Answer:
1 and 4/5
Step-by-step explanation:
!Keep, flip, change. (KFC rule)!
Equation: 3/2 divided by 5/6
1st: Flip the 5/6 to become 6/5
2nd: Change division to multiplication
New equation: 3/2∙6/5
Answer: 1 and 4/5
20=3x-1
move -1 to the other side
sign changes from -1 to +1
20+1=3x-1+1
20+1=3x
21=3x
divide both sides by 3 to get x by itself
21/3=3/3x
Cross out 3 and 3, divide by 3 and then becomes 1*1*x=x
21/3=x
Answer:
x=7
Answer:
4.25 pound
Step-by-step explanation:
Ratio is the quantitative relation between two amounts, which is being compared. In this question we are considering the ratio of weight to time consumed.
At the age 0
Weight = 2 pound
At the age 4 months
Weight = 3.5 pound
Proportion of Change = Change in Weight / Change in time = (3.5 - 2) / (4-0) = 1.5 / 4 = 0.375 pound per month
Weight after 6 months = 2 + (6 x 0.375 pond per month )= 4.25 pound
