If we use X to represent the amount of quarts for the inside of the barn we can write an equation for this. The outside needs 19 quarts more so we can say this is (x+19)
x+x+19=107
2x+19=107
2x=88
x=44 quarts
convert to gallons by dividing by 4 and you have 11 gallons for the inside
The interval that is a solution for the graph to be positive is; D: -∞ < x < -1
<h3>How to interpret graph intervals?</h3>
For the graph to be positive, the x-values will have to produce y-values that are always positive.
Now, from the given graph, we can see that all the x-values less than -1 produce positive values of y which makes the graph positive.
Thus, the interval that is a solution for the graph to be positive is;
-∞ < x < -1

Answer: 31.57
Step-by-step explanation: 17.55 + 14.02 =31.57
To solve this problem, we need to recognize that Harry's age is given as "n". We can use this value and the given information to write expressions representing each person's age.
For Example, Jo is 2 years older than Harry and Harry's age is represented by the variable n. This means that n (Harry's age) plus 2 would equal Jo's age. This can be represented by the expression: n +2.
Next, we know that Kate is twice as old as Jo, and Jo's age is represented by the expression n+2. This means that 2 times Jo's age would be equal to Kate's age, or Kate's age = 2(n+2) or 2n +4.
Therefore, your answer is that Jo's age is n + 2 and Kate's age is 2n + 4.
Hope this helps!
