Answer:
The number Y is 862.
Step-by-step explanation:
Given : Y is a three digit number and the digits of Y add to 16 and The first digit is 4 times the third digit. The second digit is 3 times the third digit.
We have to find the number Y.
Since, Y is a three digit number
Let Y = abc , where a, b, c are the digits of Y.
According to given question ,
a + b + c = 16 ........(1)
also, The first digit is 4 times the third digit that is a = 4c ....(2)
and, The second digit is 3 times the third digit that is b= 3c ....(3)
Substitute (2) and (3) in (1) , we get,
⇒ 4c + 3c + c = 16
⇒ 8c = 16
⇒ c = 2
Thus, c = 2
Put c = 2 in (2) and (3) to find a and b ,
thus, a = 4c = 4(2) = 8
b = 3c = 3(2)= 6
Thus, number Y = abc = 862.
The number of flags that Sandra sees will be 24 flags.
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Ruth sees 11 flags in the park. Juno sees 4 more flags than Ruth. Then the number of flags that Juno sees will be given as,
⇒ 11 + 4
⇒ 15
Sandra sees 9 more flags than Juno. Then the number of flags that Sandra sees will be given as,
⇒ 15 + 9
⇒ 24
The number of flags that Sandra sees will be 24 flags.
