Answer:
Step-by-step explanation:
The number of sandwiches sold: 73
The cost to make one sandwich: S
The profit the band earns from one sandwich: 0.2S
The amount of money that the band recieves for selling one sandwich:
S + 0.2S
One simple way to approach this is to subtract the number that DOESN’T have the variable with the solution by the sum.
Lets use problem 1 as the example:
1.) N+8=13
In this case, we subtract 13 by 8 and get 5, therefore N= 5.
2.) B+17=62
62-17= 45
B= 45
3.) X+5/6= 7/16
7/16-5/6= -19/48
X= -19/48
4.) y+1/7=5/8
5/8-1/7= 27/56
Y= 27/56
5.) 14+y=69
69-14=55
Y=55
6.) c+3.6=4.9
4.9-3.6=1.3
C= 1.3
Now for the word problems:
Lets use 7 as the example-
7.) a number increased by 19 is equal to 221.
Since we don’t know the number being increased by 19, that will be our variable. It will be re-written as so:
N + 19 = 221
Where N is the unknown number.
Using the same method of subtracting by the sum and the number that’s not the variable, we’ll get the solution to N
221-19= 202
N= 202
8.) N + 1 2/3 = 8
8 - 1 2/3 = 19/3= 6 1/3
N= 6 1/3
I really hope this helps

Thus, 476 is not divisible by 60

Hmm so to get a common denominator, both denominators would need the same factors. If they share any factors right now, then we don't need to worry about those. Let's mess with the blue term and see what happens. If we factor an <span>8g</span> out of each term, it gives us,<span><span><span><span>
g2</span><span>9−<span>g2</span></span></span>+<span><span>14+g</span><span>8g(3+g)

(gof)(-3) means the composition of two functions at x = -3.
(gof)(-3) can also be expressed as g(f(-3))
So, first we find f(-3)
f(x) = x² + 5
f(-3) = 9 + 5 = 14
g(f(-3)) = g(14)
g(14) = (14+5)/14 = 19/14
Thus, option C gives the correct answer
