Answer:
13(10) - 5 (6)
130 - 30
= 100
Step-by-step explanation:
You replace the x with 10, and the y with 60 and answer normally
13(30) = 130
5(6) = 30
130 - 30 = 100
x=(k-c)/6
6x+c=k
subtract c from both sides
6x=k-c
divide by 6 on both sides
x=(k-c)/6
her mistake was that she was counting all the fourths as a whole sandwich when she really wraped up four sandwiches in total because 16 divided by 4 which is how many she cut it up into is 4 whole sandwiches
Answer:
1,680 grams
Step-by-step explanation:
To solve this, we can create a proportion using this setup:
grams/people=grams/people
The recipe needs 480 grams for 4 people and x (unknown-what we are trying to find) grams for 14 people.
480 grams/4 people=x grams/14
480/4=x/14
Now, we have to solve for x-the grams needed for 14 people. To do this, we have to get x by itself. x is being divided by 14. To undo this, multiply both sides by 14, because multiplication is the opposite of division.
14(480/4)=(x/14)14
14(480/4)=x
14*120=x
1680=x

The question says the machine uses up m gallons of oil each hour on weekends.
This means that if the machine works for 24 hours each day, it implies that:
There are only two days on weekends i.e. Saturday and Sunday.
This means that if the amount of oil used in 1 day in the weekend is 24m, then we can say:
Saturday: oil used is 24m
Sunday: oil used is 24m
Total oil used during the weekend is:
