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)
125/21 = 150/x
cross multiply
125x = 3150
x = 3150/125
x = 25.2 lbs....rounded up = 26 lbs <==
90.
You can get this by plugging into the equation.
h(-6) = 2(-6)^2 - 3(-6)
h(-6) = 72 + 18
h(-6) = 90
2 digit meaning that it has 2 numbers. For example, 66 is a two digit number.
Now, they also said it must be prime, meaning that its factors can only be 1 and itself.
Also, it must be odd.
Answer: 67
Now, do the same, except the number must be composite, as meaning that it has other factors.
Answer: 21
Answer: Three Dollars
Step-by-step explanation: The factors and prime factorization of 12 and 15. The biggest common factor number is the Greatest Common Factor number. So the greatest common factor 12 and 15 is 3.
If you think about it it is just greatest common factor.
the factors of 12 are 1, 2, 3, 4, 6, 12
The factors of 15 are 1, 3, 5, 15
the highest number they have in common is 3
so the answer to your question is three.
