Answer:
the cost for each drink = $2.54
Step-by-step explanation:
The statement formed a simultaneous equation :
3x + 6y = $21.12
4x + 9y = $30.41
solving simultaneously,you have that ; x = 2.54, y = 2.25
Answer:
6=2(y+2)
distributive property
6=2(y)+2(2)
6=2y+4
-4 -4
2=2y
-- --
2 2
divide two in both sides to get y by itself
y=1
add 1 1/10 + 1 2/5
first get both fractions with the same bottom number: 2/5 = 4/10 ( multiply both numbers by 2)
so now you have 1 1/10 + 1 4/10 = 2 5/10
5/10 reduces to 1/2
so answer is 2 1/2 inches, and since the level is going down it would be negative 2 1/2 inches
Circumference = 2πr
r = 9
Circumference = 2π(9)
Circumference = 18π
Circumference = 18(3.14)
Circumference = 56.52
Distance: 56.52 meters
