Answer:
90% of people marry their 7th-grade love. since u have read this, u will be told good news tonight. if u don't pass this on nine comments your worst week starts now this isn't fake. apparently, if u copy and paste this on ten comments in the next ten minutes you will have the best day of your life tomorrow. you will either get kissed or asked out in the next 53 minutes someone will say I love you
Step-by-step explanation:
Well since y= kx you should divide 12.6 by 3
Kieva made 8 cupcakes. 8 * 5 + 8 = 48 desserts.
In order to get this, you just have to try out different numbers of cupcakes and adjust based on whether it's too many desserts total, or not enough.
Another way to figure it out is to say that 1 cupcake + 5 cookies = 6 desserts. Then just divide 48 by 6 to get 8 which will then show you that Kieva made 8 cupcakes.
Multiply both sides of the fraction by 3.
3/4 = 9/12
For the first one:

you change the subtract 2 to add 2 on both sides. so it looks like the picture above. Then you would add 20 + 2 to equal 22. Then you divide that by 1 (from the t). that equals 22, so thats the answer.
