Answer:
4/10 is equivalent to 2/5
Step-by-step explanation:
because 4/10 is written as 0.4 in decimal form and so is 2/5, which means they are equivalent
12 inches = 1 foot
Let x=length of 2nd balance beam in feet
by ratio and proportion
1/12 = x/162
multiply noth sides by 162 to isolate x
(1/12)(162) = (x/162)(162)
162/12 = x
13.5 = x

Answer:
x=12.50
y = 17.50
Step-by-step explanation:
x = Amount of one Derek withdrawal
then amount of John withdrawal =x+5
Total withdrawals of Derek = no of times x one time withdrawal
= 7(x) = 7x ... i
No of John withdrawal = no of times x one time withdrawal
= 5(x+5) ... ii
Given that i and ii are equal
i.e. 7x =5(x+5)
7x = 5x+25
2x =25
x = 12.50 dollars
Y = 17.50 dollars
Checking part:
total derek withdrawal = 7(12.5) =87.50
Joh's withdrawal = 5(17.50) = 87.50
Since both are equal, our answers are right.
Solution: Derek withdrew each time 12.50 dollars each for 7 times and John withdrew 17.50 dollars each for 5 times.
