The number of cookies packs needed if the treasurer buys 1 package of brownies bites is 5 packs
EquationTotal attendance = 75 peopleCookies in each pack = 12Brownies in each pack = 15Number of cookies pack = cNumber of brownies pack = b15b + 12c = 75
If 1 package of brownies is bought
15b + 12c = 75
15(1) + 12c = 75
15 + 12c = 75
12c = 75 - 15
12c = 60
c = 60/12
c = 5 packs
It is a reasonable value in this contextIf 9 packages of brownies are bought
15b + 12c = 75
15(9) + 12c = 75
135 + 12c = 75
12c = 75 - 135
12c = -60
c = -60/12
c = -5 packs

A function assigns the values. The value of (gof)(3) is -576.
What is a Function?
A function assigns the value of each element of one set to the other specific element of another set.
Given f(x)=x+21 and g(x)=-x², therefore, the value of (gof)(x) will be,
(gof)(x) = g(f(x))
= -(x+21)²
The value of (gof)(3) will be,
(gof)(3) = -(3+21)²
= -576
Hence, the value of (gof)(3) is -576.

The first step is to find the number of miles traveled per gallon of gas
63 miles / 3 gallons = 21 miles per gallon
Take the rate and multiply by the number of gallons used to get the distance traveled
d = r * g
d = 21 * 7

Our proportions are:

We multiply x times 2 and 3 times 6; upon doing that we obtain.
[tex]\multimap\quad \tt 2x=18[/tex]
Did you see that? 2 fractions turned into a little equation that we can solve within 5 seconds (or faster)!
To do that we simply divide both sides by 2, since x is multiplied by 2 and we need to get it all by itself on one side of the equal sign)

"A number" can be replaced with the variable, x"Plus" is obviously used to denote addition"Is" is used in place of an equal sign"Times" is used to show multiplicationWriting Out the Expression
In the figure, we see that the blocks "x" and "8" is equal to the block "5x". So, we can say that x plus 8 is equal to 5x. Then, using the keywords above we can replace the variables and numbers.
This creates the new sentence, "A number plus 8 is equal to five times a number."
