The original price was £348.
Adding 20% to to something is the same as multiplying by 1.2
Therefore, £290 * 1.2 = £348

72
Step-by-step explanation:
( 5+ y) + 6x
Let x = 10 and y = 7
( 5+ 7) + 6*10

The books are $16 each. To figure this problem out you have to start with the facts: Benny has $124, he buys seven books, then ends up with $12 left. So first subtract 12 from 124. That equals 112. Next divide 112 by 7, when you do that is comes out to the answer of 16! So $16 is the answer.
Answer:
x = 12
Step-by-step explanation:
We can use the Pythagorean theorem to solve
a^2 +b^2 =c^2 where a and b are the legs and c is the hypotenuse
9^2 +x^2 = 15^2
81 +x^2 = 225
Subtract 81 from each side
81-81 +x^2 = 225-81
x^2 = 144
Take the square root of each side
sqrt(x^2) = sqrt(144)
x = 12
