On Friday, a fruit stand sold a total of 92 apples and oranges. On Saturday, the fruit stand sold four times the number of apple
andreev551 [17]

Option A : a+o = 92 , 4a+2o = 284 is the right answer

Step-by-step explanation:

Let o be the number of oranges sold on Friday and

a be the number of apples sold on Friday

So,

A total of 92 was sold on Friday will yield the equation

a+o = 92

On Saturday,

4 times the number of apples = 4a

2 times the number of oranges = 2o

So,

4a+2o = 284

Hence,

The system of equations is:

a+o = 92\\4a+2o = 284

Option A : a+o = 92 , 4a+2o = 284 is the right answer

The coordinates of three vertices of a triangle are (3, 5), (-1, 5), and (-1, -3). What is the area of the triangle?
Marina86 [1]
If you would graph the triangle, one of the legs would be 8 and another would be 5 and the area of a triangle is bxh/2 so the equation is 8x5/2=20un².
Hope this helped! :)
