Answer: 
Step-by-step explanation:
To solve for y, we want to make sure y is isolated. SInce y is already isolated, all we need to do is divide both sides of the equation by 3.
[divide both sides by 3]

Let's say you had a cake that is cut into 5 equal slices. Then someone eats 2 of those slices. They ate 2/5 of the cake.
Now let's say you have another cake that you cut into 10 equal slices. If someone eats 4 of those ten, then they have eaten 4/10 = 2/5 of the cake.
Check out the diagram below to see a visual of how 4/10 and 2/5 are equivalent fractions.
Going from 2/5 to 4/10 has us multiply top and bottom by 2.
-----------
Similarly, 1/2 = 5/10 after multiplying top and bottom by 10
The original expression 2/5 + 1/2 turns into 4/10 + 5/10
Then you add the numerators to get 4+5 = 9, placing that over the common denominator of 10
<h3>Answer: 9/10</h3>

Answer:
27 cm³
Step-by-step explanation:
The surface area of a cube is ...
SA = 6s²
Then the edge length is ...
54 cm² = 6s² . . . . . please note that cm³ is not the appropriate unit for area
9 cm² = s² . . . . . .divide by 6
3 cm = s . . . . . . . take the square root
The volume of a cube is ...
V = s³
V = (3 cm)³ = 27 cm³
The volume of the cube is 27 cm³.
<u>Answer:
</u>
6.3 trees.
<u>Step-by-step explanation:
</u>
We have been given that Meryl needs to cut down 10.5 trees for every 5 cabins she builds.
Let us find the number of trees Meryl needs to cut down to build 1 cabin by dividing 10.5 by 5.
Now let us multiply 2.1 by 3 to find the number of trees Meryl needs to cut down to build 3 cabins.
Therefore, Meryl needs to cut down 6.3 trees, if she builds 3 cabins.
Slope is rise over run, so that would be 25/100 = 1/4
Slope is 1/4
