D
Step-by-step explanation:
i did a test with the same question
4*(10*12/2)+4*(12*9)+(12*12)= 816 ft^2
the surface area is 816 ft^2.
Let number of ticket be x
and number of students ticket will be 3x
total ticket sold is 532
x+3x=532
4x=532
x= 532/4
X= 133
Answer:
It is not possible for a system of linear equations to have exactly two solutions.
Step-by-step explanation:
A system of linear equations is composed of multiple equations that describe straight lines. Two straight lines can be parallel (which means that the system has no solutions), they can intersect at a single point (one solution), or they can be congruent (all points are shared by both lines, infinite solutions). Therefore, a linear system cannot have exactly two answers. At least one of the equations in the system would have to be quadratic in order to achieve exactly two answers.
