Answer: 3x+5x and 8x, 3(x+4) and 3x+12, a+b+a and 2a+b
Step-by-step explanation:
3x+5x is equal to 8x, so they're equivalent
3(x+4) is also equal to 3x+12 when you use the distributive property
a+b+a is also equivalent 2a+b
Answer: B
Step-by-step explanation:
Let's work this problem backwards. So, if he has y dollars left after spending 25% the second time or 3/4 of the money left. So, inverse it to get y. Then, do the same for 20% or 4/5, then 4/3y * 5/4 = 5/3y
Answer:
12/1
