Answer:
i think its A
Step-by-step explanation:
The original price is 30$ because we know that the new price is worth 60% of the old price. We can set up an equation to model this: 0.60x = 18. Dividing both side by 0.60 gives us an original value of 30. If you take 40% off of 30 you get 18 — allowing us to check our work.
Answer: 78 miles
Step-by-step explanation:
Hi, since the distances form a right triangle ( see attachment) we have to apply the Pythagorean theorem:
c2 = a2 +b2
Where c is the hypotenuse (the longest side) and a and b are the other two sides of the triangle.
In this case the hypotenuse is the distance from Jonestown to Brighton (x)
Replacing with the values given:
x2 = 30^2 + 72 ^2
x2 = 900+5184
x2=6084
x = √6084
x = 78 miles
120 x 4 is 480. subtract 135 x 3 which is 405, and you get 75 pounds
