Answer:
x= 70
Step-by-step explanation:
In this question you have to use BODMAS. This indicates that you have to do the equation in the brackets first. Therefore, 3x15= 45. Then you add 25, which will give you 70.
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.
True, as 93 divided by 3 is 31; a whole number :)
