Answer:
i hope this helps
Step-by-step explanation:
if you have 100 people in the room and you interviewed all of them, (for number 6). that means that 70% of these people ate breakfast
70% of the total amount of people you interviewed is 70. That means that 70 people you interviewed, eat breakfast.
Then it also says, "of those 70% of people, 25% eat cereal"
That means 25% of those 70 people eat cereal, or 1/4 of that population does.
0.25 * 70 = 17.5. (of course you cannot have part of a person, but this is an example)
and of the 17.5 people, 30% of them eats it with extra sugar.
so 30% of 17.5 people is 5.25.
that means that there are 5.25 people who eat cereal with extra sugar.
i hope this helps, it took a while for me to try to help with this
i noticed that you made a mistake. the amount of people that eat cereal is 25% of 70% of the people. that means you have to find 0.25 of 0.7 <--- (you multiply not divide)
(0.25x 0.7) = 0.175
The system:
y = 3 x - 7
15 x - 5 y = 14
---------------------
Using the substitution method:
15 x - 5 · ( 3 x - 7 ) = 14
15 x - 15 x + 35 = 14
0 · x = 14 - 35
0 · x = - 21
x , y ∈ ∅
Answer:
D ) There is no solution.
Answer:
35.5 cm
Step-by-step explanation:
The perimeter (P) is calculated as
P = (2 × 6.75 ) + (2 × 
)
= 13.5 + (2 × 11) = 13.5 + 22 = 35.5 cm
