Answer:
(1, 10 )
Step-by-step explanation:
Given the 2 equations
- 9x - y = - 19 → (1)
5x + y = 15 → (2)
Adding the 2 equations term by term will eliminate the y- term
- 4x + 0 = - 4
- 4x = - 4 ( divide both sides by - 4 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (2)
5(1) + y = 15
5 + y = 15 ( subtract 5 from both sides )
y = 10
solution is (1, 10 )
To find the cost of one, divide 10.38 by 6, so
10.38/6 = 1.73
1.73 = price per battery
To find the price of 8, multiply the cost of price per battery with however many items you need, in this case 8 so,
1.73 x 8 = 13.84

So throwing a die hs 6 choices
26 letters
not sure what the points are
if you want to list all of the options then
multipliy 6 by 26
6 times 26=156
so 156 spaces
5,000,000 is the answer.
5,000÷0.001=5,000,000
