Select expression that is mathematically equivalent to xy−z+ (a - b) X c. y - 2 O a) x/y – z + (a - b)
b) Xc O x/(y – z) + (a - b)
c) Xc O x/y - 2 + a - b c O
d) x/(y – z) + a – b xc

Question:

Select expression that is mathematically equivalent to

a)

b)

c)

d)

Step-by-step explanation:

Given

Required

Determine its equivalent

Start by writing y - z in bracket;

becomes

When - is used as divide, it is equivalent to /

The given expression can then be rewritten as

Hence;

is equivalent to

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
