Let x = the cost of the student discount card.
x + the cost of the passes = 29.50
x + 15(1.50) = 29.50
x + 22.50 = 29.50
Subtract 22.50 on both sides to isolate the variable x.
x = 29.50 - 22.50
x = 7
The student discount card is $7.
X = 36
being that you simplify both sides of the equation and solate the variable

➷ Writing it out like this will help:
7 : 3 : 2
? : 3.75 : ?
So, 3.75 is 3 parts as per this ratio
Divide this amount by 3 to get 1 part in the ratio
3.75 / 3 = 1.25
Now simply multiply all the other ratios by this value to find how much the others get:
1.25 x 7 = 8.75
1.25 x 2 = 2.5
Paula gets £8.75 and Henry gets £2.50
The amount altogether would be their individual amounts added together:
8.75 + 2.50 + 3.75 = 15
The total amount of money is £15.

Answer:
13 inches
Step-by-step explanation:
legs are 5 inch and 12 inch
we have to find hypotenuse
use formula
a^2 + b^2 =c^2
here a and b are legs of a triangle and hypotenuse is c so,
5^2 + 12^2 =c^2
25 + 144 =c^2
169 =c^2
=c
13 =c
therefore hypotenuse is 13 inches.
