Answer:

The correct answer is option B and D.

Step-by-step explanation:

A. Shawn owed 40% of his tuition bill, b, after paying $6.00

=40%of (b-6)

B. The amount donated to the school was 40% more that $6.00.

Amount donated to the school = b

b=6+40% of b

C. The cost for a coat was 40% of the sum of b and $6.00.

= 40%(b+6)

D. Summer paid $6.00 more than 40% of b.

Amount by summer = x

= 40%b+6

Lunna [17]

$\huge\boxed{99}$

First, find out how much $10%$ of $90$ is.

$90*10%\ =\ 90*0.1\ =\ 9$

Now, just add that to $90$ .

$90+9=\boxed{99}$

There are $99$ members now.

Find the equation for (0,4)and (7,-10 )

sweet [91]

Answer:

y = -2x + 4

Step-by-step explanation:

First find slope:

$\frac{y_2-y_1}{x_2-x_1}=\frac{-10-4}{7-0}= \frac{-14}{7}=-2$ $\frac{y_2-y_1}{x_2-x_1}=\frac{-10-4}{7-0}= \frac{-14}{7}=-2$

We know equation of a line is y = mx + b, where m = slope and b = y-intercept, so we can plug in the slope:

y = -2x + b

The y-intercept of the equation is 4 because the coordinate (0, 4) is given. Therefore, the equation is:

y = -2x + 4

Answer:

[g+2/3g-1] ÷ [g^2+2g/6g+2]

g+2/3g-1 × 6g+2/g^2+2g

g+2/3g-1 × 2(3g +1)/g(g+2)

1/ 3g-1 × 2(3g+1)/g

2(3g +1)÷ g(3g-1)

6g+2 ÷[3g^2-g]

2x2 − 10x − 28 6x × 6 x − 7

Simora [160]

Answer:

no real solutions

Step-by-step explanation:

If equation is...

$2x^2 - 10x - 28 = 6x(6x) - 7\\2x^2 - 10x - 28 = 6x^2 - 7\\0 = 4x^2 + 10x + 21\\4x^2 + 10x + 21 = 0$

= no real solutions

The length of a rectangle is 7 more than twice the width x . The area is . 372

Bad White [126]

Answer:

x (7+2x) = 372,

where 372 is the are of this rectangle, and $x$ is its width.

Step-by-step explanation:

The width of this rectangle is $x$ . Twice that width will be equal to $2x$ .

The length of this rectangle is seven more than twice the width of this rectangle, or seven more than $2x$ . The length of this rectangle will thus equal to $7 + 2x$ .

The area of a rectangle is equal to the product of its width and its length. The width of this rectangle times its length will be equal to $x(7+2x)$ .

For this rectangle, this area is equal to 372. In other words,

$x(7 + 2x) = 372$ .

This equation about $x$ represents the relationship between the width, length, and the area of this rectangle.
