Abdul's gas tank is 1/5 full. After he buys 7 gallons of gas, it is 7/10 full. How many gallons can Abdul's tank hold?
eduard

Answer: 14 gallons

Step-by-step explanation:

Let's call the total gallons of gas Abdul's tank can hold <em>x</em>.

Then, based on the information given in the problem, you can write the following expression:

\frac{1}{5}x+7=\frac{7}{10}x

Therefore, when you solve for x, you obtain the following result:

\frac{1}{5}x+7=\frac{7}{10}x\\\\\frac{1}{5}x-\frac{7}{10}x=-7\\\\-\frac{1}{2}x=-7\\\\-x=(-7)(2)\\x=14

Alicia and Thea are in charge of determining the number of T-Shirt to order to sell in the school store. Each Student collected
Nataly [62]

Answer: 360

Step-by-step explanation:

Since we are informed from the question that Alicia surveyed 50 students in the cafeteria from the population of 300 students, it simply means that she surveyed 50/300 = 1/6 of the students.

Since Thea surveyed the first 60 students who arrived at school one morning, the number of T-Shirts taht they should order will be:

= 1/6 × x = 60

x = 60 × 6.

x = 360

They should order 360 t-shirts for the students.
