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.

Answer:
(-6, 1)
Step-by-step explanation:
x^2+5x<6,
x^2+5x-6<0,
(x^2-x) + (6x-6)<0,
x(x-1) + 6(x-1)<0,
(x-1)(x+6)<0,
-6<x<1

Consider this equation.
7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)
Mia solved the equation and determined that m = 2. Is she correct?
Answer:
No, Mia is not correct, the answer is -2.
Step-by-step explanation:
First we are going to use the distributive Property.
Step 1: 2(0.75+0.4). multiply the 2 out. .75m x 2=1.5m and 2 x .4= .8.
We get 1.5m+.8, so 2(0.75+0.4)=1.5m+.8
Now we are going to distribute on the oher side. 4(.5m-.8)
4x .5m=2m and 4x.8=3.2. Keep the sign the same and we get 2m-3.2, so 4(.5m-.8)=2m-3.2
We put this into the new equation to get 1.5m+.8+7.8=-6.4m+2m-3.2
Step 2: combine like terms
.8+7.8= 8.6 and -6.4m +2m =-4.4m
Plug that into our equation and we get 1.5mn+8.6=-4.4m-3.2
Step 3: Switch the sides
Bring -4.4m to the other side to get 1.5m+4.4m=5.9m
One side is 5.9m
We bring 8.6 to the other side to get -8.6. now we do -3.2-8.6=-11.8.
Our new equation is 5.9m=-11.8
divide by 5.9 on both sides to get our answer of
m=-2

Answer:
16 in.
Step-by-step explanation:
Notice that 20*1.5 = 30
Use this ratio for 24 except reverse.
16*1.5 = 24
Hope this helps! Have a nice day!
Answer:
16
Step-by-step explanation:
Real length: 30 ft
Drawing length: 20 in.
Real width: 24 ft
Drawing width: x
30/20 = 24/x
3/2 = 24/x
1/2 = 8/x
x = 2 * 8
x = 16
