log(b,N) = x converts to b^x = N. The base of the log is the base of the exponent. The exponent term is on its own side in the original log equation.
Answer: b^x = N
Let the constant stretch factor be x
then
3x + 4x + 2x = 72 Add the left side.
9x = 72 Divide by 9
x = 72/9
x = 8
Therefore the sides are
8*3 = 24
8*4 = 32
8*2 = 16
Total = 72 which checks.
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
