X=number of books that cost 0.60
y=number of books that cost 0.75
x+y=16
0.6x+0.75y=10.95
solve
multiply second equation by 10 for nicity
6x+7.5y=109.5
multiply first equesiotn by -6 and add to second
-6x-6y=-96
<u>6x+7.5y=109.5 +</u>
0x+1.5y=13.5
1.5y=13.5
divide both sides by 1.5
y=9
sub back
x+y=16
x+9=16
minus 6
x=7
seven 0.60 books and nine 0.75 books
Luci cuts a board that is 3/4 yard long into pieces that are
3/8. The pieces she cut can be solve by dividing the board by length of the new
board. The length of the ¾ yards long divided by the desired length of 3/8
yards which is equal to 2 pieces.
Im pretty sure it would be 4^-2 because when you’re multiplying two different exponents you add them. i hope i helped!
7a+14 thats is the answer for the problem
Answer:
A. 1
Step-by-step explanation:
Since it's g(-4), we have to use the first option because that means that x is equal to less than -4.
3√x + 5
3 √-4 + 5
= 1
