Step-by-step explanation:
The difference is 6 and because 6+4=10( 1 wk ),10+4=14( 2 wk ),14+4=18( 3 wk ),18+4=22( 4 wk ),22+4=26( 5 wk ).
If you are solving for a value, you can divide by -1
For example:
-x=5 (divide by -1)
x=-5
If you have an equation, you can negate every part
For example:
-x^2-2x+7=0 (negate)
x^2+2x-7=0

Step-by-step explanation:
I dont know sorry I'm not good at math.
Let x be the number of child admission tickets sold:
Child's ticket = x
There is a total of 145 tickets sold:
Adult = 145 - x
Total sales is $1020.80:
5.6x + 9.2(145 - x) = 1020.8
Solve for x:
5.6x + 9.2(145 - x) = 1020.8
5.6x + 1334 - 9.2x = 1020.8
3.6x = 313.2
x = 313.2 ÷ 3.6
x= 87
Answer: Number of child's ticket = 87
