Answer:
2
Step-by-step explanation:
To find the x-intercept using the straight-line equation, substitute y=0 and solve for x. To find the y-intercept, substitute x=0 and solve for y.
Price of one citron = 5 units
Price of one fragrant = 5/7 units = 0.71 units
Further explanation:
Let x be the price of one citron and
y be the price of one fragrant
Then according to given statement
10x+7y = 55 Eqn 1
7x+10y = 64 Eqn 2
Multiplying equation 1 by 7
This will be equation 3.
Multiplying equation 2 by 10
This will be equation 4.
Subtracting equation 3 from equation 4
So,
Price of one citron = 5 units
Price of one fragrant = 5/7 units = 0.71 units

23. – 10(-3)=30
24. -21-3= -24
Explanation:
We have followed the rules in adding and subtracting negative as well as positive values on the number line.
When adding two negative values, the result is a negative value.
When adding a negative and positive value, the result is either a positive or negative value depending on if the negative value is bigger or smaller than the positive value
When multiplying two negative values, the result is a positive value
When multiplying one negative and one positive value, the result is a negative value
To make you understand addition and subtraction of negative and positive numbers better, let us use a simple analogy. Assuming you are owing five oranges(-5) and you are only able to give two oranges(+2), you will still be owing 3 oranges(-3). Assuming also that you are owing 6 oranges(-6) and you are able to give 8 oranges(+8), you would have given excess oranges and would be owed two oranges(+2). Hence the results above.
