Eliminate x's by adding te 2 equations
add them
-2x+15y=24
<u>2x+9y=24 +</u>
0x+24y=48
24y=48
divide both sides by 24
y=2
sub back
2x+9y=24
2x+9(2)=24
2x+18=24
minus 18 both sides
2x=6
divide 2
x=3
x=3
y=2
(x,y)
(3,2)
7x/2 < 5
7x/2 * 2 < 5 * 2
7x < 10
7x71 < 10/7
x < 10/7

Answer:
1,360
Step-by-step explanation:
Ok, so for the first 6 questions, if each one can be answered 4 different times, that would mean that it would be 6 to the 4th power (or 6 x 6 x 6 x 6)
That would be 1296.
Then, we have the other 8 questions, that can be answered 2 different ways. That would be represented as 8 to the second power (or 8 x 8)
That would be 64.
Now, we have to add the two numbers together to get the total. 1296+64 = 1,360
That's how you get the answer! I hope this is correct!
