Let
C=child ticket
A=adult ticket
then
A=C+8 ........(1)
and
7A+2C=173 ......(2)
Substitute (1) in (2)
7(C+8)+2C=173
distribute
7C+56+2C=173
isolate C and solve
9C=173-56=117
C=$13
hence adulat
A=$13+$8=$21.
The scale factor would be -8 because...
126 inches / 7 inches = 8 inches.
Because the car is bigger than the scale, it would be a negative scale factor.
To evaluate an expression in maths, plug in he value of the variable, then simplify the expression following the order of operation.
Assuming we are given the expression, 3x + (2x - 1), and we are required to evaluate the expression, the following shown below is how to evaluate the expression if we are told that x = 1.
- First step is to plug in the value of the variable, x, into the expression:
3(1) + (2(1) - 1)
3 + 2 - 1
- Using the order of operation, simply
4
Therefore, to evaluate an expression in maths, plug in he value of the variable, then simplify the expression following the order of operation.

Answer:
300%
Step-by-step explanation:
By increasing the down payment from 1,000 to 4,000, how does the total purchasing cost change?
If down payment is increased from 1000 to 4000
Icecrement = 4000-1000
Increment =3000
Percentage increase = 3000/1000×100
Percentage increase = 3000/10
Percentage increas=300%
