A master baker can decorate a cake in 6 minutes and a student baker can decorate the same cake in 12 minutes. If they work together on one cake for one min what part of the cake is left to decorate

3/4

Step-by-step explanation:

so if it takes the master baker 6 minutes and they work on the cake for one minute that is 1/6 if it takes the student 12 minutes that is 1/12. so you do

1/12 x 1/6 and you find the LCD so that is 1x2/6x2 which makes 2/12 + 1/12 = 3/12 and you simplify by dividing the top and bottom by 3  which is 1/4 so if they decorated 1/4 of the cake that leaves 3/4 of the cake left.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
