Answer:

972

Step-by-step explanation:

The first term is (9x)^3, so the coefficient of x is 9. Since the degree is 3, the second term must have a multiplier of (3 choose 1). 1458 / (3 choose 1) = 486.

486 / (9^2) = 6. Therefore, the coefficient of y must be 6. Since the second term is negative, the coefficient of y is also negative. Thus, this can be written as (9x-6y)^3. Solving for the xy^2 term gives us (3 choose 2) * 9 * 6^2 = $\boxed{972}$ or the third option.

Celeste wants to have her hair cut and permed and also go to lunch she knows she will need $50 the perm cos twice as much as her

e-lub [12.9K]

Lets say the cost of her haircut is $x. This makes the cost of her perm 2x (twice as much). If lunch ($5), the perm ($2x) and the haircut ($x) cost, in total, $50, we can say:

50 = 5 + 2x + x
Combine like terms:
50 = 5 + 3x
Subtract 5 from both sides to isolate 3x
50 - 5 = 3x
45 = 3x
Divide all by 3 to isolate x
x = 45/3
x = 15

So the haircut is $15 and the perm is $30 (2*$15).

Answer:

Solution given;

<ABD=<BAC+<ACB

Since exterior angle of a triangle is equal to the sum of two opposite interior angle

26x+20=19x-15+9x+25

solve like terms

26x+20=28x+10

subtracting both by 10

26x+20-10=28x+10-10

Subtracting both side by 26x

10=28x-26x

2x=10

dividing both side by 2

2x/2=10/2

x=5

Now

<ABD=26*5+20=l50°

The value of <ABD is 150°

your class had a few fundraisers this year. if they raised $ 1036.25 from selling candy bars, $524 from dance ticket sales, and

nasty-shy [4]

Amount raised from selling candy bars = $ 1036.25.

Amount raised from dance ticket sales = $524 and

Amount raised from valentines flower sales = $206.58.

In order to find the amount your class raise altogether, we need to add all those amounts.

Total amount = $ 1036.25 + $524 + $206.58 = $1766.83.

Therefore, your class raise $1766.83 altogether.
