Abcd is a parallelogram. if angle b is equal to (2x)° and angle a is equal to (-x + 120)°, find x.

In parallelograms, the two adjacent angles always add up to 180. So, that means that angle A + angle B = 180:

2x + (-x + 120) = 180

Solve for x:

x = 60

8 apples are left.

step-by-step explanation:

10-2=8

10 apples

take 2

now u have 8

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 !
