Evaluate 48 + 24 ÷ 8 − 22
Licemer1 [7]

Answer:

Using PEMDAS, we would first divide 24/8=3. Then, since there is no multiplication or division left, we can finish up with adding and subtracting. So, 48+3-22=29.

So 29 is the answer.

Can you help me please.

Answer:

  a.  (-1/2, 5)

Step-by-step explanation:

The coefficients of x have opposite signs, so the x-terms can be eliminated by adding the two equations.

  (2y -12x) +(3y +12x) = (16) +(9)

  5y = 25 . . . . . . simplify

  y = 5 . . . . . . . . .divide by 5

This matches only answer choice A.

__

<em>Check</em>

The other part of answer choice A is x = -1/2. We can test this to make sure it works:

  2(5) -12(-1/2) = 16

  10 + 6 = 16 . . . . . . true, the selected answer works OK
