-12+2c=2*c-6:2*c-6=0. C-6=0 and c=6.
We need to find the unit price of each box.
So, a box that weighs 30 Oz costs $4.50.
lets say that 30 Oz box is named box 1. We can use unitary method to find out the unit price of box 1.
Unitary method is a process to find the value of a single unit.
Now,
30 Oz costs $4.50
therefore, 1 Oz should cost:
dollars
So, the unit price of box 1 is $0.15.
Now, lets say the 20 Oz box is named box 2. Again we can use unitary method to find out the unit price of box 2.
Now,
20 Oz box costs $3.60
therefore, 1 Oz should cost:
dollars
So, the unit price of box 2 is $0.18.
Answer:
(x + 5)² + (y - 7)² = 13
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 5, 7) and r =
, thus
(x - (- 5))² + (y - 7)² = (
)² , that is
(x + 5)² + (y - 7)² = 13 ← equation of circle
Answer:
E
Step-by-step explanation:
15%-6%=9%
45x.09=4.05
45-4.05=$40.95 the jean will cost 40.95
