Wyatt solved the following equation:
ohaa [14]

Answer:

x = 2

Step-by-step explanation:

x + 1/2 (6x - 4) = 6

Expand the brackets.

x + 3x - 2 = 6

Add like terms.

4x - 2 = 6

Add 2 on both sides.

4x = 6 + 2

4x = 8

Divide 4 into both sides.

x = 8/4

x = 2

LekaFEV [45]

Answer:

first off kyle wouldnt go on a picnic OR waste his money on anything other than monster energy so... i dont know what ur talking abt..

no im just kidding If that is the question, then $50 is his maximum.  So total cost of sandwiches 4.50s and total cost of chips ($6.00) has to be less than or equal to $50.

4.5s + 6 ≤ 50

s ≈ 9.8 so he can buy at most 9 sandwiches.

*brainlyEst would be nice..
