There are some missing details in the question. I found a similar question with some addition of details as follows:
The Sugar Sprinkles package contained 3/4 of a cup of the mix that needs to be mixed with 2 2/5 cups of flour, 2 1/4 cups of brown sugar, 3 3/8 and cups of water. The directions indicate to use 0.1125 of a cup of dough to make one cookie and 1 batch should make a total of Sugar Sprinkles cookies.
The Chocolate Turtle package contained 0.875 of a cup of the mix that needs to be mixed with 3.25 cups of flour, 2.5 cups of brown sugar, and 3.75 cups of water. The directions indicate to use 1/8 of a cup of dough to make one cookie and 1 batch should make a total of Chocolate Turtle cookies. The difference in the number of cookies of each type is _____
Answer:
Difference in number of cookies is 1
Step-by-step explanation:
This question is quite a tricky one. You have to be careful when answering it.
For sugar sprinklers, it contains 3/4 of a cup of the dough. For every 0.1125 of a cup, 1 cookie can be made.
So, 3/4 ÷ 0.1125
= 0.75 ÷ 0.1125
= 6.66667
Hence the most can be made is 6.
Note that we do not use the other volume because 0.1125 cup of a dough is the amount of cup from the original mix
The same applies to chocolate turtle cookies. It contains 0.875 of a cup. For every 1/8 of a cup can make 1 cookie.
0.875 ÷ 1/8 = 7
So the difference in the number of cookies is 7 - 6 = 1
Answer:
C
Step-by-step explanation:
Given the 2 equations
x + y = 4 → (1)
x - y = 6 → (2)
Add the 2 equations term by term to eliminate y, that is
2x = 10 ( divide both sides by 2 )
x = 5
Substitute x = 5 into either of the 2 equations and evaluate for y
Substituting into (1)
5 + y = 4 ( subtract 5 from both sides )
y = - 1
solution is (5, - 1 ) → C
Step-by-step explanation:
2x - 5 = 1/2*(3x - 13)
4x - 10 = 3x - 13
x = -3
