Answer:

The answer is option B.

Step-by-step explanation:

Let the percentage be x

We have

\frac{x}{100}  \times 40 = 8 \\  \\  \frac{4}{10} x = 8 \\  \\ 4x = 80 \\  \\ x =  \frac{80}{4}  \\  \\ x = 20

Hope this helps you

How to solve for x 15 + 8x = 45 + 6x
Reil [10]

Answer:

15

Step-by-step explanation:

Let's solve your equation step-by-step.

15+8x=45+6x

Step 1: Simplify both sides of the equation.

8x+15=6x+45

Step 2: Subtract 6x from both sides.

8x+15−6x=6x+45−6x

2x+15=45

Step 3: Subtract 15 from both sides.

2x+15−15=45−15

2x=30

Step 4: Divide both sides by 2.

2x

2

=

30

The parabolic arch of a bridge over a one-way road can be described by the equation y = -x^2 + 6, where x and y ar emeasured in
Vladimir [108]
So check the picture below

if we check the solutions or zeros for the equation, we get \bf y=-x^2+6\implies 0=-x^2+6\implies x=\pm \sqrt{6}

and as you can see in the picture, the value of "x" when y = 3.5, or the height of the truck is  \bf y=-x^2+6\implies 3.5=-x^2+6\implies x=\pm \sqrt{2.5}

the truck, ends up with a clearance of \bf \sqrt{2.5}-1.5 on either side, so, the maximum clearance, the truck can have, those two clearances added together, \bf 2(\sqrt{2.5}-1.5)
