Answer:
k=4
Step-by-step explanation:
5-7k=-4(k+1)-3
Distribute
5-7k=-4k-4-3
Combine like terms
5-7k=-4k-7
Add 7k to each side
5-7k +7k = -4k+7k-7
5 = 3k-7
Add 7 to each side
5+7 = 3k-7+7
12 = 3k
Divide by 3
12/3 = 3k/3
4=k
Answer:
3( 73/84 )left over
Step-by-step explanation:
She had 6 gallons in total
2/3+1/4+1/2+5/7=179/84 = 2 ( 11/84)
6/1-179/84 = 325/84 = 3(73/84)
She used 179/84
She have left 325/84
179/84 + 325/84 = 6
With mixed numbers:
2 11/84
3 73/84
2+3=5 11/84+73/84= 84/84 =1
5+1=6
3. you cannot simplify √30
