First person to answer both of these will get 10 points and Brainliest. But your answer has to be correct!
Answer:
The correct answer to a is 3 1/2 same answer for the other answer.
Answer:
a. 7/2 OR 3 1/2 Either answer should be acceptable
b. 82/15 OR 5 7/15 Either answer should be acceptable
Step-by-step explanation:
a. 5 3/4 = so first multiply the denominator, 4, by the whole number 5 so 4 x 5 is equal to 20. Add this to your numerator, 3.
20 + 3 = 23 so the new fraction is 23/4
Same thing with 2 1/4 4 x 2 = 8 + 1 = 9 9/4
23/4 - 9/4 = 14/4 simplify this to 7/2
b. Same process here:
7 2/3 3 x 7 = 21 + 2 = 23 23/3
2 1/5 5 x 2 = 10 + 1 = 11 11/5
This time, we need a common denominator
3 x 5 = 15
5 x 3 = 15
23/3 x 5/5 = 115/15
11/5 x 3 = 33/15
115/15 - 33/15 = 82/15

A 30 gallon tank is being filled at a rate of 2 gallons per minute. There was 6 gallons of water in the tank to begin. Let y represent the total amount of water in the tank and m represent the number of minutes. Write an equation to model the amount of water in the tank.
The amount of water in the tank represented by the equation as:
y = 2m + 6, where y is the total amount of water in the tank, m is the number of minutes.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
Let y represent the total amount of water in the tank and m represent the number of minutes.
We can model the amount of water in the tank using the equation:
y = 2m + 6
This equation states that the total amount of water in the tank (y) is equal to the rate of filling (2 gallons per minute) multiplied by the number of minutes (m), plus the initial amount of water in the tank (6 gallons).
For example, if we let m = 5, then y = 2 × 5 + 6 = 16, which means that after 5 minutes, the tank will contain 16 gallons of water.
