Answer 2

Answer:

x = 5

Step-by-step explanation:

Now to solve for our equation:

110 - 4x = 130 - 8x

Subtract 110 from both sides: (110 - 110) - 4x = (130 - 110) - 8x

Simplify: -4x = -8x + 20

Add 8x to both sides: (-4x + 8x) = (-8x + 8x) + 20

Simplify: 4x = 20

Divide both sides by 4: (4x / 4) = (20 / 4)

Simplify: x = 5

Hope this helps :)

Area of a triangle = 1/2 x base x height
Length of base = 15-5 = 10cm
Length of height = 15-5 = 10cm
1/2 x 10 x 10 = 50
So the area is 50cm^2

hope this helps

The constant of proportionality is 225.

Given that,

The number of calories burned by a 90-pound cyclist is proportional to the number of hours the cyclist rides. The equation to represent this relationship is y = 225x

Based on the above information, the calculation is as follows:

y = kx

So here the constant should be 225.
