hope this helped
Answer:
Y= 1.5x
Step-by-step explanation:
What you would do is divide all of the minutes by the amount of pages to find how long for each rate for one page. (ex. 18/12, Michael reads 1 page in 1.5 minutes. 12/8, Michael reads 1 page in 1.5 minutes. 30/20, Michael reads one page in 1.5 minutes) Therefore, yes it is proportional, and the equation is y=1.5x (there is no y intercept)
I hope this will help
