Answer:
(x, y) = (2, -6)
Step-by-step explanation:
Subtract the first equation from the second.
(8x -2y) -(5x -2y) = (28) -(22)
3x = 6
x = 2
Substitute this into either equation and solve for y.
8(2) -2y = 28
8 -y = 14 . . . . . . . . divide by 2
y = 8 -14 = -6 . . . . add y-14 to both sides
The solution is (x, y) = (2, -6).

Answer:
<h2>There are 664 diet soda</h2>
Step-by-step explanation:
Step one:
given data
total soda= 913
we are told that the ratio of diet sodas to regular sodas is 8:3
this means that for every 8 diet soda there is 3 regular soda
the total ratio is 8+3=11
Step two:
we are going to use part to all principle
let the diet soda be x
8/11=x/913
cross multiply
11x=913*8
divide both sides by 11
x=913*8/11
x=7304/11
x=664
There are 664 diet soda
Answer:
you multiple two numbers and you devide both sides you get the answer
The given samples are supposed to weigh 25.0 grams. This value is the basis when we talk about accuracy. In this case, we are talking about precision, so we opt to select the most 'precise' of the choices. The most precise measurement is C) 25.0122 grams. This is because it records up to +- 0.0001 grams.
