Answer:
(3, 2) is the ordered pair for the given system of equations.
Step-by-step explanation:
Given:
2 x+ y = 8.......................(i)
y = - x + 5........................(ii)
<u>Put y = - x + 5 in equation (i)-</u>
<em>2 x + ( - x+ 5) = 8</em>
<em>2 x - x + 5 = 8</em>
<em>x = 8 - 5</em>
<em>x = 3</em>
<u>Now put x = 3 in equation (ii)-</u>
<em>y = - 3 + 5</em>
<em>y = 2</em>
Hence the (3, 2) is the correct ordered pair.
Answer:
504 dollares 56 dollars off
Step-by-step explanation:
Remember that when you are making stimates, you are going to roiund to the nearest dollar. Since $3.29 is closer to 3 dollars than four dollars, Sam should use the 3 dollars figure to estimate if he can afford 4 gallons of gas.
$3+$3+$3+$3=$12
The actual value is

, so $3 per gallon is indeed a god estimate.
We can conclude that the correct answer is: <span>
$3 + $3 + $3 + $3 = 12, so Sal can afford the gas.</span>
Answer
$22
Step-by-step explanation:
This is the answer because if we take 3 2/3 into a mixed number, it would be 11/3. If you multiply 11 to 6, you would get 66 and divide it by 3, and get 22.
