Answer:
3x+.6y+12
Step-by-step explanation:
DIvide everything by -4:
-12x+2.4y-48
-12x/-4=12x/4=3x
2.4y/-4=-.6y
-48/-4=12
That would be 35 + 0.20*35 = $42
Answer: 110 -10x
Step-by-step explanation:
You do pemdas
So 11•10 = 110
Then -10•x = -10x
And then you get
110-10x
C=-y-a/b
Multiply c and y with b
-bc=yb-a
-bc-yb=a
Answer:
1,737.3 feet
Step-by-step explanation:
Let's assume the length of the bridge consists of 2 right triangles as shown in the diagram. Use pythagorean theorem to find the other missing leg of each right triangle.
Let the missing leg for each triangle be x and y respectively.
Length of bridge = x + y
✔️x = √(1115² - 860²) = √503,625
x ≈ 709.7 (nearest tenth)
✔️y = √(1340² - 860²)
y ≈ 1,027.6 (nearest tenth)
✔️ Length of bridge = 709.7 + 1,027.6 = 1,737.3 ft
