So dad is represented by x
son is represented by y
so x is (x=) 7 times his son (7y)
our first sentence is x=7y
10 years later (x+10, y+10) he will be 3 times as old as his son (x+10=3(y+10))
or 10+x=3(y+10)
so our sentences are
x=7y
and
x+10=3(y+10)
first we subsitute x=7y for x in the second equation
(7y)+10=3(y+10)
7y+10=3(y+10)
we distribute
7y+10=3y+30
subtract 3y from both sides
4y+10=30
subtract 10 from both sides
4y=20
divide both sides by 4
y=5
the son is currently 5 years old
x=7y
subsitute y=5 for y in equation
x=7(5)
x=35
the dad is currently 35 years old
in 10 years
dad is 45 and son is 15
dad=35
son=5
80 + 30
then add
80 + 30=110
then add the numbers you left out
3+ 4 = 7
and you get 117
Answer:
The answer is 32.5
Step-by-step explanation:
First start with (6x3) + ( 8 x 5 ) + ( 9 x 1 ) + ( 10 x 7 ) + ( 12 x 4 ) + ( 13 x 2 ) + ( 14 x 1 ). This equals 225 pounds for all of the pumpkins. The baker buys all of them so multiply 225 by 0.30 since each pound costs 0.30. 225 x 0.30 = 67.5 and the baker pays a 100 dollars so 100 - 67.5 = 32.5. The answer is 32.5.
P.S: I has this same question and 32.5 was correct. PLZ give me Brainliest. Thank you!
What are the statements. Give me that information and I will help answer.
The total numbers of cats, birds and dogs in the shelter is 37
the probability of selecting a cat from the shelter is 10/37
the probability of selecting a dog from the shelter is 15/37
probability of a dog and a cat is given by
10/37*15/37=150/1369
