Answer:
They need to wash 72 cars
Step-by-step explanation:
2000 - 1640 = 360
360/5 = 72
Answer:
Step-by-step explanation:
the solution to the system
= find the intersection of two lines
method( one )
solve the equations ( find(x , y) )
( 1 ) y = -x +3
( 2 ) y = x - 3
now , we let ( 1 ) + (2 )
we have 2y =0 ,thus y = 0
from ( 1 ) y = - x +3 , we know y = 0 ,
we rewrite ( 1 ) as 0 = -x + 3,thus x = 3
method( two)
see the intersection point of two lines
so the ans is B.(3 , 0)

Question (3)
The given expression is,
Statements Proof
1). 1). Given
2). 2). Multiplication property of equality
3). 4x - 12 = 60 3). Distributive property
4). 4x = 72 4). Addition property of equality
5). x = 18 5). Division property of equality
Question (4)
Equations are,
5x + 10 = 30 ------(1)
5(x + 10) = 30 ------(2)
From equation (1),
5x + 10 = 30
5x = 30 - 10
x = 4
From equation (2),
5(x + 10) = 30
(x + 10) = 6
x = 6 - 10
x = -4
Therefore, solutions of both the equations are different.
