52 + 15 ÷ 5 · 6 + 2 = 1.25 45 49 50

52 + 15 ÷ 5 · 6 + 2 = 72

Step-by-step explanation:

PEMDAS

52 + (15/5) * 6 + 2  =

52 + 3 * 6 + 2 =

52 + 18 + 2 =

70 + 2 =

72

None of the given options are correct.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
