Answer:
Susan's measurements areincorrect. the measurements for sugar is 1 cup and for flour its 3 1/2 cups.
Step-by-step explanation:
(i dont know how to best answer section b but ill do my best)
A) 1/2 cups of sugar X2= 1 cup of sugar
1 3/4 cups of sugar X2= 3 1/2 cups of flour
B) When you have a mixed number like 1 and 3/4 cups like the example above, you are able to convert it into an improper fraction by multiplying the denominator withthe whole number and then addingthe remaining from the numerator. So with 1 3/4 cups:
4X1= 4+3= 7
So now you get 7/4 cups. to turn it back into a mixed number, just reverse the process.
Add the total of both groups and divide by the total number in each group
Group X = 535 / 18 = 29.72 mean
group Y = 500 / 18 = 27.78 mean
Group X has the higher mean
Answer:
The smallest number is 23
Step-by-step explanation:
Let x be the first number
x+1 is the next consecutive number
x+2 is the next consecutive number
The sum is
x+ x+1 + x+2 = 72
Combine like terms
3x+3 = 72
subtract 3 from each side
3x+3-3 = 72-3
3x = 69
Divide each side by 3
3x/3 = 69/3
x = 23
x+1 = 24
x+2 =25
The numbers are
23,24,25
