Jeff is baking a cake. the recipe says that he has to mix 32 grams of vanilla powder to the flour.
jeff knows that 1 cup of that particular vanilla powder has a mass of 128 grams.
he added two over three of a cup of vanilla powder to the flour.
should jeff add more vanilla powder to make the exact recipe, or did he go over and by what amount?
a he needs to add one over four of a cup
b he went over by five over 12 of a cup
c he went over by one over four of a cup
d he needs to add five over 12 of a cup

If 1 cup of that particular vanilla powder has a mass of 128 grams, then of a cup of vanilla powder has a mass of

grams.

Since

grams and of a cup of vanilla powder is

then correct answer is that he went over by    of a cup.

correct choice is B.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
