Answer:
11,13,15
Step-by-step explanation:
x+(x+2)+(x+4)=4(x+4)-21
3x+6=4x-5
11=x
x=11
x+2=13
x+4=15
Answer: 1 11/24
<u>Do Keep Change Flip (KCF)</u>
Keep: 7/12
Change: ÷ into ×
Flip: 2/5 into 5/2
Your new problem should be 7/12*5/2
<u>Multiply</u>
7/12*5/2=35/24
<u>Turn 35/24 into a Mixed Number (Dvide)</u>
35÷24 = 1 11/24
No Jeff is wrong, -2 has a higher value than -3.
I think the equation you are looking for is 10t=300d but you may have to simplify it.
