35x=245
so you would divide both sides by 35
x=7
so it would take her 7 weeks or 1 month and 3 weeks to pay her friend back
30 people are already in the cabin.
If there’s 2/3 of the people that the cabin can carry, and 15 more can board, the 15 is the remaining 1/3, so to get the other 2/3 that we don’t know, you multiply 15 by 2, to get 30.
So all together, the cabin can carry 45 people.
Hope this helps!
Answer:
She has 9 5 cent stamps and 6 7 cent stamps.
Step-by-step explanation:
Let the number of five cent stamps be represented by F and the number of seven cent stamps be represented by S.
The difference between the number of five cent and seven cent stamps is 3
F-S=3
The sum of the collection from each type of stamp is 87 cents
5F+7S=87
Let us solve the equations simultaneously.
F-S=3
5F+7S=87
Using substitution method,
F= 3+S
5(3+S)+7S=87
15+5S+7S=87
12S=87-15
12S=72
S=6
F=3+S
=3+6=9
Therefore the number of five cent stamps is 9 and seven cent stamps is 6.
Answer:
11/12
Step-by-step explanation:
Answer:
12×5 =60
60-9 =51
51-4 =47
Step-by-step explanation:
the farmer has 12 chickens and each chicken laid 5 eggs which is 12×eggs laid(5) = 60
he thre away 9 eggs which means that we are going to subtract 9 from 60
60-9=51
then he took 4 eggs for himself know we subtract 4 from 51
51-4= 47
and 47 are the eggs he took to the market
