What is 7/10-14/100 in simplest form

Answers

(7)/(10)-(14)/(100)=0.7-0.14=0.70-0.14=0.56
first you have to make the fractions have the same denominator. so change 7/10 to 70/100. so that would be 70 minus 14. so the answer is 56/100. which can be simplified into 14/25.

A van travels 220 miles on 10 gallons of gas. Find how many gallons the van needs to travel 550 miles

Answers

Answer:  The required number of gallons to travel 550 miles is 25.

Step-by-step explanation:  Given that a van travels 220 miles on 10 gallons of gas.

We are to find the number of gallons that the van needs to travel 550 miles.

We will be using the UNITARY method to solve the given problem.

We have

Number of gallons required to travel 220 miles = 10.

So, number of gallons required to travel 1 mile =(10)/(220).

Therefore, the number of gallons required to travel 550 gallons will be

(10)/(220)* 550=(550)/(22)=25.

Thus, the required number of gallons to travel 550 miles is 25.
Use property of proportion:

220 mi ----------> 10 gal
550 mi ---------->   x

x=(10*550)/(220)=25 \ gallons

What is tn=6n-9.5,t15

Answers

Substituting 15 for t gives you...
15n = 6n-9.5
Now the trick is to move all terms with n to one side.
Subtract 6n from both sides...
9n = -9.5
Dividing both sides by 9 gives you...
n = -1 (1)/(18)
