Well the answer is 34.
the angles are opposite side exterior angles of two parallel lines with a line that intersects both. The opposite side exterior angles will always be equal to each other

a will represent apples, b will represent berries, and c will represent cherries.
34 = 2a + 1b + 4c
35 = 3a + 2b + 2c
49 = 5a + 3b + 2c
Solve for on variable in the first equation.
b = 34 - 2a - 4c
Plug that into the second equation and solve for a different variable.
35 = 3a + 2(34 - 2a - 4c) + 2c
35 = 3a + 68 - 4a - 8c + 2c
35 = -a + 68 - 6c
-33 = -a - 6c
33 = a +6c
a = 33 - 6c
It gets a little confusing here but you plug in what both a and b are equal to until you have solved for c.
49 = 5a + 3b + 2c
49 = 5(33 - 6c) + 3b + 2c substitute a with 33 - 6c
49 = 165 - 30c + 3b +2c
49 = 165 - 28c + 3b
-116 = -28c + 3(34 - 2a - 4c) substitute b with 34 - 2a - 4c
-116 = -28c + 102 - 6a - 12c
-116 = -40c + 102 - 6(33 - 6c) again substitute a with 33 - 6c
-116 = -40c + 102 - 198 + 36c
-116 = -4c - 96
-20 = -4c
4c = 20
c = 5
a = 33 - 6c
a = 33 - 6(5)
a = 33 - 30
a = 3
b = 34 - 2a - 4c
b = 34 - 2(3) - 4(5)
b = 34 - 6 - 20
b = 8
Apples cost $3 per pound
Berries cost $8 per pound
Cherries cost $5 per pound

There are certain reflection rules across whatever you want to reflect. In this case, we want to reflect the shape across the y-axis.
When you reflect a point across the y-axis, y coordinate remains the same, but the x-coordinate is transformed into its opposite, means the sign of the x coordinate will be changed from positive to negative or negative to positive.
Thus,
(x , y)→(-x , y)
X’ = (2, –15) is the point given to you, which is the reflected point. To find the pre-image, consider the rule described above.
X’ = (2, –15) → X = (-2 , -15)
In case, the question says it is reflected over x-axis then we would use another rule which says When you reflect a point across the x-axis, the x-coordinate remains the same, but y-coordinate is transformed into its opposite, means the sign of the x coordinate will be changed from positive to negative or negative to positive.
Then,
X’ = (2, –15) → X = (2 , 15)

y=number of 10 dollar tickets
total is 300 so
x+y=300
value=number of certain ticket times value of ticket
value of 4dollar ticket=x times 4=4x
value of 10dollar ticket=y times 10=10y
total value=1950
therefor
4x+10y=1950
the equations are
x+y=300
4x+10y=1950
very confusing since the options are doublepasted or something
answer is A

And since squares are rectangles, you know that some rectangles are squares--namely, the squares are!
We teach children "this is a rectangle, that is a square. The rectangle's sides are different lengths". But when you grow up, it's important to think of the square as a SPECIAL rectangle, because it is all that a rectangle is, and more.
A square is still a rectangle, but it's not just a rectangle, it's a (pedigreed) square.
In summary, yes a rectangle can be a square.
Hope this helped :)
