First, substitute the values of the variables into the equation:
2x+(3)(6)=36
Then, you must simplify,
2x+18=36
Then, you must factor out 18 to leave x and its coefficient alone on one side of the equation:
2x+18-18=36-18
Then you must simplify the equation and divide by 2 on both sides of the equation to factor out the coefficient:
2x/2=18/2
Then you will simplify and you will find the value of x:
x=9
Answer:
b. 1.69
Step-by-step explanation:
So to solve this problem we need to simply find the percentage increase from 11.8 to 12 =>
to solve this we would do 12 - 11.8 = 0.2 --> 0.2 is our "difference in the increase" -->
now we divide this by our amt. which is 11.8 --> 0.2/11.8 = approx. 0.0169
--> finally multiply that by 100 which is simply moving the decimal places 2 places right giving us the final answer of 1.69

Answer:
Supermarket gets 300 cupcakes.
Step-by-step explanation:
Given,
Total cupcakes = 525,
Since, the ratio of bakery and supermarket cupcakes = 3 : 4,
Let the bakery cupcakes = 3x and supermarket cupcakes = 4x
Where x is any positive real number.
So, the total cupcakes = 3x + 4x = 7x
![\implies 7x = 525](https://tex.z-dn.net/?f=%5Cimplies%207x%20%3D%20525)
Divide both sides by 7,
![x=75](https://tex.z-dn.net/?f=x%3D75)
Hence, the supermarket cupcakes = 4(75) = 300
