Answer:

x = -1, y = -1

( -1 , -1 )

Step-by-step explanation:

plug in -9y - 10 for x

5 ( -9y - 10) + 6y = -11

-45y - 50 + 6y = -11

-39y - 50 = -11

-39y = 39

y = -1

then plug in

-9(-1) - 10 = x

9 - 10 = x

x = -1

A 32 oz water bottle costs $10.70.
Anon25 [30]

Answer:

32 oz per water bottle

$0.33 dollars per ounce

Step-by-step explanation:

We are already given 32 oz as the amount per water bottle, so all we need to do is calculate the dollars per ounce. We can do this by dividing the cost of the water bottle by the number of ounces.

$10.70 ÷ 32= 0.334375 ------> 0.33

Rounding to the hundredths place we get $0.33.
