<span>- 3/5 + - 3/4 
Multiply the fractions until both fractions have the same common denominator. Also, when you add a negative number, it's basically the same as subtracting that number as well.
- 12/20 - 15/20
Subtract the numerators but NOT the denominators.
Final Answer: -27/20 or -1 7/20 *Both answers are equivalent to each other.</span>

What is the best prediction of the amount of money earned when the lemonade stand has been open for 9 hours
abruzzese [7]

Answer:  $50

Step-by-step explanation:  Draw a line through the apparent center of the scattered dots. See where that line intersects 9 in the time scale (x-axis numbers) and the dollars earned scale (y-axis numbers)

It could be 50 or 55, but since there are a few more dots below the apparent midline, it may be best to use the lower estimate.

One number exceeds another by 26. the sum of the numbers is 58. what are the numbers
Gnom [1K]
First number = X

second number = x +26  ( exceeds means higher so add 26)

x + x+26 = 58

combine like terms:

2x + 26 = 58
 subtract 26 from each side:

2x = 58-26

2x = 32

divide both sides by 2:
x = 32/2
x = 16

first number is 16
second number = 16+26 = 42

Explain why 1/2 is not equivalent to 2/5.
juin [17]
Find ing the common denominator would make it 10.
for 1/2 to get to 10 you have to multiply by 5
1/2x5= 5/10
then you have to convert 2/5 to get the denominator to be 10
so you multiply 2/5 by 2
2/5x2= 4/10
5/10 is greater than 4/10
