The statement "Megan added more chemical solution to her aquarium than Desmond did" is true.
What is Unit of Measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
To compare the amount of chemical solution used by Megan and Desmond, we need to convert their rates to a common unit.
Let's convert Megan's rate to mL per 2 gallons by using proportions:
5 mL / 1 gallon = x mL / 2 gallons
Multiplying both sides by 2, we get:
10 mL = x
So Megan added 10 mL of chemical solution per 2 gallons of water.
Desmond's rate is already given as 8 mL per 2 gallons of water, so we can compare their rates directly.
Since 10 mL is greater than 8 mL, Megan added more chemical solution to her aquarium than Desmond did.
Therefore, the statement "Megan added more chemical solution to her aquarium than Desmond did" is true.

2. a-(-b) = positive
3. -a * b = negative
a. 87 + 65 b. -58+42
c. 73+(-55) d. -47+(-30)
Step-by-step explanation:

two positives(multiply or divide) = positive
two negatives(multiply or divide) = positive
a positive and a negative(multiply or divide) = negative
two positives(addition) = positive, (subtract) = depends on which integer is bigger
two negatives(addition) = positive, (subtract) = depends on which integer is bigger

How can you tell if an equation has more than one solution?
Answer:
If the equation ends with a false statement (ex: 0=3) then you know that there's no solution. If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.

Andre came up with the following puzzle. “I am three years younger than my brother, and I am 2 years older than my sister. My mom's age is one less than three times my brother's age. When you add all our ages, you get 87. What are our ages?”
Jada writes this equation for the sum of the ages:
(x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87
Match the meaning to each term of the equation.
x
x + 3
(x - 2)
3(x + 3) - 1
87
Answer:
x = 13
Andre is 13, Andre's brother is 16, Andre's sister is 11, Andre's mom is 47

Mom is 47
All together they are 87!

6x = 87 - 9
6x = 78
x = 78/6
