** Ik this might sound stupid but it helps
Draw the point on a graph. Then imagine the the line x=3 as the straight edge of protractor and do a full 180° on the line. it should land in the 4th quadrant and on the same line of x=3
We know the unit price is $1.75 and we know that she bought 55.56 cubic yards of topsoil. In order to find out how much she paid for all 55.56 cubic yards, we would multiply.
55.56 • 1.75 = 97.23
Therefore, your answer is B. When dealing with decimals, you don't move the decimal point unless exponents are involved. (:

Answer:
x = 4
, y = 2
Step-by-step explanation by elimination:
Solve the following system:
{2 x + 3 y = 14 | (equation 1)
x + 5 y = 14 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{2 x + 3 y = 14 | (equation 1)
0 x+(7 y)/2 = 7 | (equation 2)
Multiply equation 2 by 2/7:
{2 x + 3 y = 14 | (equation 1)
0 x+y = 2 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{2 x+0 y = 8 | (equation 1)
0 x+y = 2 | (equation 2)
Divide equation 1 by 2:
{x+0 y = 4 | (equation 1)
0 x+y = 2 | (equation 2)
Collect results:
Answer: {x = 4
, y = 2
