Answer:
Option D is correct.
Step-by-step explanation:
A team t-shirt costs $3 per adult and $2 per child.
Let the number of children be = c
Let the number of adults be = a
A team t-shirt costs $3 per adult that is 3a and $2 per child that is 2c, also given is that the total money collected is $275, so equation becomes:
On a certain day, the total number of adults (a) and children (c) who bought shirts was 100, equation becomes:
Now to know the number of children and adult, we can check by plugging in the values from options provided.
25 children and 75 adults = 25(2)+75(3)=50+225 =275
Rest options do not fulfill the requirements, so Option D is correct.
25 children and 75 adults
Equation 1:a + c=100
Equation 2: 3a + 2c=275
Have a nice day!

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.

Answer:
y = - 750
Step-by-step explanation:
Given
y = x³y² ← substitute x = - 5, y = - 3 into the expression
= × (- 5)³ × (- 3)²
= × - 125 × 9 ( cancel the 3 and 9 )
= 2 × - 125 × 3
= - 750
