You need to find the hypotenuse of the right triangle.
4² + 9² = c²
16 + 81 = c²
97 = c²
9.85 = c
There are 5,280 ft in a mile.
Multiply 9.85 by 5,280.
9.85 × 5,280 = 52,008
Multiply 52,008 by 110.
52,008 × 110 = <span>5,720,880
The estimated cost for constructing the street would be $</span>5,720,880.
Answer:
<h2>y = 4</h2>
Step-by-step explanation:
Put x = 9 to the equation 3x + 4y = 43
(3)(9) + 4y = 43
27 + 4y = 43 <em>subtract 27 from both sides</em>
4y = 16 <em>divide both sides by 4</em>
y = 4
