If there are 180 students sitting in 9 equal rows. The number of students sitting in each row will be 20.
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, at an assembly.180 students sit in 9 equal rows.
We have to find the number of students sit in each row
We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.
The number of students sitting in each row is found as,
=180 / 9
=20
Thus, if there are 180 students sitting in 9 equal rows. The number of students sitting in each row will be 20.

Answer:y=3
Step-by-step explanation:
Answer:(0,5)
Step-by-step explanation:
Y-3=2(x+1)
Rewrite it
2(x+1)=y-3
Sub. 0 for xto find y
2=y-3
Y-3=2
Y=2+3
Y=5
5-3=2(x+1)
2=2x+2
2x+2=2
2x=-2+2
2x= 0
X=0
To check
5-3=2(0+1)
2=2(1)
2= 2
It checks

Answer:
16
Step-by-step explanation:
3(y+4)-(x-1)
Let x =3 and y =2
3(2+4) - (3-1)
PEMDAS says do parentheses first
3(6) -2
Then since there are no exponents, we multiply
18 -2
Finally we subtract
18-2

Answer:
16
Step-by-step explanation:
Evaluate 3 (y + 4) - (x - 1) where x = 3 and y = 2:
3 (y + 4) - (x - 1) = 3 (2 + 4) - (3 - 1)
2 + 4 = 6:
3×6 - (3 - 1)
3 - 1 = 2:
3×6 - 2
3×6 = 18:
18 - 2
