Part (a):

Turn percentage into a decimal.

26.8% = 0.268

Multiply.

67.5 * 0.268 = 18.09 (Answer)

Part (b):

Divide.

89.87 / 215 = 0.418

Turn into a whole number.

0.418 = 41.8 (Answer)

Turn percentage to a decimal to check.

215% = 2.15

Multiply

41.8 * 2.15 = 89.87

Hope This Helped! Good Luck!

Hi i need help in math pls i am really bad plssssssss

Answer:

The answer is a= $\frac{8x^2+11x+1}{2}$

Step-by-step explanation:

Combine like terms and we get,

$24x^2+83x+3=6ax$

$\frac{24x^2+33x+3}{6x} =a$ divide both sides of the equation by ax, and simplify further,

$\frac{x(8x^2+11x+1)}{2}$ notice that we can reduce the 24 over 6 1/2,

$\frac{8x^2+11x+1}{2} =a$ distribute and simplify further

And a= $\frac{8x^2+11x+1}{2}$

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$f(x)=x^{2}-2x+3$

This is the equation of a vertical parabola open upwards

The vertex is a minimum

The vertex is the point (1,2)

The y-intercept is the point (0,3)

The function does not have x-intercepts

Solve for b. ab+c=d<br> B=a+c/d<br> B=a/(c-d)<br> B=(d-c)/a

vekshin1

Answer:

b = (d-c)/a

Step-by-step explanation:

ab+c=d

Subtract c from each side

ab+c-c=d-c

ab = d-c

Divide by a

ab/a = (d-c)/a

b = (d-c)/a
