Lets say the price of a shirt is X, then the price of sweater is X + 3.95
Since a total cost is 71.65 for 3 shirts and 2 sweaters. 71.65 = (3*X) + 2*(X+3.95)
So, 71.65 = 3X + 2X + 7.9
71.65 - 7.9 = 5X
12.75 = X. Therefore, the price of a shirt is 12.75 dollars, and the price of a sweater is 16.7 dollars (12.75 + 3.95)

There are two equal tables.
We need to add bases and multiply that by the height divided by two.
7+3=10•1=10
Now multiply that by two since there are two tables.
10•2=20
So, the tables area are 20 feet squared.
Would it not be one hundred and[insert number]?
Answer:
line FG
Step-by-step Explanation:
In the diagram, line CD passes through
The slope of this line is found using the formula,
We substitute the values to get,
So line CD is the line with slope
From the graph we can see clearly that, the only line that is perpendicular to CD is line FG.
Line FG also passes through
We can verify that the product of these two slopes is negative 1.
Therefore the correct answer is C
Answer is (-1.5,5)
Midpoint formula is M= ((X1+X2)/2), ((Y1+Y2)/2)
So it becomes ((-4+1)/2), ((9+1)/2)= (-1.5,5)
