16/18=3/n
8/9=0.88888888 recurring
0.8888888 recurring*3=2 2/3
n=2 2/3
Replace x = 3 into <span>6/x + 2x^2
</span>6/x + 2x^2
=6/3 + 2 (3)^2
= 2 + 2(9)
= 2 + 18
= 20
Answer:
choice c. x = 6
Step-by-step explanation:
b(x) = (x+41, what is b—10)
it looks like b = x + 4
b = 10, then
10 = x + 4,
x = 6
Answer:
$1.65
Step-by-step explanation:
If h is the price of a hot dog, then the total bill was ...
4(2h +1.25) = 18.20
2h +1.25 = 4.55 . . . . . . divide by 4
2h = 3.30 . . . . . . . . . . . subtract 1.25
h = 1.65 . . . . . . . . . . . . . divide by 2
The price of one hot dog was $1.65.
First, you plug your given values in. Since x is 1.5, it will be multiples by 2x to get 3.2. Since y is -3, it will be added to 1 to get -2. Finally, the two are multiplied together to get -6.4 if I am correct.
