Answer:
P = (65 - R) / 60
Step-by-step explanation:
Raul's grandfather is Miguel
Raul's sister is Paula
We are given that Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister. If we write this mathematically, we have that:
R = M - (60*P)
Where R = Raul's age, M = Miguel's age and P = Paula's age
We are then given that Miguel is 65 years old, this means that M = 65
=> R = 65 - 60P
To find Paula's age, we make P the subject of formula, hence:
60P = 65 - R
=> P = (65 - R) / 60
We can use this expression to find Paula's age.
Answer:
$1400
Step-by-step explanation:
x= profit of 6th month
(200+300+400+500+500+x)
-------------------------------------- = 550
6
(1900+x)=3300
x=3300-1900
x=1400
Answer:
(5, 4 )
Step-by-step explanation:
Given the 2 equations
4x + 6y = 44 → (1)
4x + 2y = 28 → (2)
Subtracting (2) from (1) term by term eliminates the term in x, that is
(4x - 4x) + (6y - 2y) = (44 - 28), that is
4y = 16 ( divide both sides by 4 )
y = 4
Substitute y = 4 into either of the 2 equations and solve for x
Substituting y = 4 in (1)
4x + 6(4) = 44
4x + 24 = 44 ( subtract 24 from both sides )
4x = 20 ( divide both sides by 4 )
x = 5
Solution is (5, 4 )
Answer: 169 times
Step-by-step explanation:
Circumference : 64inches
Distance: 300 yards
We know that 1 yard is 36 inches.
300yd*36 = 10800inches
10800/64 = 168.75 but rounding up makes it 169 times.
