Answer:
186 books with the 55% increase
Step-by-step explanation:
120 times 55% increase = 66 more in increase
Now take the increase and add it to the original amount of books to get the number of books with the increase
66 + 120 = 186
Answer:
-5092500+12222s
Step-by-step explanation:
<h3><u>The value of x is 19.</u></h3><h3><u>The value of y is 4.</u></h3>
x = 3 + 4y
x + y = 23
Because we have a value for x we can plug it directly into the second equation.
3 + 4y + y = 23
Subtract 3 from both sides.
4y + y = 20
Combine like terms.
5y = 20
Divide both sides by 5.
y = 4
Plug this value for x back into the original equation.
x = 3 + 4(4)
x = 3 + 16
x = 19
