$139 - $121 = $18
(139-121) / 4 = b
BTW
he would only be able to buy 4 buns because he only has $18 dollars left and 4 buns x 4 dollars = a total cost of 16 dollars so
Luke would only be able to buy 4 buns and have $2 left over
Answer: the answer is C
Well if you follow PEMDAS you would have to do the parentheses first but you can’t subtract 18 from a variable (Z) so then you move on to the 2 and you have to do the opposite so you don’t multiply both sides by 2 you have to divide both sides by 2. And that’s how u get C
Answer:
1/3
Step-by-step explanation:
i found it easily also im good with slopes :)
6(-4x - 7) - 4(x - 6) Distribute 6 into (-4x - 7) and -4 into (x - 6)
(6)(-4x) + (6)(-7) + (-4)x + (-4)(-6) (two negative signs cancel each other out and become positive)
-24x - 42 - 4x + 24 Combine like terms(terms that have the same variable and power/exponent)
-24x - 4x - 42 + 24 (I rearranged the terms to be next to their like term)
-28x - 18 Your answer is D
