So you wanna find the area of each surface:
For the large square surface in the top you do 12*15=180 and there are two large squares faces so you multiply 180 by 2 which equals 360 then you find the small rectangle faces: 5*15=75 and multiply by 2 Bc there are 2 faces like that so it would be 75*2=150 then for the last faces you do 12*5= 60 *2= 120 at the end I add all of the faces up, 360+150+120=630
Answer:19+3x
Step-by-step explanation:
4+3(5+x)
Open bracket
4+15+3x
19+3x
"Increased by" means to multiply.
First, change the percentage to a number.
% ⇒ # : %/100
120(%) (120 ÷ 100) = 1.2
Now, you multiply.
5x × 1.2 = 6x
So, your answer is 6x.
You can use properties to solve equations with variables on both side by simplifying get the variable on one side. solve using inverse operations then check to see if it fits in right .
The total solution will include 17.5 cup of vinegar 0.5 cups of rubbing alcohol, and 2 cup of water which is a total of 35 cups of solution. Sofie will need 6 total containers to hold all of the solution.
<h3>
Number of container</h3>
1 cup of rubbing alcohol:
1 cup of rubbing alcohol=1÷1/2
1 cup of rubbing alcohol=2
Cup of alcohol needed:
Cup of alcohol needed=1+1/2+16
Cup of alcohol needed=17.5 cups
Total cups:
Total cups=17.5×2
Total cups=35 cups
Number of container:
Number of container=1+35/5
Number of container=1+5
Number of container=6 containers
Therefore the total solution will include 17.5 cup of vinegar 0.5 cups of rubbing alcohol, and 2 cup of water which is a total of 35 cups of solution. Sofie will need 6 total containers to hold all of the solution.
