Answer:
x = -7/5 and x = 9/8
Step-by-step explanation:
To solve this equation, set both parts of the "expression" equal to 0.
5x + 7 = 0
Subtract 7 from both sides.
5x = -7
Divide both sides by 5.
x = -7/5
8x - 9 = 0
Add 9 to both sides.
8x = 9
Divide both sides by 8.
x = 9/8
Answer:
10.75
Step-by-step explanation:
The cost of an adult ticket is £6 more than that of a child ticket, so will be shown by c+6.
Now, we are told that the cost of four child tickets and two adult tickets is £40.50, so we can put this in an equation and solve for c:
(c+6)+(c+6)+c+c+c+c=40.50
6c+12=40.50
6c=28.50
c=4.75
so, a childs ticket is 4.75
now to find the cost of an adult ticket you add 6,
4.75 + 6
= 10.75
1 foot, 8 inches is the correct answer
