The first one is:
x=2
y= -1
The second one has no solution.
Hi there! :)

Begin by using Pythagorean theorem to solve for the length of the diagonal of the base:
a² + b² = c²
Use the length and width in the equation:
8² + 3² = c²
64 + 9 = c²
73 = c²
c ≈ 8.54 cm
Now, we can find the length of the diagonal of the prism using our calculated diagonal of the base and the height. Use the same equation:
(8.54)² + 7² = c²
73 + 49 = c²
122 = c²
√122 = c
c = 11.05 ≈ 11 cm. The correct answer is B.
Answer:140
Step-by-step explanation:
35% of 400=0.35x 400 because of means multiply.
So 0.35x400=140

Answer:
$70c + $50
Step-by-step explanation:
When its says $70 per car, that means you multiply 70 by the amount of cars to know how much the total car. So in your equation you would $70c and c represents the amount of cars.
You would add $50 because that's how much tips they would get. So now your equation is $70c + $50
